For the AR-160/161 also, perform the following procedures.
1) Loosen the developing doctor fixing screw A.
2) Insert a thickness gauge of 1.5mm to the three positions at 20mm
and 130mm from the both ends of the developing doctor as
shown.

3) Push the developing doctor in the arrow direction, and tighten the
developing doctor fixing screw. (Perform the same procedure for
the front and the rear frames.)

4) Check the clearance of the developing doctor. If it is within the
specified range, then fix the doctor fixing screw with screw lock.

When inserting a thickness gauge, be careful not to scratch the
developing doctor and the MG roller.

*
For the AR-160/161 also, perform the following procedures.
a. OC image lead edge position adjustment
Note: In advance to this adjustment, the sub scanning magnification
ratio adjustment must be performed.
1) Set a scale on the OC table as shown below.

2) Make a copy.
3) Check the copy output. If necessary, perform the following adjust-
ment procedures.
4) Execute SIM 50-1.
5) Set the OC lead edge position set value (Exposure display
<AUTO> ON) to “99.”
The OC image scanning start position is shifted inside the docu-
ment edge.
The OC image scanning start position is shifted inside the docu-
ment edge.
6) Set the main cassette lead edge void adjustment value (Exposure
display <PHOTO> ON) * to “1.”
The lead edge void becomes the minimum.

7) Set the print start position value (Exposure display <EXP1> ON)
to “99” and make a copy.
The print start position is shifted inside the document edge.
The print start position is shifted inside the document edge.
8) Measure the image loss R of the copied image. Enter the set
value of the image scanning lead edge position (Exposure display

•
1 step of the set value corresponds to about 0.127mm shift.
•
Calculate the set value from the formula below.

urement value (mm)>
urement value (mm)>
Example: 99 - 4/0.127 = 99 - 31.5 = about 67
Note: If the set value is not obtained from the above formula,
perform the fine adjustment.

•
1 step of the set value corresponds to about 0.127mm shift.
•
Calculate the set value from the formula below.
99 - H/0.127 (mm) = Image print start position set value <H: Print
start position measurement value (mm)>
start position measurement value (mm)>
Example: 99 - 5/0.127 = 99 - 39.4 = about 59
Note: If the set value is not obtained from the above formula,
perform the fine adjustment.
10)Set the main cassette lead edge void adjustment value (Exposure
display <PHOTO> ON)* again.
•
1 step of the set value corresponds to about 0.127mm shift.
•
Calculate the set value from the formula below.
B/0.127 (mm) = Lead edge void adjustment value <B: Lead edge
void (mm)>
void (mm)>
Example: When setting the lead edge void to 2.5mm:
2.5 /0.127 = about 20
Note: If the set value is not obtained from the above formula,
perform the fine adjustment.

Note: Since the printed copy is used as a test chart, put the scale in
paralled with the edge lines.
2) Make a copy, Then use the copy output as an original to make an
SPF copy again.
3) Check the copy output. If necessary, perform the following adjust-
ment procedures.
