2. MECHANISM DESCRIPTION
2.1 General Mechanism
The High Capacity Second Paper Feeder feeds the paper into the printer by receiving the signal from
the printer, which drives the pulse motor inside the High Capacity Second Paper Feeder, and this motion
is transmitted to rotate the one-way clutch of the hopping frame assembly. The paper is delivered from
the hopper into the printer through the turning of the hopping roller and feed roller.
Once delivered into the printer, the paper is then controlled and fed through by pulse motor (registration)
of the printer.
2.2 Hopper Mechanism
The hopper automatically feeds the printer with the paper being set, single sheet at a time. When the
paper is loaded in the paper cassette, it is then transported by the pulse motor, carrying forward only a
single sheet caught by the brake shoe at a time.
