RSPF scan position
automatic adjustment
[Function]
Place a A4 paper (white chart) so that it covers the RSPF scan glass and the OC glass
together, and close the RSPF.
When this simulation is executed, the current adjustment value is displayed as the initial display.
* Default is 1. Adjustment range is 1 – 99. Adjustment unit 1 = about 0.127mm
* If the values are kept as the default values, RSPF scan is not performed properly. The front
area of the proper scan position may be scanned.
In case of AUTO, press [START] key, and the mirror unit scans from the home position to the
SPF/RSPF scan position with the adjustment value displayed. The RSPF glass cover edge
position is calculated from the difference between the RSPF glass cover edge and the OC side
document glass CCD output level. If the adjustment is normal, the adjusted value is displayed. If
abnormal, the error LED lights up with the current set value displayed.
During the error LED is lighted, when [START] key is pressed again, execution is performed
again.
[Operation]
The operation is similar to simulation 46-01. (In MANUAL)

Polygon motor check
(HSYNC output check)
[Function]
When [ENTER]/[START] key is pressed, HSYNC is performed and the polygon motor is rotated
for 30sec.
At that time the COPY mode lamp is lighted for 100msec every time when HSYNC is detected.

Shading check
[Function]
Used to display the detection level of white plate for shading.
When [ENTER]/[START] key is pressed, the mirror base unit moves to the white plate for shad-
ing and the copy lamp is lighted.
When the light quantity is stabilized, revision is made for every second, and the level of one
pixel at the center of CCD which is not corrected is detected and the value is displayed in deci-
mal values on the LCD/display. (3 digits)
