CAUSE:
The distance between the jogger fences of the
duplex unit is smaller than the paper width. This
gives excess load to the paper stack in the
jogger unit and causes paper misfeeds.
The followings are possible causes:
1. Paper size is slightly larger than the standard size.
2. Improper jogger home position adjustment.
3. Improper jogger drive belt tension.
ACTION:
If the paper size is not the standard size, the procedure described in the manual would
not give the correct jogger fence positions. Please use the following adjustment procedure
for the jogger home position sensor in the field.
The tension spring for the jogger drive timing belt has not been implemented to any
mass-production units, so please change your manual for the jogger drive belt adjustment
as follows:

sleeve
PREPARED BY:
CHECKED
CLASSIFICATION:
❑ Action Required
■ Troubleshooting
❑ Retrofit Information
SYMPTOM:
Toner adheres on the surface of the lower development sleeve (about 18mm from the
front end) and it makes scratches on the drum. This shows black lines on the copy image.
CAUSE:
The cross mixing system mixes the
developer in the development unit. The
mixing vane [A] transports developer to the
rear and the auger [B] transports it to the
front.
The development motor turns at slower
speed after image development to remove
the developer on the development sleeves.
This operation reduces developer to the
mixing vane, however, the auger continues
turning and transports developer to the
front side of the development unit. This in-
creases developer amount at the paddle
roller front side area [C].
This uneven developer condition will normally be eliminated by the next copy cycle.
However, if copies are frequently made
one to each original, frequent slow down
operation continues to increase the
developer at the front side. The accumulated developer at the front side is brought
to the lower development sleeve and pack-
ed between the sleeve and the drum. This
large amount of developer makes friction
heat. Then, it melts and adheres toner on
the sleeve. Finally, accumulated adhered
toner on the sleeve damages the drum.

SUBJECT: Drum damage by adhered toner on the development

The toner adhesion occurs at about 30mm from the front end of the unit (18mm from the
sleeve end) for the following reasons:
1. The end of the auger guide [D] is located at about 30mm from the unit front end.
2. There is a peak of the magnetic force field of the lower sleeve located at that point.
COUNTERMEASURE:
To disperse the fallen developer from the
auger guide, the guide has been cut as
shown.
This modification has been applied from
July ’92 productions.
The auger guide cannot be replaced in the
field. This is because the guide is fixed on

Retrofit Information
A capability limitation of the F200 is that, due to the limitation of the power to the copier, it
has a low temperature idling mode.
To minimize the occurrence of the idling time, the following modifications have been
applied.
1. Fusing Lamps
To increase the fusing heat output during the copy cycle, the fusing lamp of 950W, which
is used during the copy cycle, has been changed to 1000W.
The other lamp (720W) was also changed to 670W to keep the total power consumption
the same as before. This is because all the ac components, such as the transformer and
circuit breaker, are designed for a total power of 1670W (1000+670W).

2. Software
To continue the copy run in low fusing temperature conditions as long as possible, the
software has been changed to lower the copy speed when the fusing temperature drops to
a certain temperature.
The copy speed is decreased by approximately 25% when the fusing temperature drops
below the lower limit temperature which is determined by the SP and User Tool settings
(see manual page 2- 96). For example, for the default settings, the slow-down copy cycle
will start when the temperature drops below 169°C.
Once the machine shifts to the slow-down copy mode, the mode is kept until the copy job
is finished even if the fusing temperature is recovered during the copy job.
Even if the slow-down mode is applied, the fusing temperature may drop in certain
conditions, such as A3 continuous copy run. A lower limit safety temperature has been
newly added to stop the copy run and to avoid any poor fusing problems when the
temperature drops below it. The lower limit safety temperature is lower than the lower limit
temperature by 5°C (164°C at default settings).
The following chart shows an ideal fusing temperature change in continuous copy run with
this new software.

There is no relationship between the new fusing lamps and the new software. You can use
the new EPROMs on the old machine without changing the fusing lamps and vice versa.
CAUTION:
The fusing lamps must be replaced as a set. If only the high output lamp is replaced to
1000W and old 720W lamp remains unchanged, the total current exceeds the rated values
of the ac components and may, in the worst case, cause damage and fire.

The fusing temperature display in SP mode of the F200 is different from that of the
previous models, such as those of the F20 series. This bulletin explains the temperature
display system of the F200 and revises the fusing temperature adjustment procedure.
1. Fusing Temperature Display and the Fusing Temperature Adjustment in SP mode
The displayed figure is calculated using the thermistor resistance and will not be affected
by the setting of the fusing temperature adjustment in SP mode.
The main PCB has a table to convert the thermistor resistance into a temperature figure.
The main PCB, then controls the fusing lamps according to the calculated figure, so that
the lamps are turned on at 195°C and off at 198°C.
The actual hot roller temperature is not the same as the temperature measured with the
machine’s thermistor because of the tolerance of the thermistor. Therefore, the fusing lamp
on/off temperature is compensated machine by the machine. This compensation is done
by changing the setting of the SP mode “Fusing Temperature Adjustment”,
The displayed figure is not the actual temperature, at the time the compensation is applied.
2. Fusing Temperature Adjustment
Please refer to the service manual page 5-94,
Add the following:
Adjustment Target :195 ± 1 °C

replaced the fusing thermistor.

The duplex jogger drive belt tension adjustment has been revised by the RTB-001 issued
on July 15, 1992,
The jogger fence drive belt tension mechanism has been reviewed to facilitate assembling
in the factory, and changed to an adjustment free mechanism as shown below,
1. Modified Items
The mounting holes of the timing pulley bracket
[A] has been enlarged and fixed by shoulder
screws [B].
A tension spring [C] has been added.
The width of the timing belt [D] has been
changed from 6mm to 4 mm to decrease the
drive load of the jogger fences.

SYMPTOM :
In multiple copy runs, image density goes down gradually even if small image area
or igin als ar e us ed.
CAUSE:
We have found that the toner supply amount when the Toner Density Selection setting in
the SP mod e (SP#10 p age 3) is at 30% is not enou gh for multip le co p ying of A4/ 81/2"x11"
size.
The toner is supplied by the toner supply roller, which has an A3/11" x 17" width. The
toner amount is correct for 30% area image, however, only toner at the A4/81/2"x11" area
(middle part) is consumed, and this causes low toner concentration at that part.

MODEL: F200 X/Y
COUNTERMEASURES:
Since the actual cause of the low ID problem in multiple copying was not clear, the factory
settin g o f th e ton er d ensity selec tio n was s elected as HIGH o nly o n t he Decem ber 1992
productions as a temporary solution.
From th e Jan uary 1993 p ro d uc tio n, th e fact or y s ettin g of the t on er den sity selec tio n in the
SP mod e has been returned to NORMAL and the toner supply amount has been changed
fro m 30% to 45%.
Please note that we will not modify the software to correct the toner supply amount d ata
for the 30% supply mode. This is because that you must check if the software is new or
old whenever you determine the proper toner supp ly amount setting for each machine.
In case of the low ID problems, the toner density selection in the SP mode is easily set to
HIGH or VHIGH b y field technicians. As for other models, toner scattering problems may
oc cu r if th e high er to ner den sity s electio ns are selec ted , even if to ner co nc entr atio n is
reasonably high in the development unit. There is a possibility of having toner adhering
pr ob lem o n th e d evelop m ent r o ller in an extr emely h igh to n er c on c entr atio n c o nd itio n even
if the machine has the new development unit with the modified auger guide (Refer to the
RTB-004).
To minimize the side effect pro blems, we recommend to return the toner density selection
to NORMAL and use the toner supply amount selection or ID selection in ADS mo de
instead (SP Special Features page 3), if customers need higher image density.
