MX-3114N ADJUSTMENTS AND SETTINGS 5 – 81
18-B Image scanning position adjustment
(Manual adjustment) (RSPF mode)
This adjustment must be performed in the following cases:
* When the scan control PWB is replaced.
* When the EEPROM on the scan control PWB is replaced.
* When the scanner (reading) section is disassembled.
* When the scanner (reading) section is replaced.
* When U2 trouble occurs.
* When the RSPF section is disassembled.
* When the RSPF unit is replaced.
This simulation is to adjust the scanning position when scanning in
the RSPF mode.
If this adjustment is made improperly, the scanner stop position is
shifted from the specified position and a shade of the document
table may be reflected on the lead edge section of the scan image
in the RSPF mode.
1) Make a copy in the RSPF mode, and check for any shade on
the lead edge section of the copy image.
If there is any shade of the document table on the lead edge
section of the copy image, perform the following procedures.
2) Enter the SIM 53-8 mode, and press [MANUAL] key.
3) Enter an adjustment value with 10-key, and press [OK] key.
When the set value is increased, the distance from the home
position to the RSPF scanning position is increased. When the
set value is changed by 1, the scanning position is changed by
0.1mm.
Perform the procedures of 1) - 3) until a satisfactory result is
obtained.
After execution of this adjustment, be sure to execute ADJ 18C
Copy image position, image loss, void area adjustment (Manual
adjustment) (RSPF mode).
18-C Copy image position, image loss, void area
adjustment (Manual adjustment)
(RSPF mode)
This adjustment must be performed in the following cases:
* When the scan control PWB is replaced.
* When the EEPROM on the scan control PWB is replaced.
* When the scanner (reading) section is disassembled.
* When the scanner (reading) unit is replaced.
* When U2 trouble occurs.
* When the RSPF section is disassembled.
* When the RSPF unit is replaced.
a. Adjustment procedures
1) Prepare the adjustment chart.
The adjustment chart can be made by the following proce-
dures.
Use A4 (11" x 8.5") paper and draw arrow marks vertically and
horizontally on the front and the back surfaces.
At the same time, put marks of the lead edge, the trail edge,
the front end, and the rear end as well as the identification
marks of the front surface and the back surface.
2) Enter the SIM 50-6 mode.
