5993 008 Exe. Counter
Displays how many times the line position adjustment has been executed.
Counts up by +1 normally.
After a forced adjustment and a PCU replacement, it counts up +3
Also includes adjustments done at the factory.
5993 009 Error Counter
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.
