(Exposure display <EXP1> ON) again.
(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)>
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, per-
form the fine adjustment.
10) Set the main cassette lead edge void adjustment value (Exposure

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)>
void (mm)>
Example: When setting the lead edge void to 2.5mm:
