Overview

The components of the paper loading mechanism and the loading method are as follows.

Feeding Direction Configuration Power Source and Control

  • Cassette Assy
  • Lift-up mechanism
  • Pick-up Mechanism
  • Intermediate feeding mechanism*
  • Lift-up Motor
  • Lift-up Encoder/Lift-up Scale

ASF Motor
ASF Encoder/ASF Scale

*: Uses the Duplex Unit's Intermediate Roller for feeding. For the details, see Intermediate feeding mechanism.


The paper feed mechanism is composed of the PF Motor, PF Roller, EJ Roller, and Star Wheel Assy, etc. When performing automatic duplex printing, the paper printed on one side is pulled back into the printer by the PF Roller and EJ Roller, and then it is reversed and fed continuously in the Duplex Unit.

WF-C879Ra/WF-C879R optional cassettes can be added up to three cassettes.
The optional cassette has the 2nd lift-up mechanism and 2nd  ASF mechanism in it. When loading paper from the optional cassette, the 2nd lift-up mechanism and 2nd  ASF mechanism pick up paper and load it to the intermediate feeding mechanism.
