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.
a. Distance (Document table mode 400%) up to the scale of 10mm from the image lead edge a L3
b. Distance from the paper lead edge to the image lead edge → L2
c. Distance from the image lead edge to the scale of 10mm (SPF mode 200%) → L3
* 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.
By setting the image loss, DEN-A, DEN-B (actual dimension (mm) x 10) and REAR LOSS (SPF) (actual dimension (mm))
directly, the lead edge image loss, the lead edge void area, the rear edge void area and the rear edge image loss (SPF)
can be set.

Note
When the image lead edge
position varied depending on
the copy magnification ratio,
change the set value.
When the image lead edge
position varied depending on
the copy magnification ratio,
change the set value.
The greater the set value is,
the greater the image loss is.
The greater the set value is,
the greater the void area is.
The greater the set value is,
the greater the void area is.
The greater the set value is,
the greater the image loss is.
