Copy quality is directly affected by the key operator preventive maintenance.
THE COPIER FAILS TO OPERATE WHEN THE POWER ON SWITCH IS PRESSED
Check:
- The position of the on-off switch
- That the machine is plugged in properly.
COPIES ARE TOO LIGHT OR TOO DARK
Manual check:
- Move the EXPOSURE REGULATOR (A-17) to the right to make copies darker.
- Move the EXPOSURE REGULATOR (A-17) to the left to make copies lighter.
When the Automatic exposure control feature is used but copies are still to light or too dark,
proceed as follows:
- Turn the SETTING DEVICE in a clockwise direction to make
copies lighter.
- Turn the SETTING DEVICE in an anti-clockwise direction to
make copies darker.
COPIES ARE MARKED IN THE SAME PLACE
If marks occur in the same place on all copies, clean the copyboard glass and the cover.
