To find out which problem has occurred, either:
• See the Auto Service Call report 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.
Alternatively, check the sub-code stored at RAM address 8003C7(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 it back on (for
fusing unit errors, set printer switch 01 bit 0 to 1 before switching the machine
off)
• The LCD panel displays an SC code when the error occurs.
After each troubleshooting attempt, reset the machine and try to operate it. If the
machine still does not work, continue troubleshooting.
