22 Interrupt
*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.
