Symptom
E532-0001 Error Code

Description
When E532-0001 occurred previously, the stapler unit became off the rail of the stapler mount. This error code has sometimes occurred since.


Items to Check
E532 is displayed when a failure of the stapler shift is detected.

Field Remedy
Considering the fact that the stapler unit becomes off the rail, there might be any problems in the stapler mount unit.
Check the following:
1. Stapler shift home position sensor (PI6) and its sensor flag
2. Whether the stapler unit moves smoothly.
3. Whether there is a warp in the mobile mount (FF6-1176) under the stapler unit.

For your information, there is a different case in the field where E532 occurred because the door switch was not actuated. So, check the door switch, too.

If the root cause is unable to be determined, replace the stapler mount unit (FG6-7478) with a new one.
