Shading Check; Spf Automatic Correction - Sharp AR-M207 Service Manual

Main Sub
code code
63 01

Shading check

Used to display the detection level when the lamp of the white plate for shading correction is lighted.
When the simulation code is entered, the initial window is displayed to urge execution. Press [OK] key or
[START] key to start the simulation. The contents of the operations are as follows:
1. The mirror base unit is shifted to the white plate for shading correction.
2. The copy lamp is lighted.
3. "0" is displayed until the copy lamp light quantity is stabilized.
4. When the light quantity is stabilized, the level of 1 pixel on the CCD center which is not corrected is
displayed in hexadecimal.
* The white level is displayed for about 10sec. The data update cycle is about 1sec.
5. After passing 10sec, the machine returns to the sub code input window.

SPF automatic correction

Used to adjust the SPF white correction start pixel position.
When the carriage or the platen glass is replace, this simulation must be executed.
When this simulation is executed, the initial window as shown below is displayed.
When [OK] key or [START] key is pressed with the OC cover open, the automatic adjustment is executed
and the position (which pixel from the CCD edge) of the exposure correction sheet (white Mylar) in the SPF
position is displayed.
After completion of adjustment, the result is saved to the EEPROM.
When the result is in the range of 93 - 299, it is judged as a success. If not, it is judged as an error. In case
of an error, the result is not saved to the EEPROM.

WHITE ADJUST
* Since this simulation detects the border line between the white Mylar (white) edge and the sky-shot
(black), if the simulation is executed with the SPF unit (OC cover) open, it is judged as an error.
* Since the adjustment value is the position of the border line, in order to execute white correction in an
actual SPF copy, the point is "Adjustment value - 34th pixel."
