Overview - Rollers and Sensors
The right drawer contains the paper registration unit (items 1-16)
and the right half of the duplex paper path (items 17-21). The
paper registration unit does the following:
Double-feed detection
Skew correction (sub-scan direction)
Side-to-side correction (main scan direction)

Paper transport timing control is a new feature
When the paper reaches the transfer timing sensor, it may be slightly early or late, depending on
how much time was needed for paper registration.
When the transfer timing sensor detects the leading edge of the paper, the machine will adjust
the speed of the transfer timing motor:
¾ If the paper is late at the transfer timing sensor, the motor speeds up and the roller feeds
the paper faster.
¾ If paper is early at the transfer timing sensor, the motor slows down and the roller feeds the
paper slower.
