3.2.2.4 Paper 

eject 

After the printing image on the exposure 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 heat roller and the pressure roller in the  
fixing unit.  The paper eject actuator detects whether the paper is ejected correctly or not. 

After the paper exits from the heat roller, the paper is turned by the rear cover and ejected face 
down into the top output tray through the eject roller ASSY.
