AR-M350 ADJUSTMENTS 9-7
(2) DSPF scan magnification ratio
1) Set a chart of print pattern 70 on SPF/DSPF.
2) Make a copy. (In the case of DSPF back copy, make a single copy in
the duplex mode.)
3) Check that the output paper satisfies the specifications.
4) If not, adjust with SIM 48-1.
5) Make a copy again, and check that the output paper satisfies the
specifications.

The SPF main scan direction magnification ratio is common with OC.
L. OC scan lead edge adjustment
Before executing this adjustment, the following adjustment must have
been completed.
•OC scan magnification ratio adjustment
1) Set an original on the original table.
2) Enter SIM 50-1.
3) Make a copy.
4) Select the number to be set on the right of the LCD, and perform the
adjustment of each item.
5) Select "3: RRC-A" and change the value with 10-key to perform the
copy adjustment.
6) Select "4: RRC-B" so that the distance between the paper lead edge
and the copy image lead edge is within 3.0mm. Change the value
with 10-key and perform the copy adjustment.
7) Check that the lead edge shift is within 3.0mm. If not, perform the
fine adjustment of procedure 5) and 6).
8) Select "5: DEN-B" so that the white spot in the latter half of copy
(rear edge void) is within 3.0mm. Change the value with 10-key and
perform the copy adjustment.
(The rear void adjustment is changed by the step of 0.1mm.)
•When the rear edge void is too small, increase the value.
•When the rear edge void is too great, decrease the value.
9) Press [CA] key to cancel the simulation.
