Mode No.
(Class 1, 2, and 3)
Function / [ Setting ]
[Main Scan Reg Cor] Main-scan Registration Correction ([Color])
Specifies the correction to the main-scan length.
Main-scan length differs for each machine due to variations in parts used in the laser
optics housing unit. Fine adjustment of main-scan length is done at the factory on each
unit.
This SP mode is DFU except for when replacing the laser optics housing unit. When
replacing the unit, the data printed on the label attached to the new unit must be input with
this SP mode.
NOTE: When fine adjustment is required, the adjustment should be done with SP5-993-
010 to 012.

[Motor Reset] Mirror Positioning Motor Reset 995
1 Motor Reset Rotates the mirror position motors (CMY) by 250
pulses clockwise; then by 125 pulses
counterclockwise. This moves the mirrors back to
the initial position. Then, the settings of SP2-908-
002 to 004 are reset to 0.
When the line position adjustment fails, it is one of
possible causes when the mirror position motor
locks. Performing this SP mode can move the
mirrors back to the original position if it locks.
Then, do the forced line position adjustment (SP5-
993-002).
