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 <EXP1> ON) 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)>
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)>
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.

adjustment in advance, and be sure to perform the second
print surface lead edge position adjustment and then the
lead edge void adjustment in this sequence.

b. SPF 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
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.
4) Execute SIM 50-1.
5) Set the SPF lead edge position set value (Exposure display
<MANUAL> ON) so that the same image is obtained as that ob-
tained in the previous OC image lead edge position adjustment.
