MX-5001N ADJUSTMENTS 5 – 40
a. Adjustment procedures
1) Place the duplex adjustment chart shown below on the docu-
ment tray of the RSPF/DSPF.
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.
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.
If it is not within the specified range, perform the following pro-
cedures.
5) Enter the SIM48-1 mode.
(DSPF)
(RSPF)
* Items A, C, E: When the set value is increased by 1, the
magnification ratio is increased by 0.02%.
* Items B, D, F: 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 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 magni-
fication 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.
