Resist quantity adjustment
Used to adjust the contact pressure of paper onto the copier resist roller and the RSPF resist roller.
(Operation/Procedure)
Used to adjust the contact pressure of paper onto the copier resist roller and the RSPF resist roller.
(Operation/Procedure)
1.
When this simulation is executed, the currently set value is displayed.
2.
In a machine with the multi paper feed unit installed, press the copy mode select key, and each setting mode
and display are changed sequentially.
In a machine with the single paper feed unit installed, press the copy mode select key, and each setting
mode and display are changed sequentially.
∗ The selected adjustment mode is indicated by the lamps as follows:

3.
Enter the adjustment value with the 10-key and press the SORT key. Then the set value is stored and a copy
is made.

SPF exposure correction
(Outline)
The APF exposure correction amount is adjusted by adjusting the change in Vref voltage for the OC mode.
(Operation/Procedure)
(Outline)
The APF exposure correction amount is adjusted by adjusting the change in Vref voltage for the OC mode.

1.
When this simulation is executed, the currently set value is displayed.
2.
Enter the adjustment value with the 10-key and press the start key. The entered value is stored and a copy is
made.
made.
∗ When the adjustment value is changed by 1, the D/A output is changed by +1 digit (dark) for OC
exposure. When it is changed by –1, the output is changed by –1 digit (light).
3.
When the clear key is pressed, the entered value is stored and the simulation mode is terminated.

Polygon motor check (HSYNC output check)
(Operation/Procedure)
When the START key is pressed, HSYNC is performed and the polygon motor is rotated for 30 sec.
At that time, the Zoom lamp is lighted for 100msec e3very time when HSYNC is detected.
(Operation/Procedure)
When the START key is pressed, HSYNC is performed and the polygon motor is rotated for 30 sec.
At that time, the Zoom lamp is lighted for 100msec e3very time when HSYNC is detected.

01
Shading check
(Outline)
Used to display the detection level of the white plate for shading. (Vref of AD conversion IC is fixed.)
(Operation/Procedure)
When the START key is pressed, the mirror base unit moves to the white plate for shading and Vref+ voltage of
AD conversion IC is set to 4.5V and Vref- voltage to 0.5V, and the copy lamp is lighted.
This state is kept for 10 sec, and the level of one pixel at the center is detected every second to display on the
value display section.

Self print only with the engine (1 by 2 mode)
(Outline)
Used to print in the 1 by 2 mode by ignoring the state of the optical system.
