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.
H/0.1(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: 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)>
Example: When setting the lead edge void to 2.5mm
:2.5 /0.05 = about 50
Note: If the set value is not obtained from the above formula, perform the
fine adjustment.

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.
