DETAILS OF MODIFICATION
A few thin horizontal white lines may sometimes appear on prints (approximately one CCD pixel width line)
This is caused by electrical noise generated in the flat cable ferrite core between the main board a nd image
processing board. The electrical noise affects a signal line on the thermal head drive board. To c lear the
electrical noise a strip of an electrical conductive tape has been added inside the flat cable. (Th e previous
type flat cable # C2098151 is still used for the USA version machines.)

When removing the paper feed front plate, it is necessory to disconnect two harness for the paper re turn motor
and separation plate pressure release solenoid. To facilitate servicing at that time, the DC drive harness has been
changed. Now the connector (CN172) can be disconnected near the paper feed front plate.

DETAILS OF MODIFICATION
The left and right fluorescent lamp covers have been changed so that an operator can grip them easily when opening the
scanner unit. For the right cover, the improvement is minor and the part number has not been changed (#C2103219 for NRG
USA/TAIWAN version, #C2103220 for NRG European version, #C2103223 for Ricoh version). However, the left fluorescent
lamp cover has to be replaced with the cover support bracket (# C2093169) at the same time, so its part number has been
changed as described on the first page.

MODIFICATION BULLETIN NO. 6 Page 2 of 3ISSUED ON: September 15, ’91
DETAILS OF MODIFICATION
When an operator moves the original side guides to adjust them to the original width, the slider sea ls (mylar strips : C2093093) tend
to be caught by the edge of the side fence gears (See figure). This may cause the operation of the original side guides to be hard.
Slider Seal
Hit Point
To make the original guides move smoother, the shape of the side fence gears has been changed as shown in the below figure. At the
same time, the sensor shielding plate (Index 17) has been secured with the side fence gears by a screw (Index 18) in order to remove play.
