To increase the durability, the material and surface treatment of the front
and rear flanges on the paddle roller [#43] are changed.
[For the black development unit]
At the same time, the rubber bushing [#67] is newly installed on the rear
side to ensure the seal function. Due to these changes, the rear side
plate [#12] is also changed. A retaining ring (C-ring M12) [#105] and the
bearing retainer [#68] are added on the rear frange of the puddle roller.
To get the space for the bearing retainer, the width of the gear - 44Z
(#17) is changed from 15.5mm + 14.5mm.
Note : * The old paddle roller and the old rear side plate are still
available for the machines with the old parts.
* When either the old paddle roller or the old rear side plate in the
black development unit is replaced with a new type replace the
other five parts with new ones as a set.

DETAILS OF MODIFICATION
To increase the tolerance of electrolytic intensity for EMI (VDE) standard, the following modificati on has been
applied to European models such as --25, 26, and --27. (There is no change for other models.)
1. Motor PCB and Process PCB
The printed circuit pattern on these PCB’s is changed from single layer to multi-layer.
2. Shielding plate
The shielding plate used in European models is eliminated.
3. Motor control harness and change power pack
A ferrite core is added to:
1) the high voltage cable for PCC on the charge power pack
2) the motor control harness inbetween the main PCB and the 3 servo PCB.
MODIFICATION BULLETIN NO. 17 Page 3 of 4 ISSUED ON: Jan. 31, ’91
4. Rear Cover
The conductive painting layer inside the rear cover is elminated. As a result, the rear cover used in 115V models
is commonly used for European models, too.

DETAILS OF MODIFICATION
To increase the strength of the rear side plate, the support plate [A] with two tapping screw - M4x8 [B] have been added
between the rear side plate [C] and the optics rear side plate [D]. These two rear side plates have been changed, but they are
not the service parts. To ensure correct mounting of the OPC drum motor, the shape of the hook and the screw hole of the rear
drum bracket have been changed. A similar change has been made on the drum holder shown next page.

To facilitate servicing, the shape of the drum stay and the erase lamp have been changed as shown in the figure below:
The erase lamp holder has been added to the new drum stay. With new drum stay and erase lamp holder it becomes possible to
remove the erase lamp by removing the erase lamp holder (1 screw). (With the old drum stay, it is n ecessary to remove the drum stay (3

Erase Lamp Holder can not be installed due
to shape of erase lamp. Instead of installing
the holder, please be sure to confirm the
Erase Lamp being set securely.
The best way is to install Drum Stay with Erase Lamp
Holder (1 screw). If Erase Lamp Holder is not available
immediately, install only the Drum Stay. In this case, please
be sure to confirm the Erase Lamp being set securely.

DETAILS OF MODIFICATION
When the machine is in the stand by condition, the current is output constantly to the IC on the 3 s ervomotor
control board to keep the home position of the transfer drum, and the IC generates heat. (The funct ion of
this IC is driving the transfer drum.)
To improve IC’s durability, the software program has been changed. In the stand by condition, the c urrent
out put to the IC has been reduced to decrease heat at the IC.
