Status monitoring
This function includes detection of static media jams, interlocking, and insertion of the HCF media tray
assembly.
Static media jam detection
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 startup procedure and at
every jam/fail detection. The status of all relevant sensors are checked during the startup procedure. In addition,
the sensor states are always checked at every constant time for the jam/fail detection in order to monitor the
variation in sensor levels.
Interlock detection
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.
When “open”, the switch (top door interlock) is detected, printing operation is inhibited, and the 24 V supply to
the media feed lift motor and the transport motor is shut off. When “open”, the switch (HCF unit docking
interlock) is detected, and transfer of media from the HCF is inhibited.
