CHAPTER 3 THEORY OF OPERATION

2.2.3 Paper eject
After the printing image on the photosensitive drum is transferred onto the paper, the paper is
fed to the fixing unit to fix unfixed toner onto the paper.
Afterwards, the paper is ejected from the fixing unit by the first eject roller in the fixing unit.
The eject sensor lever detects whether the paper is ejected correctly or not. And Eject actuator
2 protects from accordion jam in the fixing unit when the tip of the paper doesn’t eject from the
unit.
After the paper exits from the first eject roller, the paper is turned by the rear cover and ejected
face down into the top output tray through the second eject roller. If the rear cover is open, the
paper is ejected face up straight to the printer rear (straight paper path).
