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
