every section can be checked.

The service mode is selected when USER PRESET,
Multi-Copy key 3 and Original Size A3 keys are simultaneously pressed,
then F1 will appear in the display.
(If copier is abnormal, then F4 will appear in the display.)
To reset the service mode
The service mode is reset when USER PRESET and CLEAR/STOP keys are
pressed simultaneously.
NOTE: After servicing, if the copier is left in the F mode and shut off, when the
copier is turned ON again, it will still be in the F mode.
The reset program must be used to reset the F mode.
