Correction of finisher malfunctions that occurred when the printer controller was installed
and used with a test machine:
• Door Open is indicated after staple job.
• After a staple job, the Staple Unit does not move to the staple supplying position in the
staple end condition.
• Stapled sheets of paper fed out incorrectly when the interrupt function is used during
printing.

Solution for a symptom that occurred when emptying the finisher copy tray :
Bellini
Date:
30-May-00
No.:
RA294014
Symptom
In a large copy job, the machine stops with 3000 sheets on the finisher tray. As the
operator removes the copies, the machine restarts immediately and the tray is still in the
down position. This causes the copies to fly out of the trays. The tray moves upwards to
the correct position if the Stop button is pushed.
Cause
Once the finisher detects that the tray is in the bottom position, it takes 1.5 seconds for the
finisher to send the signal to the mainframe to stop the copy job.
Solution
Software change: The finisher sends the stop signal to the mainframe at the same time it
detects that the tray is in the bottom position.

For your reference:
This is the solution for the following problem that was reported:
When the paper stack is removed when the tray is full, the stack height sensor feeler
drops. Then, 1.5 seconds later, the finisher raises the tray and the sends the "wait" signal
to the copier. The copier then immediately stops the paper flow exiting to the finisher.
When the tray is lifted to the top position, the finisher sends the "wait clear" signal to the
copier. Then, the copier restarts exiting the paper to the finisher.
If the copier does not receive the "wait" signal, it restarts exiting the paper immediately.
The following condition has also been reported.
When lower limit sensor 2 is activated while the paper is exiting to the finisher, the finisher
sends the "lower limit" signal to the copier. The finisher stops lowering the tray. At the
same time, the copier stops the paper from exiting. Here, copying is stopped by the tray
full condition, not by the "wait" signal. When the stack of paper is removed, the paper load
is lifted and the tray lifts up slightly because it is suddenly lighter. The lower limit sensor 2
may deactivate at this point. In this case, the finisher will not send the "wait" signal to the
copier. Therefore, the copier will restart exiting the paper to the finisher. If the paper
passes the stack height sensor within 1.5 seconds, the tray cannot be lifted. This caused
the copies to fly out of the trays.

The punch waste is collected in the punch waste hopper [A], which is under the punch unit.
Incorrect
When the punch waste covers the hole [B] in the hopper, the punch waste hopper sensor
[C] turns on and a message will be displayed after the copy job finishes.
Correct
When the punch waste covers the hole [B] in the hopper, the punch waste hopper sensor
[C] turns on and a message will be displayed in the operation panel LCD. Then, the copy
job will be stopped. After emptying the punch waste and returning the punch waste hopper
[A] to the finisher, the copy job will be resumed.

SYMPTOM
When stapling more than 50-70 documents with front and rear cover sheets, the front
cover is not squared up before stapling. The alignment is within standard (2 to 30 sheets
stapled: 2 mm, 31 to 100 sheets stapled: 3 mm). However, some customers request a
better alignment.
CAUSE
1. The exact position where the jogger stops differs for each paper type. It is necessary to
adjust the staple jogger position for each type.
2. The trailing edge of paper with a large curl may not be aligned with the stack stopper in
the jogger unit.
SOLUTION
Solution 1 (Staple Jogger Span Adjustment)
SP6120 adjustment becomes effective when the finisher firmware is updated to version C
or later and the mainframe firmware is updated to version 7.23.2 (F) or later. If the
mainframe firmware is updated without the finisher firmware, SP6120 will be displayed in
SP Mode but will not be effective.
The staple jogger positions for each paper size can be adjusted with SP6-120 as shown.

Note: In addition to installing the new three fences, it is necessary to attach two Mylar
Guides (B3024517, Index 6) to the Front and Middle Positioning Fences.
1. Remove the two springs (index 2) hooked on the Slide Holder Shaft Bracket (B3024742:
Index 9).
2. Remove the securing screws for the front and rear shafts (B3024541: Front Shaft - Slide
Holder, Index 10 & B3014542: Rear Shaft - Slide Holder, Index 21).
3. Slide out the front and rear shafts from the Staple Unit Lower Stay (B3024741: Index
11).
4. Remove the old positioning fences (Index 4, 5, and 8).
5. Attach the two Mylar Guides (B3024517: Index 6) to the Front and Middle Positioning
Fences as shown in the illustration on the next page.
6. Install the new positioning fences (front, middle, and rear).
7. Return all removed parts.
Note: Make sure that the two springs are put back correctly.

SYMPTOM
SC729 is displayed, or the mainframe does not detect the finisher.
CAUSE
1. Electrical noise generated by the drive motor affects the initial check routine of the
punch drive board firmware, so that the motor reset signal is constantly sent out. The
only units on which the symptom may occur are the USA two-punch-hole and European
fourpunch-hole units.
2. The two screws securing the heat resistor to the IC on the punch drive board come
loose. As a result, the temperature of the IC becomes too high.
SOLUTION
1. The software has been changed so that the drive motor reset signal is deactivated at the
proper time, even if electrical noise occurs.
Production units:
The ROM on the finisher main board has been changed from the beginning of
September 2000 mass-production, and on some units from August mass-production.
Old ROM P/N: B302-5103F
New ROM P/N: B302-5103G
Listed below are the serial numbers for August production finishers that contain the new
modified ROM.
