1.1 Functions of the Paper Feed Unit

This printer supports 2 paper feeding methods: automatic feeding from the Auto Sheet
Feeder (ASF) and manual feeding from the manual paper-feed slot. The ASF, driven by
the paper feed motor, feeds paper automatically.
Manual feeding takes precedence over automatic feeding; you can feed paper manually
even when paper is set in the ASF.
When paper is detected by the photo-interrupter type paper end sensor, it is fed to the
print start position on the platen via the paper feed rollers.
Although paper has been fed by the pick-up roller, if it cannot be detected by the paper
end sensor, an auxiliary function of this printer reattempts feeding. If the paper still
cannot be detected, a paper feed error will occur.
