MX-B382/B402  SIMULATION  5 – 54

 

50-2

Adjustment

Function (Purpose) Used to adjust the copy image position and

the image loss. (This simulation is a simpli-
fied version of SIM 50-1).

Operation/Procedure
The magnification ratio adjustment in the sub scanning direction
must be executed in advance. (SIM48-01)
1)

Set item A (L1) and item B (L2) to 0.

2)

Place a rule on the left edge of the document table, and make
a copy at a magnification ratio of 200%.

3)

Measure the length of L1 and L2 on the copied image in the
unit of 0.1mm (referring to the figure below). Enter the adjust-
ment values of L1 x 10 and L2 x 10. Be sure to enter the both
adjustment values of L1 and L2.
L1: Distance from the lead edge of the copied image to 10mm
scale.
L2: Distance from the paper lead edge to the copy image lead
edge.

4)

Press [EXECUTE] key. (The set value is saved.)

5)

Make a copy at the magnification ratio of 100%, and adjust the
lead edge void.

Same as the adjusted items of SIM50-01 except for A and B.
The values adjusted with A and B are reflected to the document
lead edge reference position (RRC-A) of SIM50-01 and all the
paper lead edge positions (RRCB-**).
All adjustment items: 1 step = 0.1mm change

 

50-5

Adjustment

Function (Purpose) Used to adjust the print lead edge image

position. (PRINTER MODE)

Operation/Procedure
1)

Select a target adjustment item (DEN-C) with [

] [] key.

2)

Enter the adjustment value using the 10-key.

3)

Press [EXECUTE] 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: 3.0

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.
