Problem
PF motor out of step - the length of the PF motor internal encoder’s 
pulse is too long or too short compared to the regular pulse.

†

Solution
Make sure there is nothing blocking the grid rollers. If that does not 
solve the problem, check the PF motor encoder connection. If there 
still is a problem, try the following.

„

Check and adjust the PF Belt tension

„

Replace the PF motor

„

Replace the Main Board

†

Problem
PF motor overcurrent - Feedback from the PF motor (IC35) driver’s 10-
pin output (sensor signal) indicates that the PF motor’s current is 
irregular.

†

Solution

„

Replace the PF motor

„

Replace the Main Board

†

Problem
PF 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. The rotary encoder is activate for the 
predetermined “in-position time” and if the encoder sends a pulse, 
this means the carriage is moving even though it is supposed to be at 
a full stop, this generates an error.
