Sensors and Interlock Switches
These are of several different types of sensors and interlock switches, but they have one thing
in common - they tell the printer’s control logic what’s happening and where, enabling it to
continue with the process or, if a malfunction occurs, to light the appropriate indicator light
and report a specific error condition on the host computer screen.
The figure below shows the relative locations of the sensors that track card and ribbon position
and movement.
