Substrate tips
General tips
Handle unprinted and printed substrates with care, and preferably with cotton gloves, to avoid fingerprints. For heavy rolls, use a forklift, and two people wearing security shoes.
Before loading a roll:
●
Check that temperature and humidity in the room are within the recommended ranges for the
printer. See Environmental specifications on page 104 .
●
Check that neither the roll nor its core are bent or deformed, which may cause the substrate to jam in the printer.
●
If the roll has been stored in a place not offering the recommended environmental conditions, allow some time for it to adapt to the temperature and humidity of the printer's environment.
ENWW
Substrate tips

●
Check which is the correct side for printing, by reading the label inside the core or the note
inserted into the package (or see Tips for specific substrates on page 23 ).
●
Check that the substrate is correctly attached to the input core. Otherwise, you will see poor print quality due to substrate advance errors.
●
You may find it easier to load a roll if you first move the carriage beam to its highest position.
While loading a roll, make sure the leading edge is parallel and straight across the output core, and attached evenly (start taping the substrate to the core at the center, then move towards the edges).
After you have loaded a roll:
●
Make sure that the edge holders are set on both sides of the roll. Do not use any other Edge holder from another printer, only use the edge holders that came with the printer. An incorrectly loaded roll may cause waves or cockles in the substrate, leading to ink smearing and printhead crashes.
●
Check the correct carriage beam position for printing: high for thick substrates, normal for others.
See Set the carriage beam position on page 25 .
●
Check that you are using the correct substrate preset in the HP Internal Print Server and the correct
ICC profile and other settings in the RIP.
●
HP substrates are optimized to provide the best out-of-the-box printing experience with your printer. However, you may want to modify the ink limits or the number of passes; in which case, temperature, vacuum or tensions may need to be adjusted. You can create a new substrate preset from the default preset you are using and make your changes.
●
Use the HP Internal Print Server to check that any required calibrations have been done: color calibration, substrate-advance compensation, printhead alignment. See the Maintenance and
troubleshooting guide.
●
For the best print quality, the substrate should stay flat and unwrinkled in the printing zone, the substrate advance should be constant and the substrate should move straight.
●
Do not cut off pieces of substrate while the substrate is loaded into the printer. This may cause the remaining substrate to jam.
After printing, try to allow 24 hours before stacking, folding or rolling printed substrates.
NOTE:
Printing on porous substrates may result in visible vapor being generated from the waterbased ink.

Substrate configurations
The substrate can be loaded in a variety of different configurations to suit your different needs. Before loading, you must go to the HP Internal Print Server and select Substrate > Load/Unload, then select the configuration you intend to use.
The basic configurations are illustrated below. These configurations can be used for single-roll or dualroll printing, and for porous or non-porous substrates. Porous substrates require the use of the ink collector kit: see
The ink collector kit (LX850 only) on page 28 .
●
The roll-to-roll configuration is suitable when you intend to print a whole roll without cutting it until the input roll is empty. The substrate cannot be cut in mid-roll unless printing double-sided, and then it must be reloaded afterwards.
●
The roll-to-free-fall configuration (LX850 only) is suitable when you want to cut and remove each print as soon as it comes out of the printer. The substrate is kept under tension between the input roll and the tension roller; but it can be cut after the tension roller because then it is no longer under tension.
24 Chapter 3 Handle the substrate ENWW
●
The roll-to-free-fall with collector configuration (LX850 only) is suitable when you may want to cut the substrate and remove the output roll before the input roll is empty. The substrate is kept under tension between the input roll and the tension roller; but it can be cut after the tension roller because then it is no longer under tension.
Set the carriage beam position
The carriage beam position determines the vertical distance between the printheads and the platen. If it is too great, print quality will be impaired. If it is too small, there is a risk that the printheads will come into contact with the substrate, causing smears or damage.
To set the carriage beam position, go to the front panel and select the Substrate menu , then
Substrate management, and press OK . Select Carriage beam position. You can choose the highest position, a custom position or the normal position.
●
The highest position is not used for printing: it may be used for loading substrate or for maintenance tasks.
●
A custom position is used for thick substrates, or for substrates that wrinkle slightly due to heating.
TIP:
Try to avoid wrinkling by using substrates that do not wrinkle, or by using a slower print mode that will allow you to lower the drying temperature.
We recommend setting the custom position to the thickness of the substrate plus two or three millimeters. The current setting is indicated in the front panel by a √ mark.
ENWW
●
The normal position is suitable for unwrinkled substrates up to 0.7 mm (0.03 in) thick.
WARNING!
Keep away from the printer's moving parts until the carriage beam has reached its new position.
Set the carriage beam position
25
NOTE:
LX850 only: If you have installed the ink collector kit, the normal position and the lowest custom position are automatically adjusted to take account of that.
Prepare to print
The following steps that must be followed before the printer can print:
1.
Ensure that the ink collector kit is installed for porous substrates, and not installed for non-porous
substrates. See The ink collector kit (LX850 only) on page 28
.
2.
Start the printer. See
Turn the printer on and off on page 12 .
3.
Go to the HP Internal Print Server and select Substrate > Load/Unload to open the Printer
Configuration window.
4.
Select the printer configuration that you intend to use, and press Next to see the on-screen help.
26
NOTE:
The Skip Substrate load check box should be checked only if the printer has just previously had the same configuration (i.e. the same substrate, same profile), and because of a severe system error, you had to restart the printer.
5.
Load the substrate. Substrate loading instructions are displayed in the HP Internal Print Server window. For more detailed instructions, see
Load a roll onto the spindle on page 33
and
Load a roll into the printer on page 38 .
6.
Press the Load button in the HP Internal Print Server to start the substrate check, then enter the substrate type in the Loaded Substrate window.
TIP:
If the printer has been idle overnight with substrate loaded, and exposed to high or low temperatures, advance the substrate 13 to 25 cm (5 to 10 in) before printing, to avoid printhead crashes or ink smears on the substrate.
Chapter 3 Handle the substrate ENWW
The substrate edge holders
The purpose of the substrate edge holders is to prevent the substrate edges from lifting up and jamming while printing.
Standing in front of the printer, you should see the two edge holders on either side of the top surface of the substrate. Slide the edge holders to the edges of the substrate and make sure that they are properly positioned and not bent (which could cause a carriage crash).
TIP:
The edge holders are easy to deploy with the carriage beam at its highest position.
The correct position is illustrated below, where (1) indicates the edge of the substrate. The substrate should be free to move, and should not touch the ends of the edge holder.
CAUTION:
Wrongly positioned edge holders could severely damage the printheads and carriage.
Removal and replacement
When the printer is delivered, the edge holders are already installed on the print platen, and there is no need to remove them. When they are not being used they can be pushed to the side. However, the central edge holders used for dual-roll printing must be removed for single-roll printing and for the LX
850 when printing on textiles, as the ink collector kit must also be installed.
To install an edge holder, stand at the front of the printer and attach the rear of the edge holder to the rear of the platen, then pull the front of the edge holder towards you and attach it to the front of the platen.
CAUTION:
Do not bend the edge holder. It should remain perfectly straight, otherwise it could damage the printheads and carriage.
ENWW
The substrate edge holders
27
The ink collector kit (LX850 only)
Before printing on porous substrates, such as textile substrates, you must install the ink collector kit provided with your printer, to protect the printer from the ink that falls through the substrate. The kit must be removed before printing on non-porous substrates.

Chapter 3 Handle the substrate ENWW
●
In the roll-to-free-fall configuration, the output diverter is not needed.
●
In the roll-to-roll configuration, you are recommended to use both diverters, but in some cases you may be able to minimize wrinkles by changing the position of a diverter or even by removing one or both of them.
13.
14.
Load the substrate, which should pass outside the input diverter and inside the output diverter.
15.
Deploy the edge holders.
16.
If you have not already done so, go to the HP Internal Print Server and select Substrate > Load/
Unload. In the load configuration, ensure that the Ink collector box is checked.
17.
Lower the carriage beam to the normal position.
18.
You may need to enter the left edge position and the substrate width into the HP Internal Print
Server, if the printer cannot detect them.
Uninstall the kit
The ink collector kit must be uninstalled before printing on non-porous substrates.
1.
Raise the carriage beam to its highest position.
2.
If any substrate is loaded, unload it. Take care that it does not touch the ink collector foams, which may be wet with ink.
3.
Remove the edge holders, and clean them if necessary.
4.
Remove the diverter rollers.
ENWW

31
5.
Remove the ink collectors by pressing on the grips that secure them to the printer. To remove the rightmost ink collector, first move aside the blue spring-loaded clip.
6.
Store the ink collectors correctly in their box. If you stack them in a pile, they may warp.
7.
Before lowering the carriage beam to the normal position, go to the HP Internal Print Server and select Substrate > Load/Unload. In the load configuration, ensure that the Ink collector box is unchecked.
The curing plates
For efficient drying and curing, you are recommended to keep the curing plates up (horizontal) for textile and backlit substrates, and down (inclined downwards) for all other substrates.
Textile and backlit substrates
To raise a curing plate into the horizontal position, just lift it; it clicks into place.
32 Chapter 3 Handle the substrate ENWW
All other substrates
To lower a curing plate into the inclined position, you must pull the black knobs underneath the plate.
TIP:
If you find that you cannot get sufficient curing for a particular substrate with the curing plates down, you could try raising them to the horizontal position.
Load a roll onto the spindle
Single-roll printing and double-sided printing
The spindle has a pneumatic connector at one end and a gear at the other.
1.
Rest the roll securely on the Spindle Supports.
2.
Check that the gear is on the correct side (which depends on the intended winding direction).
3.
Insert the spindle into the roll.
TIP:
The spindle is quite heavy in order to ensure stiffness and so avoid skew and wrinkles, so two people are recommended for this operation. With only one person, you are recommended to put the roll on the Spindle Supports, lift one end of the spindle and insert it into the roll, then lift the other end carefully so that the first end does not fall out, and push the spindle into the roll.
4.
Connect the air gun to the pneumatic connector on the spindle, and inflate the spindle so that it cannot move inside the roll.
ENWW
Load a roll onto the spindle
33
5.
Note the position of the end of the roll on the scale marked at the geared end of the spindle. Its position should be not less than 3.2 cm (1.25 in) on that scale, otherwise the substrate may go out of the print zone and start touching the printer covers. The input and output rolls should be positioned identically on their respective spindles.
TIP:
When loading heavy rolls of inelastic substrates that are approximately half the spindle length, you may find it useful to load the substrate closer to the center of the spindle, to reduce the risk of skew, wrinkles and telescoping.
TIP:
If the substrate is telescoped on the input roll, there is a risk of substrate jams and damage to the printheads. Try to straighten the edges of the substrate to minimize telescoping on the input roll before loading it into the printer.
TIP:
Check that the substrate is attached to the input core.
The roll is now ready to be loaded into the printer.
TIP:
If you are a regular user of different substrate types, you can change rolls more quickly if you preload rolls of different substrate types on different spindles. Extra spindles are available for purchase, see
.
Dual-roll printing
You can print on two rolls at the same time by using the dual-roll spindles provided with your LX850 printer or available as accessories for your LX820 printer.
The dual-roll spindle is marked to assist you in positioning the differential hub.
34 Chapter 3 Handle the substrate ENWW
Loading the dual-roll spindles
1.
With the spindles inserted into the Spindles Supports, Ensure that the differential hubs on the input and output spindles are aligned with each other.
2.
When both differential hubs are correctly positioned, use an Allen key 4 to tighten the screws and secure them in place. If a differential hub is loose, the substrate could become skewed during printing.
ENWW
TIP:
You should tighten the screw until the washer touches the bolt. If you can still see the yellow spring, tighten the screw further.
TIP:
It will be easier to load the roll onto the spindle if you lock the differential.

13.
Use the same process to load the output spindle at the front of the printer, but load the spindle with two empty cores to receive the printed substrate.
Load a roll onto the spindle
37
Load a roll into the printer
The objective when loading substrate is to get a uniform tension across its width and along the substrate path to minimize the risk of skew, wrinkles and telescoping. There are three configuration of loading the substrate into the printer:
●
Roll-to-Roll configuration
●
Dual Roll-to-Roll configuration (LX850 only, an accessory for the LX820)
●
Roll-to-Free-Fall configuration (LX850 only)
In each of these types of configuration there is a Substrate Loading Tool available that will help
Load a roll (roll-to-roll configuration)
The substrate roll is mounted on the rear spindle and will be collected on the front spindle. The substrate goes from the rear spindle (1) over the main roller (2), over the platen (3), over the front roller (4) and then to the front spindle (5).
38
NOTE:
The above illustration shows the substrate loaded with the printed face outwards on both input and output rolls. You can also load substrate with the printed face inwards on either or both rolls, in which case the spindle will turn in the opposite direction. The printer asks you for the winding direction if it cannot detect it automatically.
Each of the spindles has its own motor. The motors maintain tension on the substrate. Some vacuum is applied at the level of the platen to keep the substrate flat. The substrate is moved forwards by the drive roller motor, on which there is a pinch mechanism to stop the substrate from slipping. The pinches must be up when moving the carriage beam, and down when printing or checking the substrate, otherwise a message is displayed. The accuracy of the advance is controlled by the substrate-advance sensor, or, for substrates that the sensor cannot see, by tracking the main roller movement.
Before loading a roll into the printer, you must have a roll loaded onto a spindle (the input roll) and an empty core loaded onto another spindle (the output roll). See
Load a roll onto the spindle on page 33 .
Chapter 3 Handle the substrate ENWW
NOTE:
For the output roll, use a single empty core the same length as the input core. Do not place two or more shorter cores on the same spindle, which could cause substrate-advance problems.
TIP:
The spindle by itself is quite heavy, and a roll of substrate can be much heavier. You are recommended to use a forklift or some other equipment to move it into position; otherwise, lift one end into the printer, and then the other end.
1.
Go to the HP Internal Print Server and select Substrate > Load/Unload, then select the correct configuration.
2.
Remove the substrate edge holders in the print platen, or move them aside, so that they do not get in the way while loading the substrate.
CAUTION:
Loading the substrate on top of the edge holders could severely damage the printheads and carriage.
3.
Lift the substrate pressure handles at the rear of the printer.
ENWW
4.
Go to the front panel and select Carriage beam position > Move to highest position.
The printer raises the carriage beam, making it easy to insert the substrate. This process takes about two minutes to complete. During this period, you can load the input and output rolls.
NOTE:
While the carriage beam is rising, you can stop it by pressing the Cancel key.
TIP:
If you use the Substrate loading tool, you do not need to raise the Carriage beam.
5.
Bring the new roll on its spindle to the rear of the printer, with the geared end of the spindle on the left.
6.
Rest the ends of the spindle on the platforms provided at the rear of the printer; plastic pads are provided to absorb the impacts.
Load a roll into the printer
39
7.
Open the latches at both ends of the spindle (if they were closed) and push the roll on its spindle into the printer.
8.
Close the latches to secure the spindle in place.
TIP:
If you cannot close the gear side latch, try sliding the spindle towards the side plate to make sure the end flange is not sitting on the bearings.
9.
In the same way, load the spindle with the empty core into the front of the printer. In this case, the geared end of the spindle should be on the right.
10.
Check that the printer has finished raising the carriage beam.
11.
Check that the curing plates are in the correct position for the substrate you are loading (see
The curing plates on page 32 ).
12.
Pass the leading edge of the substrate through the printer to the output roll.
40 Chapter 3 Handle the substrate ENWW
ENWW
13.
Once in front of the printer, if you find that you haven't unrolled enough substrate, select Start
main roller motion from the front panel to unroll some more. The substrate unrolls only when you pull it.
14.
If you are loading a vinyl substrate on an LX850 printer, you are recommended to use the output diverter from the ink collector kit, to minimize wrinkles.
15.
At the rear of the printer, measure the distance between the printer's left side plate and the left edge of the substrate. This distance should be at least 145 mm (5.7 in), otherwise the edge of the substrate may go out of the print zone and start touching the printer covers.
16.
At the front of the printer, the right edge of the substrate on the empty core should be at the same distance (A) from the right side plate as the distance measured on the input side.
NOTE:
When loading non-elastic substrates, a difference of 2-3 mm (0.01 in) between the measurements from the rear side plate and front side plate may be acceptable without problems of skew or wrinkles.
Rear Front
TIP:
It is important that tension is uniform across the width of the substrate. One way of achieving this is to take the front substrate edge by its center and shake it alternately to right and left several times while at the same time pulling the substrate until it reaches the core on the output spindle.
17.
When the substrate is evenly tensioned, attach it to the empty core with adhesive tape. Tape it first in the center, and then at the left and right sides, making sure not to pull the substrate excessively or leave it wrinkled.
Load a roll into the printer
41
18.
Go to the front panel and select Carriage beam position > Move to printing (normal) to lower the carriage beam into its normal position, close to the substrate. This process takes about two minutes to complete.
NOTE:
The Move to printing (custom) position allows you to set the printhead-to-substrate distance for thick substrates or substrates that may wrinkle in the print zone, to avoid ink smearing.
Be aware that raising the printhead from the substrate may give poorer print quality.
WARNING!
Do not insert your hands or anything else into the printer while the carriage beam is descending.
19.
Lower the substrate pressure handles at the rear of the printer. If you forget to do this, an alert will remind you.
20.
If you intend to use full bleed, do not use the substrate edge holders, but use Move to printing
(custom) to raise the carriage. Do not remove the edge holders; just move them aside at each end of the platen.
21.
If you do not intend to use full bleed, use the substrate edge holders to prevent the substrate edges
from lifting up and jamming while printing. See The substrate edge holders on page 27
.
22.
Go to the HP Internal Print Server and press the Load button. The printer rotates both rolls to check their diameters, and it also checks the width of the roll, the winding direction, the vacuum and the substrate advance calibration (this takes 1–2 min).
NOTE:
Some substrates (such as transparent substrates) cannot be measured by the printer in this way. In such cases, you will be asked to enter the required information manually. Use the scale on the curing module to see the value for the right-hand edge that must be entered manually in the HP Internal Print Server.
42 Chapter 3 Handle the substrate ENWW
23.
In the HP Internal Print Server, choose from the list of substrate types the type that you have loaded.
The contents of the Loaded Substrate window are determined automatically when the substrate is loaded and checked. However, if the printer is unable to detect the edges of the substrate (for instance, in the case of a transparent substrate), you will have to measure the distance of the left edge from the printer's side plate, and complete the Left Edge and Width fields yourself.
For more information on when you might want to change the carriage beam position, see
An alert regarding substrate advance tracking may appear at this point. For more information on
and the Maintenance and troubleshooting guide.
The printer is now ready to print.
Load a roll (dual roll-to-roll configuration)
The two substrate rolls are mounted on the rear dual-roll spindle and will be collected on the front dualroll spindle. The substrate goes from the rear spindle over the main roller, over the platen, over the front roller and then to the front spindle.

18.
Unlock the differentials on the input and output spindles.
19.
Go to the front panel and select Carriage beam position > Move to printing (normal) to lower the carriage beam into its normal position, close to the substrate. This process takes about 2 minutes to complete.
NOTE:
The Move to printing (custom) position allows you to set the printhead-to-substrate distance for thick substrates or substrates that may wrinkle in the print zone, to avoid ink smearing.
Be aware that raising the printhead from the substrate may give reduced print quality.
WARNING!
Do not insert your hands or anything else into the printer while the carriage beam is descending.
NOTE:
If you are printing on a heavy roll, such as Self Adhesive, in order to reduce the risk of substrate jam, we recommend adding an output diverter and increasing the vacuum level.
20.
Go to the HP Internal Print Server and press the Load button. The printer rotates the rolls to check their diameters, and it also checks the width of the roll, the winding direction, the vacuum and the substrate advance calibration (this takes 1–2 min).
NOTE:
Some substrates (such as transparent substrates) cannot be measured by the printer in this way. In such cases, you will be asked to enter the required information manually. Use the scale on the curing module to see the value for the right-hand edge that must be entered manually in the HP Internal Print Server.

21.
In the HP Internal Print Server, choose from the list of substrate types the type that you have loaded.
The contents of the Loaded Substrate window are determined automatically when the substrate is loaded and checked. However, if the printer is unable to detect the edges of the substrate (for instance, in the case of a transparent substrate), you will have to measure the distance of the left edge from the printer's side plate, and complete the Left Edge and Width fields yourself.

The printer is now ready to print.
Load a roll (roll-to-free-fall configuration) (LX850 only)
The substrate roll is mounted on the rear spindle; the printed substrate will be deposited on the floor in front of the printer. The substrate goes from the rear spindle (1) over the main roller (3), over the platen, over the front roller (5) and then to the tension roller (7), after which it continues to the floor. The diverter rollers (2 and 6) and the ink collectors (4) are installed when printing on porous substrates.
48 Chapter 3 Handle the substrate ENWW
NOTE:
You can load substrate with the printed face inwards or outwards on the spindle, in which case the spindle will turn in the opposite direction. The printer asks you for the winding direction if it cannot detect it automatically.
Before loading a roll into the printer, you must have a roll loaded onto the input spindle. See
Load a roll onto the spindle on page 33 .
TIP:
The spindle by itself is quite heavy, and a roll of substrate can be much heavier. You are recommended to use a forklift or some other equipment to move it into position; otherwise, lift one end into the printer, and then the other end.
1.
Go to the HP Internal Print Server and select Substrate > Load/Unload, then select the correct configuration.
2.
Remove the substrate edge holders in the print platen, or move them aside, so that they do not get in the way while loading the substrate.
CAUTION:
Loading the substrate on top of the edge holders could severely damage the printheads and carriage.
3.
Lift the substrate pressure handles at the rear of the printer.
ENWW
4.
Go to the front panel and select Carriage beam position > Move to highest position.
The printer raises the carriage beam, making it easy to insert the substrate. This process takes about 2 minutes to complete. During this period, you can load the input roll.
NOTE:
While the carriage beam is rising, you can stop it by pressing the Cancel key.

NOTE:
The tension roller lever should always be raised unless the tension roller is in use.
Chapter 3 Handle the substrate ENWW
11.
Pass the leading edge of the substrate through the printer, over the main roller and the front roller to the tension roller.
12.
Once in front of the printer, if you find that you haven't unrolled enough substrate, select Start
main roller motion to unroll some more. The substrate unrolls only when you pull it.
TIP:
When passing the substrate's leading edge behind the tension roller, it is important to have no excess substrate between the front roller and the tension roller, although you can leave excess substrate before the front roller at this stage. Once the leading edge has been passed behind the tension roller, you can roll a stiff substrate downwards at the front roller or pull a flexible substrate from under the tension roller through the holes provided in the substrate guide around the roller.
ENWW
13.
At the rear of the printer, measure the distance between the printer's left side plate and the left edge of the substrate. This distance should be at least 145 mm (5.7 in), otherwise the edge of the substrate may go out of the print zone and start touching the printer covers.
14.
At the front of the printer, the right edge of the substrate on the tension roller should be at the same distance (A) from the right side plate as the distance measured on the input side.
NOTE:
There is a square indentation in the right side plate in front of the tension roller. You should measure the distance between the substrate edge and the inside of this indentation.
NOTE:
When loading non-elastic substrates, a difference of 2-3 mm (0.01 in) between the measurements from the rear side plate and front side plate may be acceptable without problems of skew or wrinkles.

15.
When the substrate edge is correctly positioned and the substrate is evenly tensioned, lower the tension roller lever.
16.
Go to the front panel and select Carriage beam position > Move to printing (normal) to lower the carriage beam into its normal position, close to the substrate. This process takes about 2 minutes to complete.
NOTE:
The Move to printing (custom) position allows you to set the printhead-to-substrate distance for thick substrates or substrates that may wrinkle in the print zone, to avoid ink smearing.
Be aware that raising the printhead from the substrate may give poorer print quality.
WARNING!
Do not insert your hands or anything else into the printer while the carriage beam is descending.

This configuration is similar to the roll-to-free-fall configuration, but with the addition of a collector roller and loop shaper.
The following illustration shows a completed configuration with a single roll of porous substrate, so the ink collector kit has been installed.
54
TIP:
Do not try to load or unload the collector while printing.
Before starting to load the substrate, select a loop shaper of the correct length to match the substrate width. The following tubes are supplied so that you can make up loop shapers of many different lengths.

1.
Follow the whole loading procedure for the roll-to-free-fall configuration.
2.
Load an empty substrate core onto the collector spindle. For dual-roll printing, load two cores of the same diameter onto a single spindle (it is not recommended to use a dual-roll spindle as the collector).
3.
Use the buttons on the front panel to advance the substrate's leading edge until it reaches the core on the collector.
4.
Tighten the substrate so that it is evenly tensioned, then attach the leading edge to the core with tape, first at the center and then at the sides. There should be no wrinkles or slackness across the substrate.
5.
Use the buttons on the front panel again to advance the substrate so that a substrate loop is produced between the tension roller and the collector.
6.
Place the loop shaper into the substrate loop.
ENWW
NOTE:
Loop detection is done on the right-hand side of the printer; so avoid putting your foot or any other object under the collector on the right-hand side.
7.
Go to the HP Internal Print Server and press the Enable collector button.
8.
Select the winding direction: Outwards is recommended, as it permits an output roll up to 230 mm (9 in) in diameter. If you select Inwards, the diameter of the output roll is limited to 150 mm
(5.9 in).
NOTE:
The winding direction cannot be changed on the fly: the collector has to be deactivated and reactivated.

Load a roll with the 'Substrate Loading Tool'
The Substrate loading tool enables you to load a substrate into the printer quicker as the Carriage
Beam does not need to be raised. In the example described here the substrate is loaded through the path, but the tool can also be used to load the substrate through the Roll-to-free-fall configuration.
1.
Use the buttons on the front panel to advance the substrate's leading edge until it reaches the ground.
2.
On the loading tool are substrate flaps held with magnets, open the flaps and insert the leading edge of the substrate into the flaps.

Double-sided printing
Selecting the double-sided printing option will provide you with guidance and help specific to doublesided printing during the load process.
The roll-to-roll configuration is recommended for double-sided printing. You cannot perform doublesided printing if the dual-roll spindle or the ink collector kit is in use.
A double-sided job must be defined as a pair of images.
●
Side A is the first image to be printed.
●
Side B is the second image to be printed, on the reverse of Side A.
On Side A, after each row of images a black continuous line called a “registration line” is automatically printed: (a) and (b) below. These registration lines are used while printing Side B to minimize any registration errors in the direction of substrate movement.
When the whole of Side A has been printed, a space (c) is normally left blank for calibrations (the substrate is already warmed up), and a further space (d) is left blank so that the substrate can be loaded for printing Side B. However, these blank spaces are optional: you can turn them off.

View information about the substrate
Information about the loaded substrate is displayed at the bottom of the main screen of the HP Internal
Print Server.
To see more information, select the Substrate menu and then Settings.
Substrate presets
Each supported substrate type has its own characteristics. For optimum print quality, the printer changes the way it prints on each different substrate type. For example, some may need more ink and some may require higher temperatures for drying and curing. So the printer must be given a description of the requirements of each substrate type. This description is called a substrate preset. The printer is supplied with substrate presets for some specific substrate types, and also with presets for some generic types. Each generic preset comes in three variations: with 100%, 150%, and 250% ink density.
As it is inconvenient to scroll through a list of all substrate types available, your printer contains substrate presets for only the most commonly used substrate types.
For your convenience, substrate settings from many substrate vendors have been collected at http://www.hp.com/go/LX850/solutions/ and http:// www.hp.com/go/LX820/solutions/ . You can check substrate availability using the Media Finder application that you will find there.
To install a new substrate preset that you have downloaded, go to the HP Internal Print Server and select Substrate > Presets management.

Create a new substrate preset
Whenever you load a new substrate type into your printer, you must choose a substrate preset for it.
1.
If possible, select a preset for the specific substrate type that you intend to load.
2.
If no specific preset is available, select a generic preset that corresponds to the specific type that you intend to load. You may be able to get better results by creating a specific preset for your substrate type.
3.
If no specific nor generic preset matches your substrate, select whatever preset seems to resemble it most closely. You will probably get better results by creating a specific preset for your substrate type.
Creating a new preset has several purposes.
●
You can assign a name of your own choice to a particular substrate.
●
You can adjust the preset to suit the precise characteristics of your substrate.
●
You can adjust the preset to your intended use of the substrate, which may range from highestquality printing to fast production output.
NOTE:
You can change only the presets that you have created yourself. The presets supplied by HP cannot be changed.
Before creating a new preset, it is useful to understand a little about how the printer works. Here are some of the available settings.
Table 3-1 Substrate preset settings
Setting
Number of passes
The number of passes specifies how many times the printheads will print over the same area of substrate.
Curing temperature
Curing is needed to coalesce the latex, creating a polymeric film which acts as a protective layer, while at the same time removing the remaining co-solvents from the print. Curing is vital to ensure the durability of the printed images.
Drying temperature
The heat applied in the printing zone removes water and fixes the image to the substrate.
If too low
The printer cannot deposit enough ink over a given area, so colors are muted.
Because larger substrate advances are required and ink has to be placed faster on the substrate, the boundaries between passes are more visible and may be seen as horizontal lines across the image. However, printing speed is relatively high.
The print may emerge not fully dry, so that the ink smears when rubbed with a finger. The print may appear dry immediately after printing and then become wet to touch some seconds later. If the curing temperature is very low, the latex film is not created, in which durability is drastically reduced.
Print quality defects such as bleeding and coalescence may occur. Boundaries between colors are not well defined.
Single-color area fills are not uniform: ink is concentrated at the edges or in clusters within the area fill.
If too high
Colors are vivid, print quality is high, and printhead health is well maintained.
However, printing speed is relatively low.
The substrate may wrinkle on the platen, causing vertical banding or ink smears, with substrate jams in extreme cases.
Fragile substrates may be damaged.
Thermal marks may be seen on the substrate; they may appear as vertical bands in some colors. The substrate may wrinkle on the platen, causing vertical banding or ink smears, with substrate jams in extreme cases.
64 Chapter 3 Handle the substrate ENWW
Table 3-1 Substrate preset settings (continued)
Setting
Substrate tension
Tension is applied at the input and the output side. It needs to be evenly distributed along the whole width of the substrate, thus substrate load is a critical operation.
TIP:
Input tension should be higher than output tension.
If too low If too high
The substrate may be poorly wound onto the output roll, with sagging and skew, in which case it is likely to become increasingly wrinkled in the printing zone. Also, substrate advance could be irregular, resulting in horizontal bands.
The substrate may be permanently deformed or damaged.
TIP:
Output tension should be increased whenever vacuum pressure is increased.
Airflow power
The airflow generated by the fans in the curing module is split into two air layers, one reaching the print zone and the other at the end of the curing zone. This is needed to help remove the moisture and co-solvents while the substrate is being heated by the drying and curing modules.
Vacuum pressure
The printer will be less able to dry the ink. In certain printing conditions (fast print modes with fewer than 5 passes and ink densities below 150%), there could be print-quality defects such as bleeding and coalescence and/or incomplete drying of the prints.
The substrate can lift up off the platen and touch the printheads. This can smear the printed image, cause a substrate jam or even damage the printheads.
The vacuum applied to the substrate in the printing zone helps to hold the substrate down on the print platen, keeping the distance to the printheads constant.
Ink restrictions
A way of specifying the maximum amount of each color of ink that can be laid down on the substrate.
Carriage beam position
The distance between the printing heads and the substrate is a critical determinant of print quality. It can be adjusted by modifying the height of the carriage beam above the platen.
Some colors may be too pale.
The substrate may touch the printheads.
This can smear the printed image, cause a substrate jam or even damage the printheads.
With certain substrates and printing conditions, an excessive airflow in the print zone could cause print-quality defects such as vertical banding. Also, with some substrates, too high an airflow could prevent the printer from reaching the drying and/or curing target temperatures, causing potential system power errors.
Vertical bands can appear in some colors. Also, for sticky substrates, friction could be too high and substrate advance irregular, resulting in horizontal bands.
The print may suffer from coalescence, wrinkles and insufficient curing, depending on the substrate and the other settings.
Print quality defects such as graininess, shadows and worm-shaped dark areas may occur.
Prepare the printer for a new substrate
1.
Whenever possible, try to ensure that your printer is in an optimum state before you create a new preset: run any pending maintenance task, in particular printhead checks and alignment.
2.
Stop the print queue and wait for the printer to finish the current job. No jobs should be sent to the printer until the new substrate preset is complete.
3.
Load your new substrate. The process of loading a substrate into the printer has been designed to be completely independent of the substrate type. When loading, follow the correct procedure and ensure that the roll width is specified, either automatically by the printer or by yourself. You may
ENWW
Create a new substrate preset
65
not experience the best possible results if there are significant differences between the specified and the actual roll width.
NOTE:
You are recommended to use the roll-to-roll configuration when creating a new preset.
4.
Choose a suitable carriage beam printing position: see
Set the carriage beam position on page 25 .
Create and name the new preset
To create a new preset, you must copy an existing preset, then rename and modify it.
1.
Select Substrate > Create in the HP Internal Print Server.
2.
Choose a name for your substrate.
66
TIP:
To avoid confusing other users, it is a good idea to use the substrate's commercial name.
TIP:
If you plan to use more than one ink density with this substrate, or more than one number of print passes, include the ink density and/or number of passes in the name.
Chapter 3 Handle the substrate ENWW
3.
Select the parent substrate. Show details can help you to choose one that's similar to the new substrate. If you choose a generic substrate, select the ink density according to the expected behaviour and applications for your substrate.
TIP:
Use 100% ink density for substrates such as PVC Scrim Banner Frontlit, Green Banner,
Vinyl-Calendared, Vinyl-Cast, Blue back and Scrim banner.
TIP:
Use 150 or 250% ink density for substrates such as PVC Scrim Banner Backlit, Perforated
Vinyl, Polyester Film, Polyester Fabric, Canvas Polyester and Tyvek.
4.
You can now press the Create button to create a new entry in the substrates list, in the Custom
substrates category, with all its characteristics inherited from the parent substrate. Press Finish if you do not plan to modify any substrate setting for now.
Consider how you plan to use your new substrate. If you require high-quality printing, you will need more passes; if you require fast printing, you will need fewer passes. Make a list of the print modes you are most likely to use.
Fine-tune the settings in your new preset
In the Settings pane you can modify various settings used in the printing process.
NOTE:
The changes in the Settings pane apply only to the highlighted print mode, so you must adjust each print mode independently. Any setting you have changed is indicated by an asterisk (*).
1.
Select the number of print passes that you want to use. Color calibration uses six passes with
100% ink density, eight passes with 150% ink density, or fourteen passes with 250% ink density.
You are recommended to create a preset suitable for color calibration; for normal printing, you may want to create other presets with different numbers of passes.

Press the Print test button with the printer adjustments inherited from the parent substrate. Look for any potential problems during printing, such as:
●
Potential head crashes or ink smears between the carriage and the substrate. Cancel the job and/or turn off the printer if necessary to avoid damaging the printheads or any other sensitive printer components.
●
Potential substrate deformation and/or wrinkles caused by too much heat.
TIP:
In order to see better what is happening in the printing area, stand behind the printer, and look towards the print platen through the pinch wheels: you will find it easy to see wrinkles, risk of ink smearing or substrate deformation.
3.
Wait five minutes after the last part of the sample emerges from the printer.
4.
Evaluate the sample, directly from the output area:
68 Chapter 3 Handle the substrate ENWW
●
Brush your fingertip over the full squares in the upper part of the sample to check that the ink is dry and firmly bonded to the substrate.
●
Look for coalescence problems in the middle part of the sample (see the Maintenance and
troubleshooting guide).
●
Look for ink bleeding problems in the lower part of the sample (see the Maintenance and
troubleshooting guide).
You are recommended to check the sample for problems and make adjustments to the settings in the following sequence. After making any adjustment, reprint the sample to see the current situation.
ENWW
1.
If an alert tells you that the substrate advance cannot be tracked automatically with the current substrate, select Substrate > Settings and set the Automatic tracking (OMAS) field to Off. You will need to adjust the substrate advance manually (see the Maintenance and troubleshooting

When you have adjusted the settings for one print mode, you can proceed to other print modes.
However, it's not necessary to deal with them all at once: you can edit the substrate preset at any time by selecting Substrate > Edit in the HP Internal Print Server.
TIP:
Note the settings that you used with the first print mode. You can probably use the same settings for other modes.
There is also a possibility to change the different settings while printing (in case the substrate preset selected is a custom one). This can be done while printing, click the Print Adjustment button, and then the different settings can be fine-tuned. Note that some changes might take some time to have an impact (for example: increases or decreases in temperature).
Chapter 3 Handle the substrate ENWW
Adjust the printing workflow for optimum color performance
1.
Check your substrate's color calibration status and calibrate it if recommended, by selecting
Substrate > Color calibration in the HP Internal Print Server. See the 'Printer calibration' chapter in the Maintenance and troubleshooting guide for more information.
2.
Create ICC profiles for your substrate; see your RIP documentation for instructions. Normally, the procedure includes setting the total ink limit as well as creating the profiles. When setting the total ink limit in the RIP, bear in mind the basic problems to be avoided: ink bleeding and coalescence, and damp prints caused by incomplete curing.
Export your new preset and profiles
Your substrate has been fully characterized from both the printer and the RIP points of view: a substrate preset is present in the printer, and one or more ICC profiles are present in the computer hosting your
RIP. To export the ICC profiles, see your RIP documentation. To export your substrate preset, go to the
HP Internal Print Server and follow these steps:
1.
Select Substrate preset management.
2.
Select the Export tab. A file with the extension oms will be saved, which can be imported by another printer.
To import your substrate preset into another printer:

4 Handle the ink system
Ink system components
Ink cartridges
Ink cartridges store the ink and are connected to the printheads, which deposit the ink on the substrate.
You can purchase ink cartridges for your printer, see
How to order supplies on page 80 .
CAUTION:
Observe precautions when handling ink cartridges because they are ESD-sensitive devices (see the
). Avoid touching pins, leads and circuitry.
Each cartridge contains 3 liters of HP Latex Ink, which requires no special ventilation and creates no hazardous waste. The cartridge consists of a bag contained in a recyclable cardboard box.
Printheads
The printheads take ink from the ink cartridges and deposit it on the substrate. You can purchase
printheads for your printer, see How to order supplies on page 80 .
74 Chapter 4 Handle the ink system ENWW
CAUTION:
Observe precautions when handling printheads because they are ESD-sensitive devices
(see the
Glossary on page 106 ). Avoid touching pins, leads and circuitry.
The printer's six-color writing system uses three dual-color printheads with a total of 31,680 nozzles
(5,280 per color).
Printhead cleaner roll
The printhead cleaner roll is a roll of absorbent material used to clean surplus ink from the printheads after each pass over the substrate.
To change the printhead cleaner roll when necessary, see the Maintenance and troubleshooting guide.
A new roll is provided in the Maintenance Kit (see
How to order supplies on page 80 ).
TIP:
You should not touch the printhead cleaner roll except when you need to replace it. Any interference with the roll may prevent the printer from keeping track of roll usage, in which case you may see spurious error messages, and a printing job may be cancelled unnecessarily.
Aerosol filters
The printheads produce many fine droplets of ink, most of which are placed accurately on the substrate. However, a small proportion of these droplets escape sideways; the two aerosol filters are placed on either side of the printhead carriage to intercept them.
To change the filters when necessary, see the Maintenance and troubleshooting guide. New filters are provided in the Maintenance Kit (see
How to order supplies on page 80 ).
Ink deposits
In order to check the status of the printhead nozzles, the printer expels a few drops of ink from each nozzle of each printhead into the ink deposits. This is done at the start of each print job, whenever a printhead is replaced, and whenever you request a printhead check from the HP Internal Print Server.
To clean the ink deposits when necessary, see the Maintenance and troubleshooting guide.
How to work with ink system components
Remove an ink cartridge
An ink cartridge should be removed and replaced when it is empty or past its expiry date. An empty cartridge is indicated in the HP Internal Print Server and by an orange blinking light beside the cartridge itself. You may also decide to remove a cartridge if it contains little ink and you want to provide for a long period of unattended printing.
The printer can continue printing without any ink cartridges for at least 20 minutes, depending on the print mode and the job being printed. Therefore, cartridges can be replaced while printing continues. A functional ink cartridge is required in order to start a new job.
1.
Go to the cartridge that you intend to remove. The black, yellow and cyan cartridges sit at the front of the printer; the magenta, light magenta and light cyan cartridges are at the rear.

4.
Put the new cartridge into its correct place on the printer. The black, yellow and cyan cartridges sit at the front of the printer; the magenta, light magenta and light cyan cartridges are at the rear.
5.
Check that the rubber part around the needle in the cartridge connector is clean. Clean gently if necessary.
Chapter 4 Handle the ink system ENWW
6.
Connect the cartridge connector to the cartridge.
NOTE:
The cartridge connectors will refuse connection to the wrong type or color of cartridge. If you cannot connect the connector easily to the cartridge, please check that you have the correct cartridge.
7.
Ensure that the side buttons on the cartridge connector are in the 'out' position, showing successful connection.
8.
A few seconds after you have connected the cartridge, the green LED should be lit. If it is not lit after 10 seconds, please reconnect the cartridge. The LED will turn red if the supply is expired or not valid; please refer to the HP Internal Print Server or to the front panel for further details and corrective action.
Remove a printhead
If a printhead develops an electrical fault or overheats, the HP Internal Print Server will indicate that it should be reseated or replaced. In addition, you may wish to replace a printhead if its warranty has expired or if you feel that its performance is not adequate.
1.
Ensure that the printer is not trying to print: stop the job queue.

Manage print jobs
Add a job from the RIP
When the RIP has generated a print job, its output folder will contain at least three files:
●
An XML file containing job settings
●
A low-resolution TIFF file for use in previews
●
At least one high-resolution TIFF file containing the image to be printed
The output folder should be the shared folder on the HP Internal Print Server computer that was created during printer installation. The HP Internal Print Server cannot take files directly from the network because access would not be fast enough.
1.
Go to the HP Internal Print Server.
ENWW
Manage print jobs
83
2.
Select the Add New Job icon or File > Add New Job. Navigate across the network to the folder containing the print job files, and click Open to import the job into the HP Internal Print
Server.
3.
The next dialog box displays information about the job.
84
You can change the default job name the first time you open its properties window. Once you save the job name, it cannot be changed. Use the Save As button to create a copy of an existing job with a different name.
Although you can change the substrate and print mode from this window by using the Change button, you are recommended not to do so, because it may adversely affect print quality. It is better to make such changes from the RIP.
The Job Info tab can be used to select annotations and special marks to be printed alongside the image.
The Job Notes field can be used to add some text to be printed in the bottom of each copy with the annotations, if any.
4.
Click the Save button to store the job in the HP Internal Print Server for further processing.
Chapter 5 Printing options ENWW
Rotate a job
A job can be rotated by 90 degrees in either direction by using the rotation icons at the top right of the
Job Properties window.
NOTE:
Rotation is available only when the printer is not printing.
The effect of rotation is shown in the preview. After you press the Save or Save As button in the Job
Properties window, the actual rotation of the job takes place. This could take a few minutes, depending on the image size and resolution, during which the job can be neither printed nor edited, and the job status is shown as Rotating. When it is done, the job is ready for printing.
Manage the print queue
The main screen of the HP Internal Print Server displays the queue of print jobs and various icons that can be used to manage the queue.
ENWW
Manage print jobs
85
86
Above the print queue are the following icons:
●
Add New Job : See
Add a job from the RIP on page 83 .
●
Add Existing Job : Return a job to the queue that has been printed already. Printed jobs remain available unless deleted manually.
●
Edit Job : Edit the properties of a job in the queue.
●
Proof : Proof a job in the queue (not available for nested jobs). This can be used to crop the image before printing.
●
Activate : Activate a job in the queue.
●
Hold : Hold a job in the queue.
●
Up : Select the next job upwards in the queue.
●
Down : Select the next job downwards in the queue.
●
Remove : Delete the selected job from the queue.
To the left of the print queue are the following buttons:
●
Single: If this is pressed, you can select and print only one job at a time. You can request multiple copies of it.
●
Queue: If this is pressed, all listed jobs are queued for printing.
●
Print Job/Print Queue: Prints a single job (if Single has been pressed) or the whole queue (if
Queue has been pressed).
Chapter 5 Printing options ENWW
●
Abort: Stop printing the current job immediately. The job status changes to Finishing, and the printer will dry the partially-printed job before continuing with the next job in the queue.
If you press Abort again, the drying process also stops, and the queue is halted.
●
Print adjustment: Display the substrate-advance compensation (which can be changed).
●
Settings: Display information on the loaded substrate.
●
Rows to Register: This option enables you to choose which registration lines are scanned by the printer. If you select 1 (the default), the printer stops printing and checks every registration line.
If you select 2 (for example), the printer scans every second registration line, which increases the printing speed, but also slightly increases the chances of misregistration. If you select 0 (zero), the printer does not scan the registration lines.
TIP:
You may need to select 0 if the substrate advance sensor cannot detect the registration lines, in which case a system error 78.7:01 is displayed.
Delete a job
This is the correct procedure to delete a job.
1.
Remove the job from the queue by using the Remove icon or by right-clicking the file and selecting the option Remove. When deleting a job in this way, the files may or may not be left on the printer's hard disk, and the file may or may not still be available from the list in the Add
Existing Job window, depending on the settings in Tools > Preferences > Queue Rules, in the section “When removing jobs from the queue”.
2.
Remove the job with File > Delete job, select the job and press the Delete button. Now the file cannot be retrieved from the Add existing job window.
Layout method
The Job Properties window is displayed when you import a job into the HP Internal Print Server, or when you right-click the job queue in the HP Internal Print Server.
This window contains a Method list that allows you to choose among the following alternatives:
●
Simple: one or more copies of a single job are printed on the substrate one after the other, each copy below the previous one. You can specify the vertical gap between successive copies of the same job.
●
Step and Repeat: multiple copies of a single job are printed one after the other, across the width of the substrate if there is room. See
.
●
Tiling: a single job is printed in sections, to be put together later. See
●
Nesting (Multi-image): the selected jobs are printed one after the other, across the width of the substrate if there is room. You can use the Advanced Nesting Arrangement window to alter the layout manually. See
All layout methods give you the opportunity to define a left margin that will be left blank, or to center your jobs on the substrate so that there is an equal amount of white space on both sides.
All layout methods can be used with dual-roll printing. In this case, the software will warn you if your layout involves printing in the gap between rolls; but it will allow you to do it if you disregard the warning.
ENWW
Layout method
87
Step and Repeat
Step and Repeat is a layout method that allows you to print multiple copies of a job side by side across the width of the substrate, if there is room.
This method has the following options:
●
Steps: the number of copies to print horizontally, across the width of the substrate.
●
Step gap: the horizontal gap between copies.
●
Repeat gap: the vertical gap between copies.
●
Fit Substrate Width: if this option is checked, the number of steps will be set to the maximum that will fit into the substrate width.
The Repeats field (the number of rows of copies to be printed) is calculated automatically and cannot be altered directly.
Tiling
Tiling is a layout method that allows you to print a large image in sections, and then put the sections together later.
88 Chapter 5 Printing options ENWW
This method will automatically cut your image into sections and print the sections separately. There are two alternative ways to select the size of the sections:
●
Select the width and height of each section. The number of sections is then calculated automatically.
●
Select the number of horizontal and vertical sections. The width and height of each section is then calculated automatically.
If you choose a non-zero overlap, the size of each section will be increased by that amount so that the printed sections will overlap when put together.
If you have requested multiple copies, you can specify the vertical gap between copies.
The drop-down list at the top of the preview field allows you to preview all sections or just one of the sections to be printed.
Double-sided
Double-sided printing helps you to print rows of images on both sides of the substrate.
●
Double-sided printing functionality is a process to guide you when printing a substrate in both sides.
●
Double-sided printing can be used to print the same image or different images in each side.
●
The functionality automatically compensates for any registration errors, of the position of the plot, along both axes (along the substrate width + substrate advance) to minimize any errors.
●
Select double-sided printing when printing a single roll of a non-porous substrate, using LX610 inks only.
ENWW
Layout method
89
NOTE:
Neither the dual-roll spindle nor the ink collector kit can be used with this option.
●
Even though double-sided printing uses the same substrate, each side must be considered as printing on different substrates due to the different mechanical properties. This is the main reason why calibrating each side of the substrate is highly recommended; and it can be done easily.
NOTE:
The images of Side A and Side B must have approximately the same dimensions. The image that you select for each side must be the same image for the entire side.
Create a job
Any image created in the RIP can be printed in either side A or side B, without any special requirements. However, side A and side B must have the same dimensions when printed on the substrate.
NOTE:
In order to minimize registration errors on some substrates, you are recommended to compensate for substrate contraction in the RIP when the image is generated.

Center: All layout methods give you the opportunity to define a left margin that will be left blank, or to center your jobs on the substrate so that there is an equal amount of white space on both sides.
NOTE:
To compensate for any possible registration errors that may occur, centering the images is highly recommended.

every Image Registration Line, if you select a higher number, for example 2, the printer only scans every second Image Registration Line. This increases the speed of the job, but also slightly increases the chances of misregistration.
◦ Rotate: This option enables you to rotate the image 180 o
.
2.
In the Layout tab are the following options, we recommend using these options when printing double-sided:
●
Side B calibration space: When this check box is selected the printer leaves an area of substrate empty after the images have been printed (the substrate is warmed-up), this is to give space to perform certain calibrations on side B that are recommended, such as the
Dynamic Color Registration and the Substrate Advance Compensation. At the end of the empty space a dotted line is printed.
●
Side B loading space: When this check box is selected the printer will advance the substrate so that there is sufficient substrate to load side B.
Preview (Image/Layout/Preview both)
There are three different previews:
1.
Click the Image button and preview the selected images.
2.
Click the Layout button and preview how the printer will print each side.
92 Chapter 5 Printing options ENWW
3.
Click the Preview both button to see a simulation of how both images will print on side A and on side B. You can use this simulation preview to check that the orientation of the images relative to each other is how you expect the finished result to be.
1.
Select Side A from the drop down menu
2.
Select Save or Save As.

93
The number of copies will be automatically distributed according the parameters defined in the step
Define double-sided job on page 90 (number of rows, column, centered). .
●
At the end of each row a black registration line will be printed automatically (a). This registration line will be used while printing the side B, to position the side B rows and minimize the registrations errors.
●
It is recommended to mark with a marker the back side of the last Image Registration Line (b) to position the substrate during the side B loading process.
●
When the side A has been printed, after the last continuous black registration line, the printer will automatically provide an area to perform the side B calibrations (c) and side B loading
(d) area.
94
NOTE:
The area dedicated to calibrations, between the continuous registration line and the dotted line (c), must be advanced at the same speed as the printed area, and at the same temperature, to ensure an effective calibration.
4.
When Side A has finished printing, unload side A, refer to
Chapter 5 Printing options ENWW
5.
Check that the optical advance sensor is clean, do not hesitate to clean it, refer to the
Maintenance & Troubleshooting Guide -> Hardware Maintenance -> Clean the substrate-advance sensor.
6.
Load Side B refer to Side B: Load and print on page 61
NOTE:
For accurate printing we recommend that Substrate Edge Detection is selected.
7.
When Side B is loaded perform the following, for more details of these procedures refer to Side B:
a. Align the dotted line with the platen
b. Perform the calibrations (advance calibrations and dynamic color registration, refer to the
Maintenance & Troubleshooting Guide).
c.
Select Side B from the drop menu.
d. Ensure that the Image Registration Line is aligned with the platen and start printing side B.
e. Configure Rows to register, refer to
Define double-sided job on page 90 .
f.
Select save or save as.
g. Select Print Job and print the selected image.
While printing Side B the printer will automatically read each registration line and Side B will be positioned to minimize the registration errors
NOTE:
To activate the side you want to print, always select it from the drop down menu first, make any changes to the image and select save.
ENWW
NOTE:
If you select Print Job and the printer cannot detect the Image Registration Line, refer to the Maintenance and Troubleshooting Guide.
Layout method
95
TIP:
In case a particular substrate is often used for double-sided printing, to avoid having to redo the calibration between side A and side B, a second specific substrate could be used based on the initial one. Apply the advance and dynamic color registration of the side B: select this new substrate preset each time the side B is loaded (and select the previous one each time the side A is used).
Nesting
Nesting is a layout method that allows you to choose the layout of your printed jobs on the substrate, relative to one another, instead of simply printing them one after another as usual. Jobs can be printed side by side if there is room.
TIP:
Printing jobs side by side on the substrate gives you faster throughput and uses less substrate.
You can use nesting in the HP Internal Print Server, from the Choose Image File window or the Job
Properties window.
The Choose Image File window
From the HP Internal Print Server's main window, click the Add New Job icon to open the Choose
Image File window. You will see the Nesting check box on the bottom left of the window. If you select only one job, nesting is impossible and the box is grayed out. If you select more than one job, you can click the box to enable nesting.
NOTE:
To be nested together, jobs must be of the same resolution and printed on the same substrate.
Any incompatible job is added to the queue as a separate, non-nested job, and an explanatory message is displayed.
When you press the Open button with nesting enabled, the Advanced Nesting Arrangement window
opens (see The Advanced Nesting Arrangement window on page 97 ).
The Job Properties window
From the HP Internal Print Server's main window, right-click the print queue to open the Job Properties window. In this window, you can click the Add New Job icon to add more jobs, in which case you will see a Nesting section in the Layout pane.
96 Chapter 5 Printing options ENWW
Nested jobs must all be printed with the same number of passes. Therefore, the number of passes used for all jobs will be copied from the first job.
If you press the Arrange button in this section, the Advanced Nesting Arrangement window opens. If you use advanced nesting, the number of passes used for all jobs will be copied from the job with the highest number of passes specified.
The best location for the next added image is selected automatically.
The Advanced Nesting Arrangement window
The Advanced Nesting Arrangement window displays a preview of your jobs and their layout on the substrate.
●
You can alter the layout by selecting a job in the preview and changing the Left and Top values, or by dragging with the mouse.
●
You can zoom and scroll the preview.
●
You can rotate images at any stage.

Glossary
Aerosol filter
The printheads produce many fine droplets of ink, most of which are placed accurately on the substrate. However, a small proportion of these droplets escape sideways; the two aerosol filters are placed on either side of the printhead carriage to intercept them.
Bleeding
A print quality defect that occurs when the ink spreads on the substrate across areas of different colors.
Carriage beam
The beam supporting the printhead carriage as it moves back and forth across the printer.
Coalescence
A print quality defect that looks like a higher level of whiter grain.
Cockle
A substrate condition in which it is not lying perfectly flat, but rises and falls slightly in shallow waves.
Color accuracy
The ability to print colors that match the original image as closely as possible, bearing in mind that all devices have a limited color gamut and may not be physically capable of matching certain colors precisely.
Color consistency
The ability to print the same colors from a particular print job from print to print and from printer to printer.
Color model
A system of representing colors by numbers, such as RGB or CMYK.
Color space
A color model in which each color is represented by a specific set of numbers. Many different color spaces can use the same color model: for instance, monitors generally use the RGB color model, but they have different color spaces, because a particular set of RGB numbers results in different colors on different monitors.
Curing
Curing is needed to coalesce the latex, creating a polymeric film which acts as a protective layer, while at the same time removing the remaining co-solvents from the print. Curing is vital to ensure the durability of the printed images.
Drying
The heat applied in the printing zone removes water and fixes the image to the substrate.
ESD
ElectroStatic Discharge. Static electricity is common in daily life. It is the spark when touching the car door, or the cling of clothing. Although controlled static electricity has some useful applications, uncontrolled electrostatic discharges are one of the main hazards to the electronics products. Therefore, to prevent damage some precautions are needed when setting up the product, or handling ESD sensitive devices. This type of damage may reduce the life expectancy of the device or render it unusable. One way to minimize uncontrolled ESDs, and therefore reduce this type of damage is by touching any exposed grounded part of the product (mainly metal parts) before handling ESD sensitive devices (such as the printheads or ink cartridges). Additionally, to reduce the generation of electrostatic charge in your body try to avoid working in a carpeted area, and keep your body
106 Glossary ENWW
movements to a minimum when handling ESD sensitive devices. Also, avoid working in low humidity environments.
Ethernet
A popular computer networking technology for local area networks.
Firmware
Software that controls your printer's functionality and is stored semi-permanently in the printer (it can be updated).
Gamut
The range of colors and density values reproducible on an output device, such as a printer or monitor.
I/O
Input/Output: this term describes the passing of data between one device and another.
ICC
The International Color Consortium, a group of companies that have agreed on a common standard for color profiles.
Ink cartridge
A removable printer component that stores ink of a particular color and provides it to the printhead.
Ink density
The relative amount of ink that is deposited on the substrate per unit of area.
Ink deposit
The printheads sometimes expel a small amount of ink into the ink deposits in order to check the status of each nozzle.
Ink limits
A means of specifying the maximum amount of ink of all colors in total that can be laid down onto a given substrate.
Ink restrictions
A means of specifying the maximum amount of each color of ink that can be laid down onto a given substrate.
IP address
A unique identifier that identifies a particular node on a TCP/IP network. It consists of four integers separated by dots.
LED
Light-Emitting Diode: a semiconductor device that emits light when electrically stimulated.
Nozzle
One of many tiny holes in a printhead through which ink is deposited onto the substrate.
Passes
The number of passes specifies how many times the printheads will print over the same area of substrate.
Platen
The flat surface within the printer over which the substrate passes while it is being printed on.
Printhead
A removable printer component that takes ink of a particular color or colors from the corresponding ink cartridge(s) and deposits it on the substrate, through a cluster of nozzles.
Printhead cleaner roll
A roll of absorbent material used to clean surplus ink from the printheads after each pass over the substrate.
Spindle
A rod that supports a roll of substrate while it is being used for printing.
Substrate
ENWW
Glossary
107
A thin, flat material made to be printed on.
TCP/IP
Transmission Control Protocol/Internet Protocol: the communications protocols on which the Internet is based.
Tension
Tension is applied at the input and the output side of the printer. It needs to be evenly distributed along the whole width of the substrate, thus substrate loading is a critical operation.
Vacuum pressure
The vacuum applied to the substrate in the printing zone helps to hold the substrate down on the print platen, keeping the distance to the printheads constant.
