After completion of warmup, counting is stopped and the ready lamp is
lighted. When the copy quantity is entered and the start key is pressed, copy-
ing is made to make the set quantity of copies. After 3 sec standby, copying is
made again to make the set quantity of copies. After that this operation is
repeated. The paper size does not matter.
Copy quantity setting: Copy quantity keys
Execute the simulation input with the copier side cover open, then close the
side cover, and the machine will starts warming up. Warm up time is counted
up every 2nd and it is displayed.
Used to out put the developing bias for 30 sec. For the adjustment procedure
of the developing bias, refer to the previous descriptions.
Used to output the main charger grid bias voltage at the high mode for 30 sec.
For the adjustment procedure of the main charger grid bias voltage, refer to
the previous descriptions.
Used to output the main charger grid bias voltage at the low mode for 30 sec.
For the adjustment procedure of the main charger grid bias voltage, refer to
the previous descriptions.
Used to output the transfer charger voltage for 30 sec. For the adjustment pro-
cedure of the transfer charger voltage, refer to the previous descriptions.
Used to rotate the duplex motor forward for 30 sec.
Used to rotate the duplex motor reversely for 30 sec.
The currently set duplex motor rotation speed set value is displayed. When
the set value is entered and the start key is pressed, the set value is stored.
Duplex motor rotation speed set value: Copy quantity keys
The currently set duplex motor switchback time set value is displayed. When
the set value is entered and the start key is pressed, the set value is stored.
Duplex motor switchback time set value: Copy quantity keys
Note: If this simulation is executed with the toner hopper installed, toner is
automatically supplied to the developer. Be careful of overtoner.
Used to cancel troubles except for U2.
Used to cancel U2 trouble.
Used to clear the maintenance counter.
Used to display the currently set maintenance cycle at the numbers shown at
right. When the set value is entered and the start key is pressed, the set value
is stored.
