Duplex unit pick-up operation
After the side registration adjustment is completed, the duplex driver sends the refed paper presence
status to the printer. Once the status is reviewed by the printer, it sends the duplex unit pick-up
command to the duplex driver.
The duplex driver activates the duplex feed motor (M3101) and feeds the paper. When the paper is
detected by the registration paper sensor (PS2), the duplex driver deactivates M3101, stopping the
paper feed process. The duplex driver then activates M3101 to resume feeding once it receives the
refeed command. Once the media is in position, the duplex driver will deactivate M3101 and stop the
duplex feed roller. After the second side of paper is printed, the paper is fed to the face-down delivery
bin.
