AL-2041 SIMULATION, TROUBLE CODES 10 - 21
51
02
Resist quantity adjustment
[Function]
Used to adjust the contact pressure of the main unit resist roller and the SPF resist roller onto
paper. When this simulation is executed, the current set value is displayed.
The adjustment modes can be selected by pressing [Exposure mode selector] key.
Enter the adjustment value with [ ] [ ] key and press [START] key to save the set value and
make a copy.
[Operation]
The operation is similar to simulation 46-01.
53
08
SPF scan position automatic
adjustment
(excluding AL-2021)
[Function]
Place a A4 paper (white chart) so that it covers the SPF scan glass and the OC glass together,
and close the SPF.
When this simulation is executed, the current adjustment value is displayed as the initial display.
* Default is 50. Adjustment range is 1 – 99. Adjustment unit 1 = about 0.127mm
In case of AUTO, press [START] key, and the mirror unit scans from the home position to the
SPF scan position with the adjustment value displayed. The SPF glass cover edge position is
calculated from the difference between the SPF glass cover edge and the OC side document
glass CCD output level. If the adjustment is normal, the adjusted value is displayed. If abnor-
mal, the JAM LED lights up with the current set value displayed.
During the JAM LED is lighted, when [START] key is pressed again, execution is performed
again.
[Operation]
The operation is similar to simulation 46-01. (In MANUAL)
61
03
Polygon motor check
(HSYNC output check)
[Function]
When [START] key is pressed, HSYNC is performed and the polygon motor is rotated for 30sec.
At that time, the ZOOM lamp is lighted for 100msec every time when HSYNC is detected.
The sub code display is lighted. (After completion of execution, it blinks.)
63
01
Shading check
[Function]
Used to display the detection level of white plate for shading.
When [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 LED.
