Phaser 4500/4510 Service Manual 2-33
Theory of Operation
Printer Options
Three options are available for the Phaser 4500/4510 printer:
■ Duplex unit
■ Stacker
■ 550-sheet feeder
Paper transport information for the options is discussed earlier in this chapter.
Duplex Unit
The duplex unit used on the Phaser 4510 differs from the one used on the
Phaser 4500. While the two units function exactly the same, they use different
motors due to the difference in speed, and they are shaped differently due to
the change in the location of the cooling fan.
Drive Transmission Path
The rotating force of the duplex unit motor is transmitted by various gears to
components requiring mechanical drive as shown in this flow chart and the
gear layout that follows.
