AR-M256/M257/M258/M316/M317/M318/5625/5631 ADJUSTMENTS, SETTING 7 - 3
B. Mechanism section
(1) Print start position adjustment
1) Execute SIM 50-5.
2) Touch the item to be adjusted.
The item and the currently set value are highlighted.
3) Press the [P] key.
The display is shifted to the copy menu.
4) Select the paper feed tray, the print density, and the duplex mode.
Enter the adjustment value with the 10-key.
5) Press the [START] key.
Copying is started.
6) Measure the distance H between the paper lead edge and the
image print start position. Set the image print start position set
value again.
• 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)>
∗
Fit the print edge with the paper edge, and perform the lead
edge adjustment.
Example:99 – 5/0.127 = 99 – 39.4 = about 59
Note:
FIf the set value is not obtained from the above formula, per-
form the fine adjustment.
7) Execute SIM 50-1-2 to adjust the main cassette lead edge void.
• 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)>
Example: When setting the lead edge void to 2.5mm:
2.5 /0.127 = about 20
<Adjustment specification>
[H: Print start position measurement value (mm),
B: Lead edge void (mm)]
(2) RSPF image lead edge position adjustment
1) Set a scale on the OC table as shown below.
Note:
Since the printed copy is used as a test chart, put the scale in
paralleled with the edge lines.
2) Make a copy, then use the copy output as an original to make an
RSPF copy again.
3) Check the copy output. If necessary, perform the following adjust-
ment procedures.
4) Execute SIM 50-6.
5) Set the RSPF lead edge position set value so that the same image
is obtained as that obtained in the previous OC image lead edge
position adjustment.
<Adjustment specification>
(3) Rear edge void adjustment
1) Set a scale as shown in the figure below.
2) Set the document size to A4 (8.5" x 11"), and make a copy at
100%.
3) If an adjustment is required, follow the procedures below.
4) Execute SIM 50-1 and set the density mode to DEN-B. The cur-
rently set adjustment value is displayed.
5) Enter the set value and press the start key.
