MX-M264U ADJUSTMENTS AND SETTINGS 5 – 36
4) Perform the image lead edge reference position adjustment.
Shift to the copy mode, and make a copy at each of 100% and
200% in the document table mode.
When the adjustment value of RRCA is proper, the lead edge
image from 4.0mm is not copied in either of 100% and 200%
copy scale.
If not, change and adjust the RRCA value.
(Adjust so that the lead edge image from 4.0mm is not copied
in either of different copy magnification ratios.)
Repeat the above procedures until a satisfactory result is
obtained.
5) Image loss adjustment
When the adjustment item of the image loss below is set to the
default value, it is adjusted to the standard state. If it is not in
the below standard state, or when it is set to a desired value,
change these adjustment items.
Void area: 4.0mm, Image loss: 4.0mm
When the adjustment value is increased, the image loss is
increased. When the adjustment value is decreased, the
image loss is decreased.
When the adjustment value is changed by 1, the void area is
changed by 0.1mm.
15-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.
CAUTION: After execution of this adjustment, be sure to execute
ADJ 15C Copy image position, image loss, void area
adjustment (Manual adjustment) (RSPF mode).
