1.1 About the Paper Feed Section

1.1.1 Paper feed functions

In this printer, sheets are supplied automatically from the auto sheet feeder.
The auto sheet feeder is driven by the paper feed motor, and paper stacked in the
sheet feeder is picked up and fed automatically. Even envelopes can be fed
automatically without requiring that the paper type be selected with a mechanical
paper selection lever, etc.
When the paper is sensed by the photo interrupter type paper end sensor, it is fed
automatically by the paper feed roller until it reaches the print start position on the
platen.
During printing, the paper is fed by the rotation of the paper feed roller.
After printing, the paper is delivered by the eject roller.
