While SP2-207-2 (Toner Bank Toner Supply) is performed at installation, the rotation of
the toner hopper gear (AB013748: Joint Gear -15Z) may cause an oversupply of toner
from the hopper to the development unit. This in turn causes relatively high image density
in copies/printouts made just following installation. To correct this, machines in mass­production have been modi fied as fol lows:

Temporary Solution

The toner hopper contains a red idler gear (A2943255: Idler Gear - 15Z). This gear
reduces the drive supplied to the toner hopper and prevents the oversupply of toner that
occurs in the initial period following installation .

The toner hopper gear for normal operation (White gear:AB013748: Joint Gear -15Z) and
a spare C-ring (07200060B: Retaining Ring - M6) have been packed in the accessory
plastic bag.

The procedure for the Toner Hopper Drive Gear Replacement (Joint Gear - 15Z) has been
packed in the accessory plastic bag. The procedure is also included on page 2/3 of this
bulletin.

Action required

Replace the red idler gear with the white gear after carrying out SP2-207-2 (Toner Bank
Toner Supply) by referring to the procedure for the Toner Hopper Drive Gear Replacement
(Joint Gear - 15Z) packed in the accessory plastic bag. The red idler gear is not
necessary after machine installation.

Permanent Solution

The permanent solution is basically the same as the temporary solution. To facilitate gear
replacement, the gear has been mounted with screw (09513006B: Philips Screw With Flat
Washer - M3x6) instead of a C-ring. The procedure is included on page 3/3 of this bulletin.
Regarding the cut-in serial numbers for this modification, we will issue an MB as soon as
they are available.

The part number of the toner hopper unit will be changed from #A2943200 to a new part
number due to the above modification. If the toner hopper unit is replaced in the field,
replace the red idler gear in the new toner hopper with the white gear in the original toner
hopper unit.
The toner hopper unit part number will be therefore changed because of the gear
replacement and C-ring substitution. As the spare part of #A2943200 contains the white
gear, the old unit part can be replaced in the machines installed in the field. It is not
necessary to change the red gear to a white gear.

The following is the procedure packed in the accessory plastic bag as the temporary
solution. After step #35, remove the development unit and follow the instruction marked

SYMPTOM

SC495 is displayed while making copies. This symptom occurs soon after the machine
installation is completed.

CAUSE

When SP220 7 is performed at installation, the toner supply from the toner bank stops
before enough toner is supplied to the toner hopper.

This is because the toner hopper sensor tends to misdetect the toner amount before the
toner inside the toner hopper is stabilized.

SOLUTION

If this symptom occurs in the field, turn the main switch off and on. When enough toner is
supplied to the toner hopper, this problem will not reo ccur.

For a permanent countermeasure, the firmware has been changed to change the SP2207
operation. The firmware version was changed from Ver. 7.1 to Ver. 7.8.1.
The new firmware will be used from the January 2000 production.

Before modification:

While performing SP2207 (Forced toner supply), toner supply from the toner bank stops 4
minutes after the toner hopper sensor detects the toner.

After modification:

Toner supply stops 6 minutes after starting SP2207.
The part numbers (suffix) have been changed as follows:

Old (Ver 7.1) New (Ver 7.8.1)
P/N for the firmware (NA) A2945610B A2945610C
P/N for the firmware (EU) A2945660B A2945660C

It is recommended to install the new software (ver 7.8.1) before starting toner initial setting
with SP2207.

Noise (resonance) during copying

An audible resonance may occur during copying. To correct this, machines in production
have been modified as follow s:

Temporary countermeasure applied from December 1999 production:

The screws for attaching the right lower fusing stay (#10:A2944059) and the rear fusing
plate (#15: A2944057) have been inserted from the front side. They were previously
inserted from the rear side.

Permanent countermeasure for machines in production:

The screw holes in the rear fusing plate have been changed from 4.1 ± 0.1 mm and

4.1 ± 0.1 x 6 mm to 4 mm. The screw holes in the right lower fusing stay have been

changed from 4 mm to 4.1 ± 0.1 mm and 4.1 ± 0.1 x 6 mm. Please note that for the
permanent countermeasure, the insertion direction of the screws for the right lower fusing

Temporary Solution

The toner hopper contains red idler gear (A2943255: Idler Gear - 15Z). This gear reduces
the drive supplied to the toner hopper and prevents the oversupply of toner that occurs in
the initial period following installation.

The toner hopper gear for normal operation (White gear:AB013748: Joint Gear -15Z) and
a spare C-ring (07200060B: Retaining Ring - M6) have been packed in the accessory
plastic bag.

The procedure for the Toner Hopper Drive Gear Replacement (Joint Gear - 15Z) has been
packed in the accessory plastic bag. The procedure is also included on page 2/3 of this
bulletin.

Action required

Replace the red idler gear with the white gear after carrying out SP2-207-2 (Toner Bank
Toner Supply) by referring to the procedure for the Toner Hopper Drive Gear Replacement
(Joint Gear - 15Z) packed in the accessory plastic bag. The red idler gear is not necessary
after machine installation.

Permanent Solution

The permanent solution is basically the same as the temporary solution. To facilitate gear
replacement, the gear has been mounted with a screw (09513006B: Philips Screw With
Flat Washer - M3x6) instead of a C-ring. The procedure is included on page 3/3 of this

Note for SP2-207-2

Occasionally, SP2-207-2 finishes within 2 seconds or so. If this happens, perform
SP2-207-2 again. Normally this mode will continue for about 5 minutes.

Reason
The mylar attached to the agitator in the toner hopper cleans the surface of the
toner hopper sensor. This is done so that the sensor will accurately detect the
amount of toner in the hopper. If the sensor detects toner in the hopper when SP2­207-2 is initiated, the SP mode will not be carried out. This is to prevent toner from
being mistakenly supplied. However, when the mylar is rotated to clean the sensor
surface, the sensor may sometimes detect the mylar and judge that there is still
toner present. This may occur even if there is no toner in the hopper.

SYMPTOM

In the Japanese market, it has been reported that vertical black lines have a tendency to
appear in copy images after long continuous copy jobs (10 hours).

CAUSE

Toner is not completely removed by the cleaning blade due to paper dust that accumulates
on the cleaning blade after long continuous copying. During the continuous copying, the
drum motor does not stop and turn in reverse to clean the edge of the cleaning blade.

SOLUTION

On the production line (from March production: SICU&BCU version

The default settings of SP2506-1 and -2 will be changed from March production so that the
drum motor stops and turns in reverse every 30 minutes during continuous copying to
clean the blade edge.

Default setting: 2506-1 (changed from No to

Countermeasure in the field for machines produced up to February 2000:

Upgrade the SICU & BCU to V.7.28.1. Then, change the SP mode values as shown above
if the same symptom appears in the field.

Please note:

SP2-506-1 and –2

In order to activate the new default settings after you have installed the firmware, you must
enter the SP modes and manually change the settings to these new default values. After
this has been done, the machine will recognize these settings as the defaults.

If you change these two SP mode settings with versions older than 7.28.1, SC990 may
occur when printing out blank copies with the slip-sheet, cover sheet or chapter sheet
functions. Therefore, we recommend that you update the firmware to version V.7.28.1.

Continuous copy runs
Continuous copy runs are stopped for 5 or 6 seconds every 30 minutes to clean the edge

of the cleaning blade. However, the fusing unit maintains the ready temperature, as the
machine’s major internal mechanisms are not shut down during this interval.

Symptom 1:

Dog ear at the rear side of the leading edge.

Cause:

The Fusing Exit Guide is not properly set. There is a small gap at the Rear Magnet Catch.
In addition, the hot roller strippers are not in the proper position when the exit guide is
closed due to the mechanical load of the stripper sliding mechanism.

Solution:

Temporary Solution: From December production.

In order to minimize the sliding mechanical load, apply grease to the Stripper Release
Slider in the following places:

- The 2 shoulder screw holes on the Guide Plate

- The 5 projections on the surface of the Exit Guide Bracket

SYMPTOM

The open/close mechanism for the lower toner bottle cap does not work properly. In some
cases, the mechanism does not return the cap to the bottle, which causes the toner to spill
when the bottle is removed.
Note: This symptom occurs only with the lower toner bottle.

Occurrence conditions:

1. The lower toner bottle is not placed in the toner bank unit or the toner end

condition is detected for the lower toner bottle and:

2. The upper toner bottle is shaken several times before it is set.

CAUSE

If an operator shakes the bottle several times and then sets it in the machine, too much
toner will be supplied from the bottle. Normally, when the bottle cap is opened, about 30 to
40 g of toner is supplied. However, after the bottle has been shaken several times, this
amount can be up to 150 g.
In addition, if the upper bottle is installed first after having been shaken several times,
toner can get jammed in the lower bottle open/close mechanism, causing the mechanism
to lock.

SOLUTION

Production line (from April production: SICU&BCU version V.7.31.3)

-Software modification: If the upper toner bottle is set first, the machine LCD will instruct

the operator to install the lower toner bottle first.

-Decal: A caution decal [A] (A2941273) has been attached to the toner bank cover. Also,

step 3 of the existing toner bank decal [B] has been changed. This decal is attached to the
inner face of the toner bank cover.

The decal will read:

Do not shake toner bottle before setting.
Set lower toner bottle first.

How to distinguish the old type from the current type:
The angles of the cut-outs are 60 degrees different.

1. Remove the two gears shown in the picture (2 e-rings).

2. Remove the 2 pipes from the distribution case.

3. Loosen the two screws of the collection case and remove the lower pipe only.

Note: Place a sheet of paper or newspaper underneath the case, as toner from the pipe

will tend to leak.

4. Replace the lower pipe with the current type.

Note: Make sure that the toner drop hole is facing downward. However, it does not need

to be completely vertical (90 degrees). In addition, make sure that the U-groove on
the left face of the pipe is properly lined up with the projection on the case.

5. Return all other parts to their original positions.

Note: Make sure that the toner drop hole is in a lower position.
(It would be hard to see the hole from the front when the hole is in the proper position)

NOTE: After installing the new pipe, please double check that the drop hole is facing
downward. You can check this by looking at the pipe from the front. If you can barely see

the hole, it is in the proper position.

Introduction

To facilitate servicing the 105cpm (A295) model in the field, this RTB describes the
differences from the 85cpm (A294) model.

Major Parts

Fusing Lamps:

85 CPM AX430052 Fusing Lamp – 230V/530W

105 CPM AX430055 Fusing Lamp – 230V/630W

The wattage of the fusing lamps has been increased from 530 to 630W to improve fusing.
To distinguish these two lamps, the colors of the front harnesses [A] are as follows:

530W: Blue
630W: Red

The connectors for both the lamps have the same color. The following note for re­assembly has not been changed:

model.

198°C (A4/LT width or less) (105cpm)

➁➂ ➃➀➄

A294D627.WMF

The CPU turns on all three fusing lamps after the main switch is turned on, with a
one-second interval between each. This prevents the power from the AC line from
dropping too quickly.

When the fusing temperature reaches 155°C, the machine starts the process control data
initialization. However, this is not performed if the fusing temperature is already above
100°C at the time the main switch is turned on.

When the fusing temperature reaches 155°C, the copier starts fusing idling. However, the
idling is not performed if the fusing temperature is already above 100°C at the time the
main switch is turned on

When the temperature reaches 177°C, the warm-up period is completed and the “Ready”
indicator turns on. After this, the machine maintains a fusing temperature of 173°C (85
cpm model) and 178°°°°C (105cpm model).

In stand-by mode, one of the fusing lamps turns on intermittently in order to maintain ready
temperature. During the copy cycle, all three fusing lamps are used to maintain operating
temperature. The machine will turn the lamps on one at a time, with a one-second interval
between each.

echnical Bulletin

T

PAGE: 3/16

Model:

The CPU changes the interval that the fusing lamp is on depending on the temperature
measured by the thermistor. This is to maintain the fusing temperature as close to the
target value as possible.

Even if one of the lamps fails during copying, the machine will continue to function.
However, if it detects a broken lamp just after being switched on, an SC error occurs and
copying is not possible.

The machine uses the fusing lamp on/off control mode to maintain the fusing temperature
as close to the target value as possible. Even if thick paper mode is selected, fusing
temperature control does not change.

SP1-902-2 Default setting (42 seconds: 85 cpm, 34 seconds: 105 cpm):

Page 2-105, second paragraph:

Every 42 seconds (85cpm) or 34 seconds (105cpm) during printing, the oil
supply/cleaning web motor turns for 0.8 seconds to move the oil supply and cleaning web
felt. This 42 or 34-second cycle starts when the first copy reaches the fusing exit sensor
and ends 2 seconds after the last copy has passed this sensor. Both the motor rotation
cycle and on-time are adjusted by SP1-902-2 / 3.

Transfer Belt:

To achieve a higher copy speed than the 85cpm model, the transfer belt in the 105cpm
model is given a higher transfer current. With higher transfer current, black lines have a
greater tendency to appear in half-tone areas on the copy. To compensate for this, the
transfer belt used in the 105cpm model has a lower resistance.

To distinguish between the two transfer belt units, a seal is attached to the transfer belt
frame for the 105cpm model as shown. Note that the belt for the 105cpm model can also
be used for the 85cpm model.

The input voltage for the 85cpm model listed on page 3-2 of the Service Manual is
incorrect. Please correct your manuals as follows:
North America:
240V, 60 Hz: More than 10A (85cpm)
240V, 60 Hz: More than 12A (105cpm)
Europe/Asia:
220 ~240V, 50/60 Hz: More than 10A (85cpm)
220 ~240V, 50/60 Hz: More than 12A (105cpm)

Finisher ROM interchangeability

Although the finisher itself is interchangeable between both the 85cpm and 105cpm
models, the EPROM firmware must be updated to version E or newer for fnishers
produced before April 2000. The cut-in serial numbers for April 2000 production are as
follows:

L0670040001 (B302-14)

Charge Corona Bias Adjustment

1 Image Area

(Auto Process
Control OFF)

Adjusts the voltage applied to the grid plate
during copying when auto process control
is off.

Normally, there is no need to adjust this.

B

If there is an ID or TD sensor problem, the
machine goes into fixed toner supply mode.
After replacing the drum or charge corona
wire, change this value to the default.

2 ID Sensor

Pattern (Auto
Process Control
OFF)

Adjusts the voltage applied to the grid plate
when making the ID sensor pattern, when
auto process control is switched off.

B

Normally, there is no need to adjust this.
If the user wants high density copies, the
sensor pattern must be lighter, so this
voltage must be a higher negative voltage.

Margin adjustment for each scanned
original can be adjusted when the settings
of the following SP modes.
This change was a result of special
requests from the Japanese domestic
market. The following remarks will be
added as machine limitations. As a general
rule, the settings should not be changed.

• Printing productivity for the 1st set of

originals will be decreased after the
margin is adjusted.

• The margin in Magazine Mode and in

Combine Mode cannot be adjusted in
this SP mode.

• After scanning an original in the sample

copy mode or after select setting key is
pressed when printing file using the
document server, the margin adjust key
can be changed. However, the key
changed will not affect any margin
adjustment.

• When different margins are selected for

expectation.

• When the margin is changed in Tab

The finisher stacking ability depends on the paper load orientation (face-up or face-down).
For some paper brands, face-up produces better stacking and for other brands, face down
is better. The above decal instructs customers on loading paper in order to prevent
unnecessary service calls. Therefore, please use this decal for operator training.

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.

From April production

PAGE: 3/3

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.

Note

1. If toner sticks to the development roller, the bias voltage will increase in that area. This
may in turn cause dirty background on copies. Therefore, the development rollers
should be cleaned whenever the developer is replaced.

2. Paper jams may occur if toner sticks to the lower fusing exit guide. Therefore, the guide
should be cleaned at every PM visit.

3. If the hot roller stripper becomes dirty with toner or other particles, this may cause the
edge of the copy stack (paper trailing edge) to become dirty.

4. Paper dust on the duplex transport sensors and the duplex inverter sensor can cause
paper jams. Therefore, these sensors should be cleaned with a blower brush at every
PM visit.

This change was a result of special requests from
the Japanese domestic market. The following
remarks will be added as machine limitations. As
a general rule, the settings should not be
changed.

• Printing productivity for the 1st set of originals

will be decreased after the margin is adjusted.

• The margin in Magazine Mode and in

Combine Mode cannot be adjusted in this SP
mode.

• After scanning an original in the sample copy

mode or after the select setting key is pressed
when printing file using the document server,
the margin adjust key can be changed.
However, the key change will not affect any
margin adjustment.

• When different margins are selected for the

front original and rear original in Designate or
Chapter Mode (Duplex copy), copying may not
meet the user’s expectation.

• When the margin is changed in Tab Sheet in

Tab Mode, copying may not meet the user’s

expectation.
A registration sensor jam (SP7-504-63) with
duplex tray feed has been reported from the
Japanese field. When the paper buckle
(adjustment: SP1-003-3) in the registration nip is
too high, Z fold jams may occur. The tolerance
against registration motor torque has been
improved by this firmware upgrade. After updating
the firmware, check the registration from the
duplex tray (SP1-001-2).

SP1-002

Mis-detection of SC306 (Charge corona wire
cleaner connector is not connected). This
condition can be detected by SC305 (Charge
corona wire cleaner error 1) after updating the
firmware. SC306 was detected by a malfunction in
the Japanese field. The wire cleaner stopped in
the middle of the charge corona unit. Thus, a
black line appeared on the copy. After opening
and closing the copier door or switching the main
switch off and on, the cleaner returned to the
home position. The symptom was not duplicated
when the technicians visited the machine site.
We have learned that the new settings of SP 1­002 (side-to-side registration) are better. In order
to activate the new default settings after you have
installed the firmware, you must enter the SP
modes and manually change the settings to the
following new default values. After this has been
done, the machine will recognize these settings
as the defaults. If the side-to side registration is
within the specifications (2±1.5 mm), you do not
have to change the settings.

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.

Retrofit information

Reports have been received from the Japanese field of toner sticking to the surface of the
hot roller, causing the hot roller to require replacement before the PM interval (600K).

Cause:

We have found that the diameter of some web cleaning rollers (AE040029) was slightly
narrower in the central area, but the degree of variation was within specification (±0.3mm).
Due to this decreased diameter, the fusing cleaning ability at the central area tends to
decrease. This can cause some toner to remain on the hot roller, resulting in black lines,
black dots in the background and/or offset images.

Solution:

Replace the web cleaning roller and cleaning pressure springs with new parts. Please note
that both of these parts should be replaced together as a set.

SYMPTOM

The toner bottle cap remains in the toner chuck when the bottle is removed. This problem
can occur if a customer sets the upper toner bottle first at toner end and then removes the
bottle according to the displayed instructions. From the firmware version J, a message is
displayed instructing the user to set the lower toner bottle first at toner end.

CAUSE

Toner chuck layout.
The bottle cap can get caught by the toner chuck when the bottle is lifted upward and
removed.

SOLUTION

Temporary countermeasures:

1. Firmware version 7.44 (suffix L) displays the following caution message when the
machine reaches toner end. “Set or replace the lower toner bottle first”

2. A caution decal has been added to the inner cover of the toner bank.
