8

1

Used to check and adjust the operation of the developing bias
voltage in each print mode and the control circuit. (for OPC
drum type B)

2

Used to check and adjust the operation of the main charger
grid voltage in each print mode and the control circuit. (for
OPC drum type B)

6

Used to check and adjust the transfer charger current and the
control circuit.

7

Used to check and adjust the operation of the separation
charger voltage and its control circuit.

22

1

Used to check the print out count of each section in each
operation mode. 
(Used to check the maintenance timing.)

6

Used to output the list of the setting and adjustment data
(simulations, counters).

26

10

Used to allow entry of the software key input for the network
scanner. 

12

Used to enter the Diagnosis function key input.

13

After completion of copier job in copier interruption during a
printer job, the print job is resumed in synchronization with the
auto clear timer (key operation) setup time [10-240]. By
making the setup below, the print job is resumed in 0 sec.
(However, the auto clear function is enabled with the setup
time of key operation. Also, this simulation and auto clear are
not synchronized.)

22

Used to set the specification (language display) for the
destination. (Excluding the Japan models.)

32

When the variable speed fan motor is in the ready state and
the process temperature is in the range of 36° – 45°, the
PWM duty is set in percentage.

44

Used to set the model of the unit which is connected to the
SCSI I/F of ICU PWB.

52

Used to set whether white paper discharge count up is
performed or not.
("White paper" means insertion paper in the OHP insertion
paper mode (without copy), cover paper in the cover paper
insertion mode (without copy)/back cover, and white paper in
the duplex exit mode (CA etc.).)

50

1

Used to adjust the copy image position and the void area
(image loss) on the print paper in the copy mode. (The same
adjustment can be made with SIM 50-2 (simple method).)

2

Used to adjust the copy image position and the void area
(image loss) on the print paper in the copy mode. (Simple
adjustment)
(This simulation allows the same simulation with SIM 50-1
more simply. )

26

Used to set the folding margin of center binding.

51

3

Used to set the clutch OFF time. (AR-507 Europe and U.K.
only)

61

2

Used to adjust the scanner (exposure) laser power (absolute
value) in the copy mode.

4

Used to adjust the scanner (exposure) laser power (absolute
value) in the printer mode. (For Photoconductor type B)

67

18

Used to clear the application data area of the Network
Scanner of the Flash ROM.

Purpose

Adjustment/Operation test/check

Function
(Purpose)

Used to check the operation of the developing bias volt-
age in each print mode and its control circuit. (For OPC
drum type B)

Operation/
Procedure

(The developing bias output voltage of each print mode
can be adjusted and checked.) 

1. Select the print mode with [

­

] key and [

¯

] key.

2. Enter the adjustment value with the 10-key pad.

3. Press the [EXECUTE] key.

The [EXECUTE] key is highlighted, the adjustment value entered in
procedure 2 is set, and the voltage corresponding to the set value is
supplied.
After supplying the voltage for 30 sec, the [EXECUTE] key returns to
the normal display.
If the [EXECUTE] key is pressed while the voltage is supplied, the
voltage output is stopped and the [EXECUTE] key returns to the nor-
mal display.
