Descriptions on adjustment items
A. Document scan start position adjustment value (RRC-A)
Used to adjust the timing of outputting the image lead edge signal
(SCAN signal) after starting document scanning. (0 – 99: Refer-
ence value 50)
B. Resist roller clutch OFF timing adjustment value (RRC-B)
Used to adjust the timing of turning ON the resist roller after re-
ception of the resist signal (LD_START). (0 – 99: Reference value
50)
C. Rear edge void quantity adjustment value (DEN-B)
Used to set the void quantity on the rear edge. (0- 99: Reference
value 30)
D. Image loss quantity set value (IMAGE LOSS)
Used to set the image loss quantity. (0 – 99: reference value 20)
E. Lead edge void quantity set value (DEN-A)
Used to set the void quantity on the document lead edge. (0 – 99:
Reference value 20)
Adjustment procedure
1. Set the image loss quantity (IMAGE LOSS) and the paper lead
edge void quantity (DEN-A) to desired values. (0 – 99:
0.1mm/step)
2. Adjust the document scan start position (RRC_A) so that the im-
age loss quantity of an actual copy image becomes the set value
of procedure 1. (0 – 99: 0.29mm/step)
3. Adjust the resist roller clutch ON timing (RRC_B) so that the lead
edge void quantity of an actual copy image becomes the set value
of procedure 1. (0 – 99: 0.24mm/step)
4. Adjust the rear edge void quantity (DEN_B). (0 – 99: 0.1mm/step)

Function
(Purpose)
Used to adjust the copy image position and the void
area (image loss) on the print paper in the copy mode.

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 val-
ues (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.
