Paper Transport
D372 24 SM
When the positioning roller is raised:
The motor switches on again, raises the positioning roller arm, slows down slightly, and
then the arm stops at the home position.
The motor slows down slightly before reaching the home position to reduce the impact
and noise of the arm returning to the home position.
This cycle of lowering the positioning roller, touching the paper with the positioning roller
and return rollers, and then lifting them again and stopping at the home position, is done for
each sheet of paper.
Transport Motor Control
The transport motor drives all the rollers inside the finisher and controls the line speed of
the finisher.
The transport motor accelerates to match the line speed of the main machine (150
mm/s).
The transport motor speed accelerates to 600 mm/s after the leading edge of the
sheet passes the entrance sensor and feeds 21.5 mm.
After the trailing edge goes 96 mm past the entrance sensor, the transport motor
slows the line speed to 200 mm/s for paper shorter than 300 mm, or to 300 mm/s for
paper longer than 300 mm.
After the paper sensor detects that the trailing has fed 45 mm past the exit roller, the
transport motor slows the line speed to 200 mm/s so that the sheet can be
positioned for jogging. At this time, the positioning roller arm motor switches on and
starts to lower the positioning roller arm and positioning roller.
The transport motor slows the line speed in the finisher to match the line speed of
the paper path in the main machine. The positioning roller reaches the end of its
downward stroke and remains in that position long enough to feed the sheet back
against the bottom fences. The positioning roller arm motor reverses and raises the
