Image Loss - Sharp AR-287 Service Manual

Descriptions on adjustment items
A. Distance from the image lead edge to 10mm of the scale (Platen
400%) (L1)
B. Distance from the paper lead edge to the image lead edge (L2)
C. IMAGE LOSS
D. DEN-A
E. DEN-B
Adjustment procedures
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. Set L1/L2 to 0.
3. Make a 400% copy with OC, and enter the shift quantity to L1/L2.
(0 – 999: 0.1mm/step)
4. Repeat procedure 3 so that the paper lead edge void quantity of
the actual copy image becomes the set value of procedure 1.
5. Adjust the rear edge void quantity (DEN_B). (0 – 99: 0.1mm/step)

Function Used to set the folding margin of center binding.
(Purpose)
Operation/ When this simulation is executed, the current set value
Procedure is displayed.
Under this state, the set value can be changed with the
10-key.
When the OK key is pressed, the currently set value is
stored in the EEPROM.
