Jam in left
accessory
Recommended action:
NOTE: This jam can occur if the carriage assembly motor is stopped. Whenever the carriage moves, a timeout
sequence of 3.5 seconds begins. If, within this time, the carriage does not reach its target position (home
position), the error code is triggered.
1 Print and analyze the event log to find out whether the error occurs repeatedly.
2 Make sure that the stapler is free of obstruction by moving it by hand from front to rear.
3 Make sure that the plastic wall from the accumulator is in place. If it is out-of-place, it will not allow the stapler
to complete its routine. If it is out of place, attempt to snap the plastic wall back into position. If it is broken, then
replace the accumulator assembly.
4 Replace the carriage assembly as needed.
5 Replace the controller PCA as needed.
