Paper Path
The media supplied from the Paper Tray is transported through the printer as
shown in the illustrations below. Media fed from the manual feed slot enters the
media path at the Feed Idle Roller.
Paper Feeding
The feeding mechanism consists of the manual feeder, Paper Tray, Pick Up Roller,
Feed Rollers, and Holder Pad. The rollers and sensors in the paper feed path control
paper registration and guide the paper through the image transfer, image
development, image fusing, and exit assemblies.
