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.

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
obtained in the previous OC image lead edge position adjustment.
