BULLETIN NUMBER:      SS830/95/VT2130-041

02/04/94

APPLICABLE MODEL: VT2130

SUBJECT: REVERSE ROLLER CLUTCH

GENERAL:

REVERSE ROLLER CLUTCH - It has been
reported that a small horizontal white line may
appear 64mm from the leading edge of prints.
This occurs only when in photo mode and is
caused by a shock wave when the master is
clamped by the drum master clamper. To prevent
this white line, the Main PCB ROM has been
changed to delay the timing of the master
clamping. As a result of the new software, the
image on the prints is moved forward
approximately 2mm due to the slow response of
the current reverse roller and master clamper
mechanisms. To compensate for the new
software, the reverse roller clutch mechanism
has been changed from the combination of a
solenoid and a spring clutch to a magnetic
clutch. The parts listed on the part chart on page
2 have been changed to accommodate the new
style clutch.

NOTE:

The part number of the ROM and Main PCB for the VT2130 has been changed. The Main PCB has
not been changed except for the ROM. The old and new PCB’s are interchangeable.
