Phaser 4500/4510 Service Manual
The functions of the main components of the Phaser 4500/4510 printer are
described in the following sections:
Paper tray
Paper feeder
Print cartridge
Transfer roller assembly
Laser assembly
Fuser
500-sheet paper exit
Drive
Electrical
Paper trays include the 150-sheet and 550-sheet trays. Since they are
functionally equivalent, only the 150-sheet tray is described here.
The trays adjust to accept various paper sizes. The end and side guides
adjust to match paper sizes shorter than A4, or narrower than Letter. To
accept paper longer than A4, the tray extension must be unlocked and pulled
out, and the end and side guides adjusted to match the size.
