44 2 Used to display the reference value of the optical system dirt correction.
This value affects the process correction system. For details, refer to the
descriptions on the process correction system.
3 Used to display the reference value of the optical system dirt correction.
(Operation/procedure)
When the simulation key operation is performed, the current correction
amount is displayed in hexadecimal number on the COPIES SELECTED dis-
play.
The decimal number converted from the hexadecimal number shows the ac-
tually corrected copy lamp voltage.
Example --- 1d] : 2.9V correction
4 Used to display rotating time of the photoconductor drum.
This value affects the process correction system. For details, refer to the
descriptions on the process correction system.
(Operation/procedure)
When the simulation key operation is performed, the current rotating time of
the photoconductor drum is displayed in the unit of minute on the COPIES
SELECTED display.
10 Used to check the operation of the toner motor and its control circuit.
(Operation/procedure)
The toner motor turns on for 30 sec.
25 1 Used to check the operation of the sections other than the optical unit and to
check the operation of the toner density sensor.
(Operation/procedure)
The main motor rotates and the units connected to the main motor operate
accordingly. The output level of the toner density sensor is displayed on the
COPIES SELECTED display.
7 1 Warm-up time display and aging
When this simulation is executed, warm-up is started, and the warm-up time is
counted every second and displayed on the copy quantity display. At comple-
tion of warm-up, counting is stopped and RPL is lighted.
Press CA key to clear the warm-up time display, set the desired copy quantity
and press the PRINT button, and copying will be performed to make the set
quantity of copies.
4 Omitting warm-up
When this simulation is executed, the machine goes into the ready state (RPL
on).
6 Intermittent aging
When this simulation is executed, warm-up is started.
After completion of warm-up, set the copy quantity and press the PRINT
button, and copying will be performed to make the set quantity of copies.
14 Used to cancel troubles other than self diag U2 trouble code.
(Operation/procedure)
After cancellation of the trouble code, the simulation is also automatically
cancelled.
16 Used to cancel the self diag U2 trouble code.
(Operation/procedure)
After cancellation of the trouble code, the simulation is also automatically
cancelled.
