Fuser Assembly
The press roller presses the paper with toner against the heated
fuser roller which fuses and fixes the toner to the paper. The
separator pawl separates the paper from the fuser roller.
Exit Unit
The fused paper is ejected from the printer.
The exit sensor checks the state of the paper, while the flap
performs the change-over of paper exit direction (face down, face
up).
As the paper leaves the fuser it pushes down the exit link which
turns on the exit sensor on the printer controller. The printer
controller detects a paper jam if the exit sensor is not turned on
within the prescribed time or when it continues to be turned on past
the prescribed time.
Face down/face up switching for paper exit is performed by switching
the flap lever (manual) or by command from the interface controller
(automatic).
