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) to turn the reversing rollers 1, 2, and 3 in the direction shown in figure 31.

Figure 31.

Duplexer

 

Within a specified period of time after the trailing edge of the paper is detected with the reversing

 

unit paper sensor (PS1701), the duplexing driver PCA pauses the rotation of the reversing motor

 

(PM1701). The duplexing driver PCA then switches the reversing motor (PM1701) to reverse

 

rotation.

 

As the the leading edge of the paper is fed into the feed guide, it is fed through the reversing

 

roller 4 and the feed roller 1 of the duplexer.
