AR-BC320 SIMULATION 9 - 61
A. Document lead edge reference position --- (RRC-A) This set
value is used to adjust timing from when the document
scanning is started to when the image lead edge signal
(Set range: 1 – 80) (Default value: 50)
B. Paper lead edge position --- (RRC-B) Used to adjust timing of
turning on the resist roller after receiving the resist signal
(LD_START).
(Set range: 1 – 99) (Default value: 50)
C. Lead edge void area --- (DEN-A) Used to specify the void area
at the lead edge of the document.
(Set range: 1 – 99) (Default value: 40)
D. Rear edge void area --- (DEN-B) Used to specify the void area
at the rear edge of the document.
(Set range: 1 – 99) (Default value: 40)
E. Lead edge image loss --- (IMAGE LOSS) Used to specify the
image loss.
(Set range: 0 – 99) (Default value: 40)
This simulation is used to perform the lead edge adjustment by
directly entering the lead edge shift in 400% copy.
(Default values)
A. Document lead edge reference position --- (L1) 240
B. Paper lead edge position --- (L2) 40
C. Lead edge void area --- (DEN-A) 40
D. Rear edge void area --- (DEN-B) 40
E. IMAGE LOSS --- 40
2. Enter the adjustment value of the selected point with the 10-
key, and press the [OK] key. (The entered adjustment value is
set. The [EXECUTE] key or the scroll key can be used instead
of the [OK] key in the above procedure.)
3. Select the paper feed mode.
4. Press the [EXECUTE] key.
The test pattern corresponding to the entered adjustment value is
printed.
When the adjustment value of item A (DEN-C) is decreased by 1,
the print start position in the sub scanning direction shifts
0.125mm toward the paper lead edge.
When the adjustment value of item B (DEN-B) is decreased by 1,
the print start position in the sub scanning direction shifts
0.125mm toward the paper rear edge.
