AR-M236/M276/M237/M277  ADJUSTMENTS 7 - 7

Note: Execute the procedure after completion of SIM 48-1-2.

1) Put a scale on the original table as shown below, and make a nor-

mal (100%) copy.

2) Compare the scale image and the actual scale.

If necessary, perform the following adjustment procedures.

3) Execute SIM 48-1-2.

4) Enter the set value and press the start key.

The set value is stored and a copy is made.

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

CCD unit is properly installed and that OC mode adjustment in
copying has been completed.

1) Put a scale on the original table as shown below, and make a nor-

mal (100%) copy 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 RSPF and make a normal (100%) copy.

3) Compare the scale image and the actual image.

If necessary, perform the following adjustment procedures.

4) Execute SIM 48-1-3.

5) After warm-up, shading is performed.

The current front surface sub scanning direction magnification ratio
correction value is displayed in two digits on the display section.

6) Enter the set value and press the start key.

The set value is stored and a copy is made.

7) Execute SIM 48-1-4.

The current back surface sub scanning direction magnification
ratio is displayed in two digits on the display section.

8) Enter the set value and press the start key.

The set value is stored and a copy is made.

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

paper off center is properly adjusted.

1) Place the center position adjustment test chart (sheet with a

straight line in the scan direction at the center) on the RSPF.

2) Make a normal copy from the manual paper feed tray, and check

the printed copy with the test chart.

If any adjustment is required, perform the following procedure. 

3) Execute SIM 50-12.

4) After warm-up, shading is performed and the current set value of

the off center adjustment is displayed on the display section in 2
digits.

5) Enter the set value and press the start key.

The set value is stored and a copy is made.

1) Execute SIM 41-3.

2) Gradually close the OC (SPF) from the full open position, and mea-

sure distance A when the display on the operation panel changes.
(See the figure below.)

Distance A = Table glass top - OC (RSPF) handle rib

OC (SPF) open/close position A: 125 – 225mm

3) If the distance is outside the specified range, adjust the open/close

sensor attachment plate position as shown below.

AR-M236/M276/M237/M277  ADJUSTMENTS 7 - 8

1) Set A3 (11" x 17") paper on the OC table.

(Keep the SPF (OC cover) open.)

2) Execute SIM 41-2.

3) Keep A=125mm, and execute SIM 41-4. (Do not put paper on the

table.)

4) Check the reaction with SIM 41-1. 

1) Fully open the RSPF.

2) Execute SIM 63-7.

3) When the operation panel displays "COMPLETE," the adjustment

is completed.

4) If the operation panel displays "ERROR," perform the following

measures.

• When the display is 0:

Check that the SPF is open.
Check that the lamp is ON. (If the lamp is OFF, check the MCU con-
nector.)
Check that the CCD harness is properly inserted into the MCU con-
nector.

• When the display is 281 or above:

1) Remove the table glass.

2) Remove the dark box.

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.

Used to adjust the RSPF scan position automatically. 

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.

Reason: To prevent erroneous detection by disturbing light of a 

fluorescent lamp, etc. 

Placing the black chart
   The black chart must cover
   this area.

Place only the black 
chart on the OC glass. 

For the RSPF standard-provision 
machine, check that the black 
chart covers the SPF glass. 

AR-M236/M276/M237/M277  ADJUSTMENTS 7 - 9

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.
