50-2
Purpose Adjustment
Function (Purpose) Used to adjust the copy image position and
the image loss. (This simulation is a simpli-
fied version of SIM 50-1.)
Section
Operation/Procedure
1) Set item A (L1) and item B (L2) to 0.
2) Place a rule on the left edge of the document table, and make
a copy at a magnification ratio of 400%.
3) Measure the length of L1 and L2 on the copied image in the
unit of 0.1mm (referring to the figure below). Enter the adjust-
ment values of L1 x 10 and L2 x 10. Be sure to enter the both
adjustment values of L1 and L2.
L1: Distance from the lead edge of the copied image to 10mm
scale.
L2: Distance from the paper lead edge to the copy image lead
edge.

4) Press [EXECUTE] key. (The set value is saved.)
5) Make a copy at the magnification ratio of 100%, and adjust the
rear edge void.
