detected during the line position adjustment.
The way that the auto line position adjustment is done can be adjusted using the following
SP modes (SP5-993-010 to 021). These are coefficients used for the adjustment.
Normally, do not change except if the automatic adjustment gives poor results immediately
after installing a new optics housing unit. Change the value then do a forced line position
adjustment (SP 5-993-2) to check the effects of the changes.
Example: If magenta is always shifted one dot to the left, reduce 5-993-11 by 1.
