MECHANISM DESCRIPTION

2.1

General Mechanism

The Multi-Purpose Feeder feeds the envelopes and paper into the printer by receiving the signal from
the printer, which drives the pulse motor inside the Multi-Purpose Feeder, and this motion is transmitted
to rotate roller-A and B. The envelope or paper is delivered from the separator into the printer.
Once delivered into the printer, the envelope or 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 envelope or paper being set, one sheet at a time.
After the envelope or paper is set in the Multi-Purpose Feeder, the pulse motor moves the envelope or
paper and a single envelope or paper caught by the separator is fed into the printer.
