1917 Side-to-Side Registration Offset
The center of the paper cassette is the reference point for the alignment of all paper
sizes in the paper cassettes. However, the amount of skew can be different for some
paper sizes due to the positions of the side fences the number of feed rollers that touch
the paper. After buckle adjustment, the machine corrects skew in the main scan
direction (side-to-side) based on the size of the paper. Based on the settings of SP1002
003, 004, this SP sets the amount of offset for the paper sizes.
This is a mechanical adjustment that is stored before execution. This adjustment is
done for paper wider than 400 mm (in the main scan direction) after the adjustments of
SP1002 003, 004 have been done.
001 Cassette 1: 230 mm
002 Cassette 1: 310 mm
003 Cassette 1: 400 mm
004 Cassette 2: 230 mm
005 Cassette 2: 310 mm
006 Cassette 2: 400 mm
1918 Drum Cleaning Time Adjustment
Low temperature can increase the amount of toner that adheres to the drum. This SP
lengthens the time between copies, allowing more free rotations of the drum past the
drum cleaning blade.
This setting takes effect while the machine is not in CPM down mode.
If the machine enters CPM down, mode then the time interval is determined by either
the CPM down mode or this SP setting, whichever is longer.
