You can hold down the start key when the F1 is displayed it will show a sub code. The service manual for that model shows only one F1 code which is an F1-06. That is a shifter motor trouble. That is the section after the exit that offsets the copies.

You can reset the code with the instructions below. If the error recurrs then chech the exit section shidter for proper movement. You may require an on site technician to remedy this issue.

To reset the error code:
Hit <clear> <interrupt> <0> <interrupt>
14 <start>
