Head up switch/Pinch Roller Switch (micro switch)
The head up switch, attached at the left of the print head as viewed from the media outlet, detects
that the print head is ready to print (head is down). When the head lever is lowered, the head
down cam pushes up the print head, the micro switch is turned on and the print head prepares
to print.
The pinch roller switch, interlocking with the head up switch, detects the vertical movements of
the pinch roller. This micro switch is positioned at 90.6 mm to the right of the main frame.
When this switch is turned on (When the pinch roller is down), the pinch roller feeds the media
and the print head prints.
