Theory of Operation
Sensors
The printer contains a number of sensors of various types that perform a
variety of functions. One group of sensors track the progress of the paper
along the paper path, and detect if a paper jam occurs. Other sensors detect
the presence of the print cartridge, stop printer activity if a door is open, and
monitor the fusing temperature. The basic printer has 18 sensors, while a
fully-optioned printer has 30 sensors.
The types of sensors in use vary with their function. In general, there are four
basic type in use:
■ Photo
■ Microswitch
■ Soft Touch Sensors (STS)
■ Magnetic
Most of the photo sensors consist of a LED in one arm of a U-shaped holder,
and a photo-transistor in the other arm. When nothing is between the arms of
the sensor, light from the LED falls on the photo-receptor, turning it on. If the
light is interrupted, the photo-transistor turns off. The on- or off-state of the
transistor is used as a signal.
The microswitches are used primarily as interlocks in the printer. They are in a
normally open state, and close when actuated. A bank of switches in a holder
is used for detecting the size of paper in use in a tray. Cams in the tray close
the switches in various combinations (see “Control of Paper Size” on
page 2-17) to send a size signal to the controller.
The Soft Touch Sensor has a known value of resistance whose sensitivity
varies with temperature.
The magnetic sensor detects the magnetic properties of the toner in the print
cartridge.
A fifth sensor in use in the printer is the antenna used to communicate with
the CRUM in the print cartridge.
The list of Sensors and interlocks that follows gives each sensor by its name,
lists which of the types it is, and briefly describes its function in the printer.
The reference column lists manual pages where illustrations show the
location of the sensor.
