3.5 Paper Feed

3.5.1 Outline of the paper feed

1) Paper feed mechanism
The paper feed mechanism supplies paper from the built-in cut-sheet feeder.
The built-in cut sheet feeder is driven by the paper feed motor. Paper stacked in the
sheet feeder is picked up and fed automatically. Even thick paper like envelopes can
be fed automatically without selecting the paper type mechanically with the paper
selection lever.
When the paper is sensed by the paper end sensor, it is fed automatically by the
paper feed roller until it reaches the starting position for printing on the platen.
During printing, the paper is fed by the rotation of the paper feed roller.
The paper, after printing, is delivered by the eject roller.
2) Paper feed operation
It is not possible to perform paper feed operations with the printer, however, paper
ejection can be performed with the RESUME button.
