5.7.1 ADJUSTING THE PRINTING SIDE-TO-SIDE REGISTRATION
Adjust the laser beam main scan start position when the offset is large.
1. Make copies using the mainframe cassette, bypass feeder, and optional paper
feed units and check the amount that the image is shifted.
2. Adjust by changing the contents of the following addresses:
Source Address Default Unit
Main Frame 402466 0002H 0.5 mm
1st Optional Unit 402468 0000H 0.5 mm
2nd Optional Unit 40246A 0000H 0.5 mm
3rd Optional Unit 40246C 0000H 0.5 mm
4th Optional Unit 40246E 0000H 0.5 mm
By-pass Feeder 402470 0004H 0.5 mm
3. To move the start position to the right, increase the value.
To move the start position to the left, decrease the value.
For example:
• To move the start position to the right 2 mm (with respect to the default
value):
0002H + (2 / 0.5) H = 0006H
• To move the start position to the left 1 mm (with respect to the default
value):
0002H - (1 / 0.5) H = 0000H
