(Purpose)
Used to adjust the copy image position and the void area (image loss) on the print paper in the copy mode.
(Simple adjustment)
(This simulation allows the same simulation with SIM 50-1 more simply. )

This simulation is used to automatically adjust the image loss, the void area, and the image position by directly entering
the paper lead edge and the image shift (in the unit of 0.1mm) in 400% (200% for the SPF) copy.

The measurement value is multiplied with 10 to enter.
With the above procedure, the values of RRC-A and RRC-B in SIM 50-1 are automatically calculated and set.
By directly setting the values (actual dimensions [mm] x 10) of IMAGE LOSS, DEN-A and DEN-B, the lead edge image
loss, the lead edge void area, and the rear edge void area can be set.
