This is to inform about a problem that could occur in theory.
This problem, however, will not occur at an early stage but may develop as the machine is
used over a long period of time. This problem may only occur when the photoconductor
gap (PG) is at the narrowest setting (0.65 mm) and the doctor gap is at the widest setting
(0.70 mm). This PG/DG setting does not exist in production machines as far as checked in
the factory but is still within the adjusting range.
- Problem -
The lower seal (straight; the upper seal is a loop) of the development unit entrance seal
ass'y (P/N A2293092) may get pinched between the developer and the drum if a large
amount of developer accumulates near the photoconductor gap (PG). The seal may be
pulled out of position by the friction caused by the rotation of the drum. In the worst case,
the seal would peel off.
Upper seal
Lower seal
Drum
PG
Developer accumulation
DG
Upper development roller
- Cause -
The width of the lower seal is 18 mm, which may be too much. This problem does not
occur with the previous entrance seal ass'y (P/N A0963103) that has a width of 17mm.
- Countermeasure -
The width of the lower seal will be returned to the original 17 mm from 18 mm. Though the
17 mm lower seal may wrap up, the function of this part is not adversely affected. The part
number of the new development unit entra nce s eal ass'y will be A2293091.
This is to inform you about troubleshooting when black spots appear on the first copy after
warming up.
Problem
Black spots may appear on the front or rear side of the first copy after warming up. The
diameter of the spots is 3 mm at most. The number of spots may be around 20 in the worst
case.
Cause
When the machine turns off and the
temperature of the fusing unit becomes
low, toner adheres less strongly to the hot
roller cleaning roller [A] and pressure
roller cleaning roller [B]. In this condition,
the toner on the hot roller cleaning roller
[A], pressure roller cleaning roller [B] or
pressure roller cleaning brush [C] may be
transferred back to the hot roller or
pressure roller and may finally adhere to
the first copy after warming up.

This problem depends on how much
calcium carbonate comes out from the
copy paper and mixes with toner. When
more calcium carbonate is mixed with
toner, the problem becomes worse if the brush [C] is not installed.
According to tests, many brands of paper in Europe and Asia include a lot of calcium
carbonate and many of the American ones do not.
That is why the pressure roller cleaning brush [C] is installed only in the European and
Asian/Oceanian models to remove toner from the pressure roller cleaning roller [B]. (The
brush is not installed in the American model.)

Action
1. Please change the setting of SP1-103 from 0 (5.5 min) to 2 (15 min).
A longer fusing idling time can help to make the temperature of the pressure roller just
after warming up higher.
2. Please judge the necessity of the pressure roller cleaning brush by looking how the
mixture of toner and calcium carbonate adheres to the cleaning roller surface.
- Not necessary -
The brush is not necessary when the surface of the hot roller cleaning roller and
pressure roller cleaning roller looks shiny like the pictures below.

PAGE: 2/2

- Necessary -
The brush (A229 4153) is necessary when the surface of the hot roller cleaning roller
and pressure roller cleaning roller does not look smooth, with many small balls with the
mixture of toner and calcium carbonate like in the pictures below.
Hot roller cleaning rollerPressure roller cleaning roller
This is, however, just a recommended guideline and does not match all cases in the field.
Even in one machine, the condition of the cleaning roller surface may change in any of the
following operations.

With analog copiers, it has not been necessary to think about confidentiality of originals
used for copying. Our copiers have recently been shifting from analog to digital in many
segments. Since most digital copiers have a hard disk that can store scanned originals for
job completion (such as collating), we must prevent the scanned originals from being
recalled from the hard disk by someone else.
The following explains how the software handles the scanned images on the hard disk.
Please explain to the customers when required.
In the copy mode, when an original is scanned, the scanned original is stored as image
on the hard disk.
The stored image on the hard disk is deleted when the job is completed (when the Start
key turns green for the next job).

This is to explain an adjustment to minimize dirty background at the leading edge of the
copy due to overtoning in the development unit.
Symptom
Some toner is slightly visible at the leading edge of the copy.
Solution
Please follow the flow chart of the adjustment procedure on the following pages to
minimize the symptom.
Please note that since this adjustment is to stabilize the toner amount in the development
unit at a lower level to prevent overtoning, some customers may complain about a lighter
image in black solid areas, especially at an early stage from installation and for the first
several copies every morning.
Please adjust the SP modes for the development bias to meet the required level for each
customer.

However, there is no problem with text area.
New Factory Settings
To minimize the dirty background, the factory settings of some SP modes have been
changed to stabilize the toner amount in the development unit at a lower level which
prevents overtoning.
Please refer to the explanation on the following page for the details.
Because of the change of the factory settings of some SP modes, black solid areas may
be lighter at installation.
This model has a toner recycling system. The toner amount in the development unit is
determined with a calculation including not only new toner but also recycled toner. At
installation, the pipe for the recycled toner is empty and it takes 1,000 to 2,000 copies for
the first recycled toner to come into the development unit.
This means that the toner amount in the development unit is less during the first 1,000 to
2,000 copies after installation and becomes higher after that.
Please adjust the SP modes for the development bias to meet the required level for each
customer.

This bulletin will explain the recommended procedure for increasing the image density of
copies (in particular, the density of black solid areas on the left and right sides).
Symptom
1. The image density is low at installation.
2. The image density decreases during a continuous copy run.
3. Copies have lower image density on the left and right sides than in the middle.
There is no problem with text areas.

The symptoms described above are caused by a combination of the following:
1. As announced by RTB No. 9, the factory settings of some SP modes have been
changed to minimize the dirt y backgr ound.
These changes may affect the image density if originals with a high percentage of
black area and/or with black solid area at any of the sides are used.
2. The value of the toner supply ratio set in the SP mode is too low with respect to the
average percent of black area in the originals used.
3. The base toner control level in the development unit is set lower than the expected
image density level.
Action Required
Please adjust the toner supply ratio and the bias voltages for the ID sensor pattern and
for the image by following the adjustment procedure on the following pages.
Note
There might be some visible differences in half-tone areas and gray pattern areas
between the first copy and the other copies in a copy run.
This is because uncompressed data is used for the first copy and compressed data
stored in the hard disk is used for the other copies.

Symptom
The first page is blank and SC101 is displayed.
This symptom is limited to the first sheet after turning on the power. However, even on
the same machine, this problem does not occur every time the power is turned on.
Cause
The amount of light from the exposure lamp is insufficient.
If making a copy when the lamp is abnormally slow in reaching the ready status, the lamp
is not able to produce the required amount of light within the given regulated time period.
The source of the problem has been identified as defective internal components in lamps
that were produced in March 1999 (and is therefore limited to these lamps).
Action Required
The lamps produced in March were installed in machines produced in March, April and
May, 1999. If any machines have serial numbers matching those listed on the last page of
this RTB, please check the exposure lamp lot number by following the procedure
described below. If the lamps have lot numbers beginning with 39X, please replace them.
The number will be 39X, where 39 indicates a Ma rch 1999 production date and X in dicates
the actual day on which the lamp was produced. Each month is assigned a different lot
number (continuing from “37” in Jan. 1999). Therefore, January 1999 is “37”, February
=”38”, and March=”39”. This information can be found printed in black on the black lamp
cap at the rear side (and therefore may be difficult to read).
Procedure for checking the exposure lamp lot numbers (and replacement, if necessary):
1. Remove the exposure glass.
2. Slide the 1st scanner to the cutout in the rear scanner frame.
3. Read the lot number printed on the lamp cap.
4. If the first two digits of the lot number are 39, replace the exposure lamp.

2. Improvement for SC365 (Image Storage Address Error)
3. Improvement for Paper Jams in the Fusing Unit
4. Maximum Number Input for Paper Designate / Chapter Functions
SP5/SP5L
SC365 may sometimes be indicated when there is a timing error for passing image data into
memory during printing process.
The timing has been improved, so that the number of SC365 errors indicated unnecessarily
can be decreased.
If an accordion-shaped paper jam occurs in the fusing unit, none of the sensors in the machine
may detect it. If a customer does not notice the jammed paper at this time and closes the front
door without removing the paper, the machine enters the Ready condition again.
If the next job starts in this situation, the jammed paper in the fusing unit may wrap around the
fusing roller and the copies of the next job will not be completely fused.
To guide the customer to remove jammed paper which does not reach the Fusing Exit Sensor
as Index No. 107 of the Electrical Component Layout (or the Exit Unit Entrance Sensor as Jam
No. SP7504-15 on the Logging Data Sheet), the software has been modified, so that the jam
condition is not reset without pulling out and pushing in the fusing unit. This modification is
available only when DIP switch No. 4 on the I/O board is ON.
The maximum number which can be input for page numbers of the Designate / Chapter
papers has been changed from 99 to 250.

SP5/SP5L
When the files transmitted from PCs (600 dpi) and the scanned files (400 dpi) stored in the
Document Server are printed at the same time in duplex mode, a copy jam may occur or the
machine remains in copy mode without actual copying taking place.
When SP2506 functions during a copy job, the machine remains in copy mode without actual

Server
When files in the Document Server are printed in the Rotate Sort and Duplex modes on the

copies is not rotated.
This symptom occurs only when the Auto Tray Switching function of the System Settings in the
User Tools is set to “No”.
The “Finisher – Shift Tray” and “Finisher – Proof Tray” buttons in the User Tools (System
Settings – Basic Page 2 – Copy / Document Server / Printer: Output Tray) are displayed in the

7. Prepaid Card System
Please note that this modification has been made just to support the Prepaid Card
Systems presently working in the field, and there is no guarantee that all of the Prepaid
Card Systems can work with this software.
Symptom
A copy jam occurs when the credit on a prepaid card becomes zero.
How to Set
• Select “3. Prepaid Card” with SP5113.
• Select “Copy” in the User Tools. (System Settings – Count Manager – Set Key Card)
Note
The copy speed in the duplex mode is decreased by 40% because the interleaf feeding
method cannot be used.
The printing speed decrease in duplex mode can be bypassed by setting DIPSW No.1 on the
I/O board to ON, but some copies can be made without any credits on the card.
8. Key Operator Code
Modification
The valid area of the Key Operator Code can be extended by setting DIPSW No.5 on the I/O
board to ON, so that the Key Operator Code has to be entered when opening System
Settings, Copy Features, Printer Features and Document Server Setting in the User Tools.

1. Paper Jam in the Sub-unit in Connect Copy mode
When making copies in duplex, staple and connect copy modes, a paper jam may occur in the
sub-unit.
2. Black Image in the Trailing Edge Area of Copies from the By-pass Tray
The by-pass tray becomes empty during copying and if the size of the paper newly placed is
changed, a black image may appear at the trailing edge area of copies.
3. Request from the Italian Post Office
To meet a request from the Italian Post Office, the program related to the total counter has
been modified.

1. Paper Rotation by 180 Degrees
When a pre-printed paper such as letterhead paper is used as copy paper in the copy mode,
there is a case that the image on copies is rotated by 180 degrees against the letterhead. It
depends on whether the staple and/or punch modes are selected. So, customers need to be
careful in which way pre-printed paper types are loaded for each copy job.
Improvement
By turning on DIP switch No. 8 on the I/O board, the image is always rotated by 180 degrees.
So, customers can load such paper always in one way.
Note
This improvement is not valid for by-pass feed.
2. SC302-1
Symptom
SC302-1 may be displayed during the process control initialization.
Cause
It is not a real problem but the conditions to detect the SC are too strict.
Solution
The conditions have been changed not to detect SC302-1 mistakenly.

3. SC302, SC391 and SC401
4. SC990 when Initial Mode in User Tools is Set to “Program No. 10”
5. Drum Reverse Rotation
SP5/SP5L
Symptom
When SC302 is detected, SC391 and SC401 usually follow.
Cause
These SC’s are all related to high voltages. When one of them is detected, the supply of all
high voltages is immediately stopped. So, not only the original SC number is displayed but
also the others follow.
Solution
Only the original SC number is detected.
Symptom
SC990 may be displayed when the Modes Clear key is pressed.
This symptom only occurs when the Initial Mode in the Copy Features of the User Tools is set
to “Program No. 10” and two machines are connected in tandem.
Solution
The software bug is corrected.
The condition of the drum reverse rotation has been changed to minimize load of the related
parts. (See service manual Page 2-58)
Old
At the end of every copy job.
New
Only when the following two conditions are fulfilled:
• When a copy job is finished.
• When the total time of drum rotation has reached four minutes since the last rotation.

6. Charge Corona Cleaner Movement
The condition for detecting an error in the charge corona cleaner movement has been
changed not to count a SC up too early even when the movement is not so smooth.

Retrofit information
This bulletin will explain the recommended adjustment procedure for when the image
density on the whole page becomes lighter and lighter day by day because of low monthly
copy volume.
This bulletin is different from RTB #15, which is for lower image density in solid black
areas.
SYMPTOM
The image density on the whole page of the copies becomes slightly lighter and lighter day
by day.
POSSIBLE CAUSE
The monthly copy volume is very low.
When the co py volume is low, the mixing time in the development unit is shor t. This
causes the chargeability of the tone r to become lower. In this condition, the TD sensor
tends to detect that the toner amount in the development unit is more than the actual
amount, so not enough new toner is supplied.
During the process control initialization the next morning, Vcont is determined at a lower
value than the previous day because of the reduced toner amount in the development unit.
ADJUSTMENT PROCEDURE
Before starting the adjustment, do the following:
• Calculate the average monthly copy volume.
• Check the value of SP2906 (Vcont Manual Setting).
• Check the setting of SP2967 (Auto Image Density Adjustment)
• Print out the SMC sheets (SP5990-1)
• Make several copies as samples and check the image density.

SYMPTOM
The toner recycling pump locks.
CAUSE
The quality of recycled toner gradually decreases, eventually hardening and clumping to
the point where the Toner Recycling Pump is no longer able to effectively circulate it.
Note: In particular, this occurs when the surrounding temperature of the machine is high,
such as in relatively high-temperature environments or when there is a minimum amount
of free space around the machine.
SOLUTION
Replace the Pulley and Timing Belt with the modified parts listed below, which will
effectively increase the drive power of the pump from 225 rpm to 400 rpm.
