Troubleshooting 43
SERVICE REQ. 00010006
Problem
CR motor overcurrent
Feedback from the CR motor driver (IC33) indicates that the CR motor’s
current is irregular.
Solution

SERVICE REQ. 00010007
Problem
CR in-position time-out
The in-position time is the amount of time the printer waits to make sure the
carriage is not moving when the carriage comes to a stop. If the linear
encoder sends a pulse during the in-position time, then the carriage is
moving even though it’s supposed to be at a full stop, and this generates
an error.
Solution
Replace the linear encoder sensor
Replace the CR motor
Replace the Main Board
