[9] MAINTENANCE

AR-6020V
1.Necessary work for maintenance
A.Counter reset
When the drum cartridge, the transfer unit, or the fusing unit is
replaced with a new one, the initial detection function operates after
turning ON the power to reset each counter automatically.
When the machine is initialized during warming up, or when the
simulation is executed or the machine is turned OFF and the door
is opened before the machine enters the print (copy) ready state,
the initial detection function may not operate normally. Therefore,
never execute the simulation or never operate the machine such as
turning OFF the machine power and opening the door before the
machine enters the print (copy) ready state after replacing one of
the above parts and turning ON the power.
When the counter is not automatically reset, it must be reset manu-
ally.
Since the maintenance counter is not automatically reset, they
must be cleared by executing SIM20-01.
