Intermittent aging

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.

Warmup time display

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.

Developing bias voltage 
output check

Used to out put the developing bias for 30 sec. For the adjustment procedure 
of the developing bias, refer to the previous descriptions.

2

Main charger voltage output 
check (Grid bias high mode)

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.

3

Main charger voltage output 
check (Grid bias low mode)

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.

6

Transfer charger voltage 
check

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.

Duplex motor forward rota-
tion operation check 

Used to rotate the duplex motor forward for 30 sec.

2

Duplex motor reverse rota-
tion operation check 
<Not Used>

Used to rotate the duplex motor reversely for 30 sec.
