51 02 Resist quantity adjustment
Used to adjust the contact pressure of paper against the machine resist roller and the RSPF resist roller.
(Operating procedure)
When this simulation is executed, the current setup value is displayed.
Enter the adjustment value with the 10-key and press the PRINT switch, the entered set value will be saved and a copy will be made.
When the clear key is pressed, the entered value will be saved and the machine will exit from the simulation mode.

: Supported only for installing models, and skipped for not-installing models.
53 08 SPF scan position automatic adjustment
Place a black chart so that it covers the SPF scan glass and the OC glass, and execute the simulation with the OC cover open, the
mirror unit scans from the home position to the SPF scan position to identify the SPF glass cover edge position by the difference in the
CCD output levels of the SPF glass cover edge and the OC side document glass.
Default is 50. Adjustment range is 0 – 99. Adjustment increment: 1 = about 0.127mm
If this adjustment is performed properly, the adjustment value is displayed. If it is abnormal, the jam lamp lights up. If the adjustment is
not made properly, "– –" is displayed.
61 03 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 lit for 100msec for every 3 times that the HSYNC is detected.
63 01 Shading check
Used to display the detection level of the white board for shading.
(Operating procedure)
When the PRINT switch is pressed, the mirror base unit moves to the white board for shading to light the copy lamp. Under this state,
the level of one pixel at the CCD center which is not corrected for 10sec in 1 sec, and the result is displayed on the value display
section.
64 01 Self print
Print of one page is made regardless of the status of the optical system.
(Operating procedure)
When this simulation is executed, warm-up is performed and the ready lamp is lighted. Enter the code number with the 10-key, and
select the cassette with the cassette select key and press the PRINT switch, and paper feed operation will be made from the selected
cassette and printing of the selected pattern will be made. Printing is in 1by2 mode, or grid pattern.
