Reversing System
The duplexing driver PCA receives the duplex admission command
from the printer first. It turns on the Duplexer deflector drive solenoid
(SL1701), and the Duplexer deflector in the printer then starts to send
the paper into the Duplexer. Within a specified period of time after
receiving the command, the duplexing driver PCA also drives the
reversing motor (PM1701) in straight rotation, and the reversing
rollers 1, 2, and 3 in XX direction. Therefore, the paper is fed in XX
direction (shown in the figure below).
Figure 5-23 Duplexing Unit
Within a specified period of time after the trailing edge of the paper is
detected with the reversing unit paper sensor (PS1701), the duplex
driver PCA pauses the rotation of the reversing motor (PM1701). The
duplex driver PCA then switches the reversing motor (PM1701) to
reverse rotation.
As the paper is fed along the feed guide, it is fed through the reversing
roller 4 and the feed roller 1 of the Duplexer.
