MX-RP19 ADJUSTMENTS 4 – 4
5) Enter the SIM 48-1 mode.
* Items A, C, E: When the set value is increased by 1, the
magnification ratio is increased by 0.02%.
* Items B, D: When the set value is increased by 1, the
magnification ratio is increased by 0.1%.
* It affects scanning (PC scanning, etc.) as well as copying.
6) Select an adjustment item with the scroll key.
7) Enter an image magnification ratio adjustment value with 10-
key, and press [OK] key.
When the adjustment value is increased, the image magnifica-
tion ratio is increased. When the adjustment value is changed
by 1, the image magnification ratio is changed by 0.01%.

by 1, the image magnification ratio is changed by 0.01%.
Repeat the procedures of 1) - 7) until a satisfactory result is
obtained.

NOTE: When [CLOSE] key is pressed in this simulation mode, the
machine goes into the normal operation mode. Under this
state, copy check can be normally performed. When the
system key is pressed, the machine returns to the simula-
tion mode.

4. Scan image off-center 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.
NOTE: To execute this adjustment, it is required that the Scan
image off-center adjustment (Document table mode) must
have been properly adjusted.

1) Prepare the adjustment chart.
Draw a line at the center of the front surface and the back sur-
face of A4 (11" x 8.5") paper in parallel with the paper transport
direction.
face of A4 (11" x 8.5") paper in parallel with the paper transport
direction.
2) Set the adjustment chart to the RSPF.
3) Make a duplex copy in the normal magnification ratio from the
manual paper feed tray, and check the image position on the
front surface and the back surface of the copy paper.

If the difference is within the range of 0 +/- 2.7mmm there is no
need to perform the adjustment. If the adjustment is required,
perform the following procedures.
