PAPER FEED UNIT
*1: Swivel roller
The paper feed direction and the Tray loading direction are
at right angles to each other. Consequently, if the feed
roller is fixed, it will touch the paper when the Tray is
removed, resulting in possible paper jamming. To prevent
this, the swivel roller (paper feed roller) is designed so that
it drops down and touches the paper only when paper feed
is taking place.
*3: Paper up-down base release operation
When the tray is being removed, the projection on the right
side of the tray strikes the paper up-down base release
lever, causing the paper lift-up gear to be disengaged by
the gear coupling lever. As a result, the up-down base falls
under its own weight.

*2: Paper lift-up
When the paper feed tray is installed, the paper lift-up plate
is moved by the tray motor, paper feed idler gear and the
paper lift-up gear, causing the paper in the tray to be fed
automatically to the paper feed position.

*4: Paper size detection
The side guide and rear guide of the upper tray move,
causing the paper size detection knob to move as well. As
a result, the switch on the detection board is turned ON/
OFF. In this way, paper size detection takes place auto-
matically.
