NOTE: 1) The machine uses a friction pad [F] and feed roller system. ( :
Handling Paper – Paper Feed – Paper Feed Methods – Friction Pad)
2) When the rollers stop and paper is fed by the registration rollers, the
one-way clutches in the pick-up and feed rollers ensure that these
rollers do not resist paper feed.
3) The guides [G] help to feed paper that is not perfectly flat.
4) Paper feed start timing depends on the selected printing speed: see the
Timing Charts.
