7 Result Displays the result of the latest line position
adjustment in 4 digits.
First 2 digits: Error detected on the front ID sensor
Last 2 digits: Error detected on the rear ID sensor
Refer to the Troubleshooting section for more
details about the two-digit codes.
8 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.
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.

BCU
Specifies the number of sheets to be printed
before a line position adjustment is done during a
print job.
[ 10 to 250 / 100 / 10 sheets/step ]
SP 5-993-4 must be set to ‘enabled’.
When the temperature difference meets the
conditions specified in SP5-993-3, the machine
starts counting the number of prints in the job. The
machine interrupts the print job and does the line
position adjustment if the number of prints
exceeds the number specified in this SP mode.
If the counted number of prints does not exceed
the number specified, the machine resets the
counter, then continues to monitor the
temperature and does the line position adjustment
next time.
