AR-203E/5420/M200/M201  SIMULATION, TROUBLE CODES  10 - 31

53

08

SPF/RSPF scan position 
automatic adjustment (Only 
the AR-203E/M200/M201 
with the SPF/RSPF 
installed)

[Function]
Place a A4 paper (white chart) so that it covers the SPF/RSPF scan glass and the OC glass
together, and close the SPF/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, SPF/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 SPF/RSPF glass cover edge
position is calculated from the difference between the SPF/RSPF glass cover edge and the OC
side document glass CCD output level. If the adjustment is normal, the adjusted value is dis-
played. 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)

OK/ERR display in AUTO

03

Polygon motor check 
(HSYNC output check)

[Function]
When [OK]/[ENTER]/[START] key is pressed, HSYNC is performed and the polygon motor is
rotated for 30sec.

At that time, the ZOOM lamp (or the COPY mode lamp for the AR-M200/M201) is lighted for
100msec every time when HSYNC is detected.

63

01

Shading check

[Function]
Used to display the detection level of white plate for shading.

When [OK]/[ENTER]/[START] key is pressed, the mirror base unit moves to the white plate for
shading 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)
