The sensor turns on (light receiving) upon detecting media, and determines that media is present.
Status monitoring
This function includes detection of static media jams, interlocking, and insertion of the HCF media tray
assembly.
Static media jam detection
This function checks the status of all relevant sensors on the media path to detect media jams. When media is
present on the sensor, it is treated as a static jam. This detection of media jam is carried out during the start-up
procedure and at every jam/fail detection. The status of all relevant sensors are checked during the start-up
procedure. In addition, the sensor states are checked constantly for the jam/fail detection in order to monitor the
variation in sensor levels.
Interlock detection
This function checks the open state of the switch (top door interlock) and the switch (HCF unit docking interlock).
This detection is constant while the power is on.
