AR-M205 ADJUSTMENT 6-3
9) Measure the distance H between the paper lead edge and the image
print start position. Set the image print start position set value
(Exposure display <<AUTO+MAIN CASSETTE LAMP>> ON) again.
•1 step of the set value corresponds to about 0.1mm shift.
•Calculate the set value from the formula below.
•Calculate the set value from the formula below.
H/0.1(mm) = Image print start position set value
<H: Print start position measurement value (mm)>
Example:
5/0.1 = 50 = about 50
Note: If the set value is not obtained from the above formula, perform the
fine adjustment.
10) Set the lead edge void adjustment value (Exposure display
<<TEXT>> ON)* again.
•1 step of the set value corresponds to about 0.1mm shift.
•Calculate the set value from the formula below.
B/0.05 (mm) = Lead edge void adjustment value
<B: Lead edge void (mm)>
<B: Lead edge void (mm)>
Example:
When setting the lead edge void to 2.5mm
:2.5 /0.05 = about 50
:2.5 /0.05 = about 50
Note: If the set value is not obtained from the above formula, perform the
fine adjustment.

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
adjustment procedures.
4) Execute SIM 50-6.
5) Set the SPF lead edge position set value (Exposure display
<<AUTO>> ON) so that the same image is obtained as that obtained
in the previous OC image lead edge position adjustment.

(3)Main scanning direction (FR direction) distortion
adjustment
This adjustment must be performed in the following cases:
•When the mirror base drive wire is replaced.
•When the lamp unit, or No. 2/3 mirror holder is replaced.
•When the lamp unit, or No. 2/3 mirror holder is replaced.
•When a copy as shown is made.
1) Set A3 (11" x 17") white paper on the original table as shown below.
2) Open the original cover and make a normal (100%) copy.
3) Measure the width of the black background at the lead edge and at

(Lb) at the rear edge, there is no need to execute the following
procedures of 4) ~ 7).
4) Loosen the mirror base drive pulley fixing screw on the front frame
side or on the rear frame side.
5)Tighten the mirror base drive pulley fixing screw.
