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.
