Since there is no service label in the machine, printing in the service mode setting value is not available either.
Hence, adjustment in the market is being performed. Please note that when the value service mode is modified, be sure to record the modified value.
When making a copier machine execute an operation using the service mode, be sure to remove the cable from the external controller or the network cable before
entering the service mode. Especially, when a print job is entered from an outside machine during the execution of FUNCTION mode (operation/checking mode), a
malfunction may occur and cause damage to the copier machine.
When using the service mode (ADJUST, FUNCTION, OPTION), be sure to turn the main power switch OFF/ON after exiting the service mode.
MEMO:
When PCB is replaced or RAM clearing is performed, the adjusted ADJUST and OPTION value will return to default value.
