[10] MAINTENANCE AND OTHERS
1. Maintenance intervals and items to be serviced
Remove the printer cable from the connector before trying to service or repair a digital copier with an optional printing function, with its rear
cabinet removed.
If the copier is serviced or repaired with the printer cable connected, the printer could start operating due to a command that might be
accidentally sent from the personal computer, thus causing an accident.
