9.1.8 Controlling the Fixing Inlet Sensor Drive

The machine is equipped with a fixing inlet sensor to prevent paper from remaining inside the fixing as-
sembly. The output of the sensor is used to move a lift mechanism, thereby making sure paper movement
will not be disrupted.

<Paper Detection>
If paper is detected while the fixing inlet sensor is
moving up, the machine will indicate the presence
of a fixing inlet residual paper jam.
Reference:
Sheets of paper detected by the fixing inlet sensor must be B5 or larger.
ERROR CODE:
