Drum process speed increases 0.5% and
levels with the ITB rotation speed. As a
result, the main scan starting point shifts
approx 0.75mm to the leading edge on
both sides of the paper.
Image position must be readjusted in the
Adjustment Settings for Skilled Operators
menu to compensate the shift.

0
Cut-off frequency for drum revolution
control is reduced from 30Hz to 13Hz to
prevent resonance vibration.
4. Enter the Adjustment Settings for Skilled Operators menu and adjust the main
scan starting point in “0101: Adjust Image Position With Feed Direction” for both
front and back sides to compensate the image position shift as a result of the SP
modification in the previous step.
