PAPER WINDING DETECTION CONTROL
With the roller fusing type Fusing Unit, paper jam may cause the paper to wind
itself to the Fusing Roller. This Winding Detection control monitors the paper
to detect when it winds itself to the roller lightly so that it can be removed
easily.
Operations are explained below.
It detects the winding before the roller is completely covered. (The length
of the paper wound to the roller is shorter than the circumference of the
roller.) The back-edge of the paper is sticking out from under the Fusing
Unit and can be removed.
When the paper jam occurs, rotating the Fusing Motor (M4) will make the
paper stuck to the Fusing Roller even worse, so the unit will stop
immediately.
