TECHNICAL SERVICE BULLETIN
BULLETIN NUMBER: VT2105/2200 - 010 11/08/96
APPLICABLE MODEL: VT2200
SUBJECT: PAPER TABLE DRIVE ERROR (E-02)
SYMPTOM:
The Paper Feed Table is not driven. Service code E-02: (Paper Table Drive Error) is displayed.
CAUSE:
The DC motor that drives the table occasionally generates electrical noise when it starts rotating. This
electrical noise is input into the AC Drive Board and damages IC301 on the board.
The electrical noise tends to be generated when the motor is still new.
Since a DC motor of this type is used on the VT2200 & VT3800 models only, this problem does not occu r on
any other PRIPORT models.
FIELD COUNTERMEASURE:
For the field units, the Motor Relay Harness Kit has been registered as a service part (C2238131). Install
the kit as shown below.
NOTE: The Motor Relay Harness Kit: (C2238131) includes:
- One Relay Harness (includes the capacitors)
- One Ty-wrap
- One Grounding Screw (M4 x 6)
NOTE: To prevent the relay harness
from being caught by the gears,
firmly secure it with the Ty-wrap
as shown in the illustration.
PRODUCTION
COUNTERMEASURE:
To prevent the electrical noise from being generated, a harness which contains two capacitors will b e
installed between the AC Drive Board and DC motor from the August 1996 production.
