Theory of Operation
Microswitches
Microswitches are used primarily as paper size sensors and cover interlocks.
They are in a normally open state, and close when actuated. A bank of
microswitches is used to detect paper size in the universal trays.
Microswitches also employ hooks or catches for retention in the bracket or
frame.
Thermistors
Thermistors have a known value of resistance whose value varies with
temperature. Used primarily in the Fuser for temperature sensing.
