IV. OPERATION OVERVIEW
A.

Overview

Figure 10-401 is the concept figure of the structure of the cassette feeder.
The cassette feeder's operation is controlled by the feeder controller PCB. The main
unit's DC controller PCB sends the pick-up control signal to the feeder controller PCB.
When the feeder controller PCB receives the pick-up control signal, the feeder motor
(M651) begins to rotate, and the pick-up solenoid is turned ON. Once the paper has
passed through the separation roller in order for any double feeds to be extracted, the
paper is fed through the feed roller and the vertical path roller on its way to the main
unit.
Further, the mechanical pick-up mechanism and the paper size selector mechanism
of the cassette feeder perform in the same way as those of the main unit.
The unit depicted above is fitted with an ADF. The construction of the main unit is
also the same for units not equipped with an ADF.
