Platen Open/Paper Out Switches - Printronix P9012 Maintenance Manual

Platen Open/Paper Out Switches

These switches signal the mechanism driver that the printer is out of paper or
the platen has been left open. When either signal is detected, paper transport
is disabled and the ribbon loses tension. The signal faults are reported to the
control panel from the MCU to the DCU.
