To find out which problem has occurred, either:
•
See the Auto Service Call report that was sent to the service station by
the machine. This report lists a sub-code, as well as the error message;
this sub-code may help you find the problem.
Or, check the sub-code stored at RAM addresses 4805AF(H) and
4805B1(H).
•
Check the error code history using service function 03.
•
Try to clear the service call condition (for failures which are not related
to the fusing unit): switch the power off, wait 10 seconds, then switch
back on.
•
An SC-code is displayed on the LCD panel when the error occurs.
If the problem remains, work through the appropriate troubleshooting proce-
dure from the following pages.
After each troubleshooting attempt, reset the machine and try to operate it. If
the machine still does not work, continue troubleshooting.
