5.4.1 Adjusting the capping position

This procedure is used for aligning the capping position correctly by adjusting the capping position parameters in the firmware. When this item is selected, the printer carries out the home position detection sequence and then automatically pushes the carriage against the maintenance unit to detect the carriage position at that time. The position displayed is the distance from the home position flag.

Press [ENTER] to update the capping positions and move to “AJST: Measure High”, press [Back] to move to

“AJST: Home” without updating the capping position.

120 AP-74038, Rev. 1.1, 25/01/05


5.4.2 Check Media Skew

This procedure will feed a specific amount of paper (a single pass band feed) and the sensors will read the position of the edge of the media before and after feeding and check for any discrepancy. If no media is loaded when this item is selected, you will be asked to load the media. After media initialization, when the amount of media feed is entered, the edge sensors will detect the left and right edges of the media and media feed will begin. After feeding the specified amount, the edge sensors will again detect the left and right edges of the media and any difference from the readings before media was fed will be checked and displayed. A media recognition error before and after feeding, or detection by the rear sensor of no paper during feeding, will cause a media error to be displayed and this procedure may be terminated by pressing any key. To terminate the procedure when processing is not in progress, press [Back] on the panel or [ESC] on the terminal.

Caution:

Make sure media is properly loaded.

The first time this adjustment is made, the reference position for media skew will be determined by detecting the right edge (origin side). If the adjustment is made with a bad media loading position, that position will become the reference position and “Media skew error” will occur frequently.

Press [ENTER] to move to “Adjustment: Rank Input” or [Back] to move to “AJST: ChkPaperMov”. Other panel keys are ignored during processing.

122 AP-74038, Rev. 1.1, 25/01/05


5.4.4 How to Check Head Nozzles

After filling the inks, this procedure uses printing results to check whether the head nozzles are ejecting the ink properly. If the nozzles are ejecting ink badly, implement the cleaning treatment in this procedure. If there is no media, the printer will request media. If it is out of ink, it will ask for an ink cartridge. If there is media and ink, the Head Nozzle Check Pattern will be plotted.

Note:

If there are cartridges but the ink has not been filled, the printer will still start printing.

This and subsequent items that require printing for adjustment or checking include requests for media and inks. If the [CANCEL] key is pressed during printing, the printer will stop printing.

5.4.12 How to Adjust the Rear Sensor Position

This procedure is used to ensure the proper detection of the length of cut sheet media. It adjusts the position of the rear sensor in the firmware by entering the media length after cut media has been loaded and detected. This item is essential in the production process but it is no longer necessary once media feed distance compensation has been carried out. When this item is selected, whether media is loaded or not, it will ask for cut sheet media. If panel diagnosis decides that media is loaded, this will be assumed to be cut sheet media and media initialization will begin. Therefore roll media should not be loaded. After the media has been initialized, it will be ejected. To terminate this program without updating the setting, press the

[Back] or [ESC] key while no processing is in progress.

163 AP-74038, Rev. 1.1, 25/01/05


7.2.7 Y Rail Fitting Precision measurement

Caution:

The Y Rail fitting precision affects picture quality and rectangular accuracy. If, for any reason, you think the precision has altered or the frame and XY rails have been removed and readjustment is necessary, special jigs are available for taking measurements. If the Y Rail height has changed, this will affect picture quality precision and capping precision. If the amount of change is minimal, it can be recovered by picture quality adjustment and zone delay compensation but if it exceeds a certain amount (maximum value - minimum value ≥ 0. *), it will be beyond the range of control by zone delay.

If Y Rail parallelism (L2) has altered, this will affect rectangular precision, XF sensor and cutter head distance, capping precision, etc.

Y Rail height measurement can be measured with the covers fitted but the jig must be fitted in a place where there is no pressure unit. Fit the Jig Assembly to the Y

Rail and read the measurements with slight pressure. For Y Rail parallel precision, the position of the Frame and Y Rail is controlled by the gauge jig. The gauge jig is used with the Steel Belt, Y Pulley Box and Y Return Pulley removed.

7.2.7.1 How to use the special jig

Step 1 : Set up by pressing the Rail Height Jig Assembly into the Y Rail Height Reference Base Assembly and set the dial gauge to “0”.

Step 2 : Mount the rail height gauge over the rib and adjust the platen up and down until the dial gauge reads 2.6 to 2.7 mm. Refer to “Adjusting the Platen Height”

(2.6 to 2.7 is the absolute height dimension L1)

164 AP-74038, Rev. 1.1, 25/01/05


7.2.7.2 How to control precision and specifications value

Step 1 : In fitting the Y Rail, the height is fixed by pressing on frame guide pins (left and right in each of two places) and parallelism is fixed by the inserting the Y Rail fitting control jig (JD-42051) between the Y Rail and the Frame. At this time, it doesn’t matter whether you use the capping side as the reference and the opposite side becomes the contact point (where there are guide pins).

165 AP-74038, Rev. 1.1, 25/01/05


7.2.8 Head Cleaning Procedure 1

Caution:

When to Clean the Head

“Head Cleaning” must be carried out whenever this printer is moved by truck (refer to

“Transporting the printer”) or when the parts shown below are replaced. (Refer to “Head

Cleaning Procedure”) When this operation is performed, there is a risk that the inks remaining in the head and ink tubes may be spilt and soil the printer.

< Replacement Parts > Head, Damper, Head Cable, Cartridge Frame Assembly, Ink

Tubes.

Head Cleaning Jig

When you are using the Head Cleaning Jig, the 100 cc jig bottle should contain at least

50 cc of cleaning fluid and its cap should be loosened. If the cap of the jig bottle is tightly closed, the ink will flow back into the bottle. Also, when you have finished using the

Head Cleaning Jig, return the cleaning fluid from the 100 cc bottle to the 500 cc cleaning fluid bottle.

What to do After the Initial Filling

Wait for at least 30 minutes after the initial filling before you use the printer for printing.

Otherwise picture quality can not be assured.

Head Cleaning is a self-diagnostic function not available to the user.

The following two methods can be used. Refer to BAC2150 for details. o

“Panel Diagnosis” implemented from the panel only, and o

“Personal Computer Diagnosis” implemented by connecting a personal computer.

Black and color head cleaning may be done separately or all four colors may be done together.

Panel Diagnostic Functions (when implemented from the panel only)

Step 1 : To run panel diagnostics, turn on the power while holding down the [Cleaning], [Menu] and [Shift] keys on the panel.

Step 2 : Select self diagnostic “Adjustment” and “Home”.

Step 3 : Select Black, Color or Both and press the “Confirm” key.

(In the case of Both, the Head Cleaning sequence will be Black followed by Color.

8.2 DAILY MAINTENANCE

This chapter describes routine maintenance such as cleaning, exchanging ink cassettes, etc.; and offers solutions for minor problems that may occur during printer operation.

8.2.1 How to clean the printer unit

Rockhopper 38 printer should be wiped free of dirt with a dry soft cloth.

Caution :

The power switch of the RJ-4000 series printer should be switched off during cleaning.

Don’t use solvents such as thinners or benzene that will damage the finish.

Covers that are fixed with screws contain electrical components and must not be opened during cleaning.

Paper dust which is produced when the printer is working should be removed periodically. Make sure that it does not get blown around.

Stubborn dirt that is difficult to remove may be removed with a lint-free cloth dampened with alcohol.

Use a soft damp cloth to wipe away any paper dust adhering to the printing board and cutting groove.

Important:

Paper dust will accumulate with long term use and stick to the plotting board and cutter groove and may cause printing quality and cutting performance to deteriorate.

They must be cleaned periodically.

Use a soft damp cloth to wipe away any paper dust sticking to the pressure roller. Clean the grid roller with a nylon brush.

177 AP-74038, Rev. 1.1, 25/01/05


Important:

Paper dust sticking to the pressure roller and movable roller may prevent normal feeding of the media and produce a “Skew check error”. They must be cleaned periodically.

Use a cotton bud to wipe away any dust and paper dust from the front and back paper sensor covers in two places.

Important:

Progressive soiling will affect the sensitivity of the sensor and faulty detection of the media in the initial operation may cause a “Skew Check Error”. They must be cleaned periodically.

178 AP-74038, Rev. 1.1, 25/01/05


8.2.2 Replacing the ink Cassettes

When a Rockhopper 38 series Printer displays “No ink” or “No Cartridge”, the cartridge should be replaced or filled without delay. Also, ink cartridges should be prepared when “[YCMK] Ink Near End” is displayed.

To replace the ink cartridge, please follow the procedure mentioned below:

Step 1 :

If “No Ink” appears on the display, when there is no printing operation in progress, pull out the ink cartridge whose color is indicated from the back of the printer.

[YMCK] cartridge

Note:

Each sign [Y] [M] [C] [K] indicates:

Y : Yellow, M : Magenta, C : Cyan, K : Black.

Colors for “No ink” are expressed as colors from 1 to 4

Step 2 : Unpack a new ink cartridge packet.

Note:

Only use original Mutoh ink cassettes.

For each cassette, there is a correct place and a correct inserting direction.

Open the ink cassette just before inserting it into the slot.

Use ink cassettes within two years from the date printed on the package.

Replace your ink cassettes at least every 6 months.

Step 3 : Insert a new ink cassette into the slot.

Step 4 : When insertion / replacement of ink cassettes has been performed well, the display will show the following message if media is loaded and the printer is ONLINE: “PLOT OK”

179 AP-74038, Rev. 1.1, 25/01/05


8.2.3 Replacing the cutting blade

Depending on the kind of roll media used, paper dust gathers in the cutter slot and on the cutter blade edge.

This may cause bad sheet off quality. In this case, replace or clean the cutting blade or/and clean the cutter slot.

The cutting blade is a consumable item so if the blade loses sharpness, replace it.

We recommend replacing the cutting blade regularly.

Step 1 : Switch off the printer and pull the printing head to the center of the printer.

Step 2 : Take out the cutting blade by pushing the cutter head down and rotating the cutter arm towards you. Either clean the cutting blade with a dry cloth or replace it.

Caution:

There is a spring fitted in the hole of the cutter head. Be careful not to loose it while replacing the cutting blade.

Step 3 : Insert a new cutting blade in the hole of the cutter head. While pushing the cutting blade down, put the cutter arm back over the cutting blade. A cutting blade can only be inserted in one direction.

Caution:

The edge of the cutting blade is very fragile, while replacing it, handle it with care.

180 AP-74038, Rev. 1.1, 25/01/05


Step 4 : Put the head manually back into its capping position, and turn the power switch ON.

Note:

Durability of the cutting blade may differ depending on the kind or thickness of the media and used environment. We recommend purchasing a spare cutting blade so that you always have a spare blade at hand.

Important:

If you don’t have a new sheet-off blade available to replace your blade, you can temporarily switch off the automatic sheet-off. o

8.2.4 Emptying the waste bottle

When printing A0 size or larger widths, very small amounts of ink will be ejected on the left edge for stable printing quality. The waste ink ejected on the left side in that way is collected in a translucent bottle under the main unit (the waste ink bottle).

Step 1 : Since there is no panel display or lamp display when the waste liquid absorbent sheet in the waste ink bottle is to be replaced, you should prepare to replace the waste liquid absorbent sheet when you see that the bottle is about half full. Have a new absorbent sheet, a thick vinyl bag and a pair of forceps ready.

Note:

Conditions vary for the waste ink bottle to become half full but it will be after printing about 2000 A0 pages.

Step 2 : Remove the waste ink bottle by turning it to the left. Using absorbent sheet and forceps, soak up the waste liquid in the bottle and discard the waste liquid absorbent sheet into the open vinyl bag.

Step 3 : The waste ink bottle, fitted with new waste liquid absorbent sheet, is installed in the printer by turning it to the right.

Caution:

The used waste liquid absorbent sheet should be disposed of as non-combustible material in accordance with your local civic regulations.

It would dangerous for children to lick or swallow the absorbent sheet filled with waste liquid, so dispose of it promptly or put it out of reach.

If you accidentally touch the waste liquid, wash with soap and water at once.

If it should enter your eye, wash with plenty of water and see a doctor. If it is licked, gargle with water and wash out straight away. If it is swallowed, immediately drink plenty of water and consult a doctor without delay.

182 AP-74038, Rev. 1.1, 25/01/05


8.2.5. Replacing the blades

Please follow the procedure below to install the new blades, which has to be done every year as part of the periodical services done by an authorised Mutoh technician.

Step 1 : Put the lever up.

Step 2 : Remove all the blades as shown in the picture below.

Remove previous blade (wing) Two pins on each side of the pressure roller

Step 3 : Install the new blades. Make sure that the 4 pins of the pressure roller match with the holes in the blade.
