Chapter 8
The cassette detection switch (SW2) detects the presence/absence of the cassette.
The manual feed paper sensor (SR707) and the cassette paper sensor (SR709) detect the presence/absence of the paper in the manual feed tray and the cassette.
The reverse sensor (SR706), pre-registration sensor (SR708), registration sensor (SR710), paper loop sensor (SR6001), and fixing delivery sensor (SR6005) detect
the arrival and passage of the paper on the feed path.
The delivery paper full-level sensor (SR713) and delivery sensor (SR715) detect the condition of the delivery outlet.
The machine also has the paper displacement sensor (SR714).
When reverse operation is performed to feed paper for printing of the second page during duplexing printing, the machine controls the duplexing solenoid (SL5017)
and uses the registration sensor (SR710).
