AR-M236/M276/M237/M277 ADJUSTMENTS 7 - 9
3) Slide the lens unit toward the front side and attach it, then exe-
cute SIM.
• When the display is 143 or below:
1) Remove the table glass.
2) Remove the dark box.
3) Slide the lens unit toward the rear side and attach it, then exe-
cute SIM.
∗
When the lens unit is moved, execute the OC main scanning magni-
fication ratio auto adjustment, SIM 48-1-1.
∗
This adjustment is basically O.K. with SIM 63-7.
(15) RSPF scan position auto adjustment
[Function]
Used to adjust the RSPF scan position automatically.
[Operation]
1) With the RSPF or the OC cover open, place a chart of black back-
ground on the OC glass. (In the RSPF standard model, the RSPF
glass surface is included.)
∗
Use a black chart (UKOG-0011QSZZ) or prepare a chart as shown
below.
Chart size: 310 x 470, prepared with cutting sheet No. 791 (Black) or
an equivalent one.
2) Enter SIM53-08, and press [START] button.
Outline of SIM: The optical unit is shifted to recognize the bound-
ary between the OC glass and the RSPF glass cover.
With the same position as the reference, the RSPF scan position is
automatically adjusted.
<Note>
• After completion of the RSPF scan position auto adjustment, the
SPF lead edge adjustment must be executed. (Both surfaces)
• There must be no other sheet than the black chart on the glass sur-
face.
• Especially when in RSPF scan, the center area is scanned in the
main scan direction. Be careful to prevent external light from enter-
ing the scan area.
3) Check that the lead edge is not shifted. (Both surfaces)
(If the original lead edge adjustment has been made properly, even
when the scan position is shifted, it is followed automatically.)
4) Change the adjustment value of the RSPF scan end position.
(Change the adjustment value of SIM50-6-3 from 50 to 36.)
Change the number of steps for Pin off – scan end position from
1,014 to 986.
Be sure to execute this adjustment because an image may be cut
off during FAX transmission though copying is normally performed.
5) Change the initial value of the RSPF exposure adjustment (SIM46-
20) from 50 to 53.
(For the CCD exposure adjustment with RSPF, use the value of
the OC adjustment value +3.)
There are suffixes of –1 SPF and –2 RSPF. Change each of them.
C. Image density (exposure) adjustment
(1) Copy mode (SIM46-2)
1) Set a test chart (UKOG-0162FCZZ) on the OC table as shown
below.
2) Place three or more sheets of A3 (11" x 17") paper on the test
chart.
3) Execute SIM 46-2.
4) After warm-up, shading is performed and the current set value of
the density (exposure) level is displayed on the display section in 2
digits.
For mode selection, use the [10-key].
5) Change the set value with the [10-key] to adjust the copy image
density.
6) Make a copy and check that the specification below is satisfied.
Note: Place originals in the rear reference, and the test chart in the
front reference when adjusting the exposure.
<Adjustment specification>
Reason: To prevent erroneous detection by disturbing light of a
fluorescent lamp, etc.
