2) Press [START] key.

The transfer belt performs contact/separation with the OPC drum.

Press [CUSTOM SETTINGS] key to stop the operation.

NOTE: Before disassembling the transfer unit, use this simulation to

separate the transfer unit from the OPC drum.

1) Select the number corresponding to the operating condition of

aging with 10-key.

The combined mode of 0 - 6 mode and 10, 20, or 30 mode can be
set.

In that case, the number corresponding to one of 0 - 6 mode and
the number corresponding to one of 10, 10, and 30 mode are
added and the sum number is entered.

2) Press [START] key.

The condition selected in procedure 1) is set.

The setting of this simulation is kept valid until the power is turned off.

Press [START] key, and the operation 
is started.
