8 Exe. Counter
*BCU 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.
9 Error Counter
*BCU Displays how many times errors have been
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.
