NO PAPER SENSOR
If paper runs out in the Paper Cassette, the ACTUATOR (SUPPORT ASSEMBLY) lowers
and the flag of the ACTUATOR (SUPPORT ASSEMBLY) that has stayed in the NO PAPER
SENSOR sensing area leaves there. Thus, the light of the sensor is transmitted. When the
sensing area is blocked (paper is present), the signal becomes OFF.
LEVEL SENSOR
This sensor detects, by the ACTUATOR position, whether paper in the Paper Cassette is
lifted. When the flag of the ACTUATOR leaves the LEVEL SENSOR sensing area, the sen-
sor detects that the paper has been lifted.
PRE FEED SENSOR
This sensor detects a paper jam in the Paper Cassette by the paper position and sensor ON/
OFF time.
The sensor ON/OFF states can be monitored by paper passing through the PRE FEED
SENSOR sensing area.
