1 - 4. (RRC-B) Timing of paper (resist roller ON) for the image posi-
tion on the transfer belt is adjusted. (0.1mm/step)

*

When the value is decreased, the timing is delayed. When
the value is increased, the timing is advanced.

5. (DEN-A) The paper lead edge void amount is adjusted. (0.1mm/
step)

*

When the value is increased, the void is increased.

6. (DEN-B) The paper rear edge void amount is adjusted. (0.1mm/
step)

*

When the value is increased, the void is increased.

Adjustment

Used to adjust the print lead edge image
position. (PRINTER MODE)

1) Select a target adjustment item (DEN-C) with Arrow key.

2) Enter the adjustment value using the 10 keys.

3) Press [OK] key.

The set value is saved, and the adjustment check pattern is
printed.

4) Measure the distance from the paper lead edge the adjustment

pattern to the image lead edge, and check to confirm that it is in
the standard adjustment value range.

Standard reference value: 4.0 +/- 2.0mm

When the adjustment value is increased, the distance from the
paper lead edge to the image lead edge is increased. When the
adjustment value is decreased, the distanced is decreased.

When the set value is changed by 1, the distance is changed by
about 0.1mm.

When the adjustment value is increased, the distance from the paper lead edge to the image lead edge is increased. When the adjustment
value is decreased, the distance from the paper lead edge to the image lead edge is decreased.

When the set value is changed by 1, the distance is changed by about 0.1mm.

Adjustment

Used to adjust the black print image magni-
fication ratio and the off-center position.
(The adjustment is made separately for
each paper feed section.)

1)

Select an item to be set with Arrow keys.

2)

Enter the set value with 10 keys.

3)

Press [OK] key. 

The set value in step 2) is saved.

Item 1: When the set value is increased, the BK image magnification ratio in the main scanning direction is increased. When the set value is
decreased, the image magnification ratio is decreased.

Item 2 - 7: When the adjustment value is increased, it is shifted to the front frame side. When the adjustment value is decreased, it is shifted to
the rear frame side.

Item 2 - 7: 1 step = 0.1mm change

Adjustment

Used to adjust the image registration. (Main

adjustment)/OPC drum phase adjustment
(Auto adjustment)

1) Press [OK] key. 

All drum motors are moved and the adjustment starts.  

NOTE: The contents of the following list are mainly used by the
technical division, and are not necessary for the market.

*1: The color image skew adjustment is performed according to this
display value.

When "R" is displayed in front of the value, turn and click the skew
adjustment screw (LSU) clockwise by the value.

When "L" is displayed in front of the value, turn and click the skew
adjustment screw (LSU) counterclockwise by the value.

At that time, the values under the decimal point are rounded.
