AR-RP9/SP9/AR-D33  ADJUSTMENTS  6 - 1

Place a A4 paper (white chart) so that it covers the SPF scan glass
and the OC glass together, and close the SPF/RSPF.

When simulation 53-08 is executed, the current adjustment value is
displayed as the initial display.

* Default is 1. Adjustment range is 1 – 99. Adjustment unit 1 =

about 0.127mm

* If the values are kept as the default values, SPF/RSPF scan is

not performed properly. The front area of the proper scan position
may be scanned.

In case of AUTO, press [START] key, and the mirror unit scans from
the home position to the SPF/RSPF scan position with the adjust-
ment value displayed. The SPF glass cover edge position is calcu-
lated from the difference between the SPF glass cover edge and
the OC side document glass CCD output level. If the adjustment is
normal, the adjusted value is displayed. If abnormal, the error LED
lights up with the current set value displayed.

During the error LED is lighted, when [START] key is pressed again,
execution is performed again.

The operation is similar to simulation 46-01. (In MANUAL)

OK/ERR display in AUTO (LCD Model)

Note: Before performing this adjustment, be sure to check that the

OC mode adjustment in copying has been completed.

1) Put a scale on the original table as shown below, and make a

normal copy (100%) on the front and the back surfaces to make
a test chart.

Note: Since the printed copy is used as a test chart, put the scale

in paralled with the edge lines.

2) Set the test chart on the SPF and make a copy in the normal

ratio (100%). (SPF model only)

Set the test chart on the RSPF and make a duplex copy (D-D or
D-S) in the normal ratio (100%). (RSPF model only)

3) Compare the scale image and the actual image.

If necessary, perform the following adjustment procedures.

4) Execute SIM 48-05.

5) The current sub scanning direction magnification ratio correc-

tion value is displayed in two digits on the display section.

6) Enter the set value and press the [START] key.

When adjusting the RSPF, use [2-SIDED COPY] key to select
single/duplex after entering the one page print mode, perform-
ing 2-page single copy.

* When there is no document in SPF/RSPF, copy is inhibited.
