MR-2019/2018/MY-1034 ADJUSTMENTS 6 - 1
[6] ADJUSTMENTS
1. ADF/RADF scan position automatic
adjustment
Place a A4 paper (white chart) so that it covers the ADF scan glass
and the OC glass together, and close the ADF/RADF.
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, ADF/RADF 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 ADF/RADF scan position with the adjust-
ment value displayed. The ADF glass cover edge position is calcu-
lated from the difference between the ADF 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.
Operation
The operation is similar to simulation 46-01. (In MANUAL)
OK/ERR display in AUTO (LCD Model)
2. ADF/RADF mode sub scanning
direction magnification ratio
adjustment
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 ADF and make a copy in the normal
ratio (100%). (ADF model only)
Set the test chart on the RADF and make a duplex copy (D-D or
D-S) in the normal ratio (100%). (RADF 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 RADF, 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 ADF/RADF, copy is inhibited.
