DETAILS OF MODIFICATION

It was reported that on some machines in the field, the image position varies. Although this is a v ery rare case, at worst this
happened after making about 200, 000 prints. On the problem machine, the one-way clutch inside the 2nd feed roller gear slips just
when the 2nd feed rollers start feeding a sheet. (The paper feed start timing is delayed.) This ma kes the image position vary, i.e.
move up or down in paper feed direction. After investigation, it was found that the grease inside t he one-way clutch changes in
quality and damage the inside surface of the clutch. The new 2nd feed roller gear contains a new ty pe of grease that does not
change in quality unlike the old one. To distinguish the new gear from the old one, a groove is mad e on the new gear.

DETAILS OF MODIFICATION

Before mass-production, it was found that a thin vertical black line (One CCD pixel’s width) appeare d on the
rear side of the copies when 64% (USA version machine) or 82% (The other versions machine) reduction
mode was selected. To prevent this, the magnification ratios at their reduction modes were slightly altered by
changing the PROM on the image processing board (For details, please refer to RTB No. 2 .). The suf fix at
the end of the part number was modified as follows:

USA version Image Processing Board : C2118033A to C2118033B
The other versions Image Processing Board : C2118002A to C2118002B
PROM (Common for all version) : C2118004 to C2118004A

As a permanent solution, some electrical components on the A/D conversion board have been changed as
follows:

MODIFICATION BULLETIN NO. 5 Page 2 of 4 ISSUED ON: September 15, ’91

IC601: 14072339 (IC - SN74LS241NS) to 14071600 (IC - SN74LS244NS)
R734: 16100079 (22KΩ tip type register) to 16302472 (4.7 K Ω tip type register)

The new A/D conversion board solves the above problem without the magnification ratio change. So, n ow
the PROM on the image processing board has been changed back to the previous type. The part numbers of
these parts are still the same, but their suffixes have been modified as follows for identification:

DETAILS OF MODIFICATION

A/D Conversion Board : C2038018A to C2038018B
USA version Image Processing Board : C2118033B to C2118033C
The other versions Image Processing Board : C2118002B to C2118002C
PROM : C2118004A to C2118004B

NOTE: 1. The PROM C2118004B has completely the same function as the no-suffix ROM (C2118004).

2. When an old type A/D conversion board is installed with a machine equipped the new PROM
(C2118004B), the black line will appear (only in the 64% or 82% reduction mode). So, the
PROM should be changed back to the old type (C2118004A) at the same time.

DETAILS OF MODIFICATION

The right guide plate of the priport VT2000 series was changed from that of the priport SS series in order to allow for the installation of
the tape dispenser unit. As a result, the appearance of the right guide plate was different from th e old one. This was visible especially
when the right and left guide plates were closed. (See figure)

Now the left guide plate has been changed to watch its appearance with that of the right guide plate . The difference between the new
and old one is only in the appearance of the backside (Interchangeability is O/O).
