3.3.3 ADJUSTING THE PRINTING SIDE-TO-SIDE REGISTRATION

Adjust the laser beam main scan start position when the offset is large. The
procedure is as follows:
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
Main Frame
1st Optional Unit
2nd Optional Unit
3rd Optional Unit
4th Optional Unit
By-pass Feeder
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
