Chapter E Multi-Feeder
The sheet (or envelope) at the very bottom of the stack is fed into the printer, one at a time, when the Multi
Feeder receives the signal from the printer.
(1) First, the hopping motor rotates in the direction of arrow D. The planet gear F moves to the direction of
arrow G, and drives rollers A and B. The roller C is linked to pulley I which is on the same shaft as roller A,
and it also turns at the same time as roller A. The paper is fed for a predesignated distance until the
leading edge reaches roller C.
(2) Next, the hopping motor rotates in the direction of arrow E. The planet gear F moves to the direction of
arrow H, and drives idle gear J. The rotation of idle gear J is transmitted to the gears linked to it, and
drives pulley I on the same shaft as roller A, turning roller C to feed the paper into the printer, until it
reaches the registration roller of the printer. During this process, a one-way bearing is engaged at pulley I
so that the rotation of pulley I is not transmitted to roller A, preventing any feeding of papers by roller A.
