8.5.4 Paper Retaining Mechanism

iR2270 / iR2870 / iR3570 / iR4570
The holding plate of the machine's cassette is fixed in position at all times, and does not move up/down at time of
pickup, and must temporarily be released when paper is set between it and the manual feed pickup roller. It is linked
to the upper guide so that it opens when the user opens the guide; to prevent the user from placing paper without
opening the upper guide, the guide is equipped with a stopper plate.
1. When the upper guide is closed,
the holding plate is locked in place,
and the stopper plate prevents the user from placing paper.
2. When the upper guide is open,
the holding plate is freed,
and the stopper plate opens, permitting the user to place paper.
