2. PRECAUTION FOR MAINTENANCE AND INSPECTION
・ Before starting maintenance and inspection work, be sure to turn the power off and remove the power cord from the outlet.
・ Photo sensors are used in various parts of this machine. Be sure to clean them when maintenance work is conducted.
・ Thin wires are used for wiring in circuit boards. Be sure to grip the socket when setting or removing the connector.
Also, when setting the connector, take care that wires are not stretched too tight and slack wires are not in contact with the drive units and insert the socket into the end. Should the wires are in contact with the drive units, it may cause a disconnection.
3. SETTING PAPER
(1) Use the fill line on the paper guide as the loading capacity. In case of printed paper, do not load too much as it tends to swell.
(2) Fan out sheets well and then load them on the feed table. Failure to properly fan sheets may lead to trouble.
[How to fan out sheets]
1) Pinch the sheets of paper at both ends.
2) Bend them to admit air.
(Loosen the force lightly and pinch them again after bending)
3) Jog and align the sheets vertically.
(3) Align sheets at the edges and insert them until they lightly strike the forward guide. Failure to properly align sheets may lead to double feed or no feed.
(4) Make sure any ink on the paper is dry. Let ink dry before loading paper. Wet ink soils the feed rollers and the separator rubbers. It can lead to malfunction, such as double feed or no feed.
(5) Copied sheets may cause wrong feed or stacking error owing to electrostatic charge. Static electricity can be controlled by spraying a retail static eliminator on the feed rollers and the front edge of the paper.
Too, since copied sheets are apt to curl at the edges; straighten or invert them before feed table loading.
(6) Be sure to load no-carbon-required paper (general quality) with the color developing side (usually the print side) down, otherwise the side coated with color former will probably be marked with rubbed traces when contacting the feed roller.
(7) Front and back sides of ejected paper change according to ejected direction (with independent use or when connected). Be very careful when the collator is operated with after-processing equipment such as the booklet maker.

3.2 Order of loading paper
(1) Paper with the printed side down
Load the paper on the feed tables from bottom to top in ascending order of pages.
In this case Page 1 appears at the top of collated sheets on the stacking table.
(2) Paper with the printed side up
Load the paper on the feed tables from top to bottom in ascending order of pages. Paper is fed to the stacking table turned over.
In this case Page 1 is at the bottom of collated sheets on the stacking table.
Note
How to load a paper with a small number of pages (using less than 10 stations)
・ In case the collator is used independently or a staple is connected with it, load the paper in order from the bottom (10th station).
This way prevents disorder in paper ejection and facilitates the processing speed.
・ In case optional machines are connected with the collator (such as two towers of the collator are connected with a large-capacity stacker or a booklet maker.), load the paper in order from the top (1st station).
This way prevents paper jam.
Alternate
・ Loading paper with the printed side up in Alternate mode
Load same pages on odd and even-numbered stations, that is, Stations 1 and 2, 3 and 4, 5 and 6, 7 and 8, 9 and 10.
Paper feed starts with the odd-numbered station; if it runs out of paper, the neighboring even-numbered station will automatically start feeding.
8
・ Loading paper with the printed side down in Alternate mode
3.4 Loading paper in Insert and Program mode
(1) Insert mode
Load partitioning paper on the top station to be used. For instance, if 10 stations are used continuously top to bottom, partitioning paper should be loaded on Station 1.
(2) Program mode
Be sure to load paper with the printed side up.
For example, when 10 stations to be used continuously top to bottom, front covers should be loaded on Station 1, back covers on Station 10.
If fewer than 10 stations are used, load front covers on the top station, back covers on the lowest of those to be used.

・ Replacement of paper feed rubber rollers
Remove the paper feed tables. While holding the paper feed shaft, push it into the left, then pull it toward you. If the paper feed rollers are dislocated, correct their positions; the center rubber roller should be located at the center of the separator.
Caution!
When the paper feed rubber rollers are replaced, mount them on the paper feed rollers holders so that the white dot of the rubber rollers is on the right-hand side. In addition, after mounting the paper feed rollers on their holders, roll them on a flat surface such as a desktop to make sure they are mounted horizontally. If mounted askew, problems like paper feed failure or double feed may occur.
・ Replacement of separators
After removing the paper feed shaft, remove only the rubber portion of the separator by stripping it off with a flat head screwdriver or the like.

11.2 Adjustment of the paper feed photo luminescence intensity
Adjustment will be required if the followings occur when the CHECK key is pressed to feed paper.
(A) The station lamp flashes red (due to excess or lack of luminescence intensity)
(B) The EMPTY FEED lamp lights though the paper is fed.
In case of (A),
Remove the error display and press the CHECK key again. Then, the collator will automatically adjust the luminescence intensity. This check operation may be repeated several times according to the luminescence intensity and the type of paper to be used.
In case the red lamp flashes every time, it is recommended to reset the luminescence intensity. In such case, the following procedures should be taken.
1) Repeat checking procedures until error does not occur (luminescence intensity)
2) Press 0 key for three seconds to set the system constants setting mode. ([P x] will be displayed)
3) Press the START key to memorize the amended value of luminescence intensity.
In case of (B),
In case luminescence intensity is too strong against the paper thickness, it may occur that the light penetrates the paper, resulting in empty feed error. In this case, luminescence intensity must be reduced manually. The following procedures should be taken.
1) Press [0] key for three seconds to set the system constants setting mode ( [P x] will be displayed)
2) Lower the value of luminescence intensity on display.
Press the [4] key to increase the value by one.
Press the [0] key to reduce the value by one.
*1: The appropriate value of luminescence intensity is 3 to 4 (in case 64kg/m 2 paper is used). Use this value for standard. Take care as the value varies according to the sensitivity of paper feed photo, quality of paper used, and printing condition.
*2: The value of luminescence intensity indicated herein is that for Station 1. The right value for
Station 1 may not always be appropriate for other stations. If the value of P is altered, the same value will be set at all other stations.
3) Press the START key to memorize the amended value of luminescence intensity.
Press the CHECK key for temporary setting (The set value will return to the initial value when the power supply is cut off).
Press the START key to memorize the set value (The altered value will be stored even if the power supply is cut off.
22
11.3 Releasing double feed detecting function
In case double feed cannot be detected since paper used is too thick (Err3), collation can be continued by canceling double feed detection function.
(1) Press [0] key for three seconds ( [ P x ] will be displayed).
(2) Press the [MODE] key to display [A xxx] ( xxx represents the current set value).
(3) Press the [1] key to display “0” in the third digital figure.
(4) Press the CHECK key or START key to reflect the change.
Press the CHECK key for temporary setting
(The set value will return to the initial value when the power supply is cut off).
Press the START key to memorize the set value
(The altered value will be stored even if the power supply is cut off).
11.4 Initializing the system constant (return to factory-set value)
In case the machine work becomes unstable after the system constants are altered for adjustment, the system constant can be returned to the factory-set values.
(1) Turn off the power of the collator.
(2) While pressing the CLEAR key, turn on the power.
Caution!
With this initializing procedures, all set values including those for Insert and Chit modes are deleted and returned to the factory-set values.
Necessary data should be jotted down before deletion and used for re-setting.

Explanation of System Constant Setting by Symptom and Purpose
1. The station lamp blinks in red at check (System constant P)
Double feed detection cannot be performed at check. Accordingly, the lamp blinks in red at check when the sensitivity of the paper feed photo sensor does not match the applied paper.
The red lamp blinking condition is classified into 2 cases by paper quality and sensor sensitivity.
1. The sensor sensitivity is weak for paper thickness
In this case, the station lamp blinks more slowly than blinking counter [Err].
(1) Clear the error and make a check again. With this, the collator adjusts the sensitivity automatically.
(2) Set the system constant P value to a stronger value so that this value may be proper.
The above 2 countermeasures are available.
2. The sensor sensitivity is stronger for paper thickness.
In this case, the station lamp repeats 3-time blinking. (This is slightly faster than blinking counter
[Err].)
(1) Clear the error and make a check again. With this, the collator adjusts the sensitivity automatically.
(2) Set the system constant P value to a weaker value so that this value may be proper.
The above 2 countermeasures are available.
When the sensor sensitivity is too strong for paper thickness, the presence of paper may not be detected. In this case, the only countermeasure to be taken is to manually set the system constant P value to a weak value.
The system constant P adjusts the sensor sensitivity by operating the output of the luminous side of the paper feed photo sensor. For the system constant P, 15 different values can be set as below.
1 , 2 . 3 , 4 , 5 , 6 , 7 , 8 , 9 , A , b , c , d , E , F

2. Canceling double feed detection (System constant A)
There is a rare possibility that the sensitivity of the paper feed photo sensor may not be fitted to paper by adjusting the paper feed photo sensor with the system constant P. At this time, cancel double feed detection to attain a paper feed as a temporary measure.
Double feed detection can be canceled by setting the system constant A.

3. Changing the paper feed wait time at connection of an option (System constant L)
When a post-process machine such as a booklet maker is connected, the paper feed cycle of collator may be made shorter or longer in some cases. In these cases, the time from the passage of paper through the paper feed photo sensor at the end till the execution of the next paper feed (*1) at collator side can be adjusted in the range of 0 to 60 seconds by operating the system constant L.
*1: In case of paper ejection to the booklet maker (in case of connection with KAS or Plockmatic booklet maker) without control, the electric signal is not communicated between the collator and the booklet maker. Therefore, the paper feed waiting time (L value) is directly reflected. On the other hand, in case of paper ejection to the booklet maker with electric signal Communication (in case of Foldnak booklet maker), the time after a paper eject response signal output from Foldnak until the next paper feeding starts is set as the paper feed waiting time (L value).

4. A left error occurs though a normal process has been performed when using a large-capacity stacker or Foldnak. (System constant n)
In a machine such as a large-capacity stacker and Foldnak that returns a paper ejection response to the collator, a left (option device) error may be caused to the collator though the paper process has been normally performed.

Note:
When the system constant L to adjust the paper feed interval is set to a large value, the wait time for the next paper feed (system constant L) may exceed the paper ejection response wait time (system constant n). In such a case, a left error will occur though the paper process has been normally performed. Set the system constant n value to “System constant L + 1.0” or more.
The system constant n varies depending on the connected device.
• Basic value: [n 5.0].
• When a stapler-puncher or large-capacity stacker is connected: [n 3.0]
5. Changing the paper interval between stations at connection with after processing machine
(System constant G)
When the booklet maker is connected, the interval of paper feed timing with the next station can be changed.
In some case, it may be necessary to determine which should first come out, the paper from the top station or the paper from the bottom station. In this case, it may be attained by operating the system constant G.
1 Aligning the paper ends
When the system constant G is set to 180 for the 60 Hz regions, paper will come out with the paper ends almost aligned.

3. Causing the lower-station paper to first come out (*)
When the system constant G is set to a smaller value than 180, the lower-station paper will first come out. For such an after processing machine in which paper alignment is performed by paper jumping as a large-capacity stacker or a jogger, use this setting.

Note: How much does the ejected sheet-to-sheet distance shift if the system constant G is incremented or decremented by 1?
The space of the paper feed table of the collator is a distance of 3.1
" for each station. Aligning paper ends delays a paper feed by 3.1
" each for each station.
From calculation with the G value (160/180) at a paper feed with the paper ends aligned, the following shift amount is caused by incrementing or decrementing the system constant G by 1.
For the 60 Hz region: 3.1
" 180 = 0.02
"
28
However, the ejected sheet-to-sheet distance varies greatly depending on the paper feed condition.
• Wear of the paper feed roller/separator
•
•
Feed paper slip amount
Feed paper collapse amount
Due to the above factors, the ejected sheet-to-sheet distance may be different from what is calculated. Make an adjustment referring to this numeric value.
6. Adjusting the paper feed timing between the left and right towers at 2-tower connection (System constant S)
When 2 collators are connected, it may be necessary to adjust the paper feed timing of the right tower and the left tower. After adjusting the ejected sheet-to-sheet distance of each station of each tower (refer to the system constant G), adjust the system constant S. With this, the paper feed timing can be adjusted between the left and right towers. Operating only by the left tower is enabled.
1. Align the paper heads of a collated set from each tower
Set the system constant S value to 170 to align the paper heads from the left and right towers.
2. Causing the paper of the left tower to first come out
Set the system constant S value to a small value to cause the paper of the left tower to come out earlier than the right tower.
3. Causing the paper of the left tower to later come out
Set the system constant S value to a large value to cause the paper of the left tower to come out later than the right tower.

Note: How much does the feed timing of one collated set from the left tower shift if the system constant S is shifted by 1?
A ten-fold value of the reference value of the system constant G is used for the system constant S value. Accordingly, when the numeric value is shifted by 1, the following shift is caused.
For the 60 Hz region: 0.02
Regarding this value, an error will be caused depending on the paper feed condition like the system constant G.

Due to the above factors, the shift amount may be different from what is calculated. Make an adjustment referring to this numeric value.
7. Ejecting paper to the left side without an external connector (System constant J)
If the paper ejection side is switched over to the left side in the status where a connecting cable for the post-process machine is not connected, the collator does not eject paper. The above specification is intended to prevent a misoperation. However, operating the system constant J permits ejecting paper to the left side without an external connector.
