It affects scanning (PC scanning, etc.) as well as copying.
6) Select an adjustment item of SPF (MAIN)/SPFB (MAIN) with the
scroll key.
7) Enter an 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 0.02%.

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.
state, copy check can be normally performed. When the
system key is pressed, the machine returns to the simula-

3. Sub scanning direction image
magnification ratio adjustment (RSPF
mode)
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 U2 trouble occurs.
*
When the copy magnification ratio is not matched.
*
When the RSPF is disassembled.
1) Place the duplex adjustment chart shown below on the docu-
ment tray of the RSPF. The adjustment chart is prepared by the
following procedures. Use A4 (11" x 8.5") paper, and put marks
on both sides and both surfaces of the paper at 10mm from
each edge.
following procedures. Use A4 (11" x 8.5") paper, and put marks
on both sides and both surfaces of the paper at 10mm from
each edge.
2) Make a duplex copy at the normal ratio on A4 paper.
3) Measure the images on the copy paper and the original images.
4) Obtain the image magnification ratio according to the following
formula:
Image magnification ratio = Original size / Original size x 100
(%)
(%)
Image magnification ratio = 99 / 100 x 100 = 99 (%)
If the image magnification ratio is within the specified range (100
+/- 0.8%), there is no need to perform the adjustment.
+/- 0.8%), there is no need to perform the adjustment.
If it is not within the specified range, perform the following pro-
cedures.
