2.1 General Mechanicsm
The sheet at the very top of the stack in the paper cassette is fed into the printer, one at a time,
when the High Capacity Second Paper Feeder receives the signal from the printer.
(1) First, the hopping motor rotates in the direction of arrow A. The hopping gear is turned, by the
idle gear, and roller C on the same shaft is turned. At the same time, planet gear D moves in the
direction of the arrow E, and roller G turns; the paper is fed for a predesignated distance until its
leading edge reaches roller G.
(2) Next, the hopping motor rotates in the direction of arrow B while the hopping gear also turns.
Because of the one-way bearing being engaged at the hopping gear, roller C does not turn. The
planet gear D moves in the direction of the arrow F, drives the Roller G and feeds the paper into
the printer, until it reaches the registration roller of the printer.
Once the delivered into the printer, the paper is then controlled and fed through by registration motor of
the printer.
