6.11.3 DUPLEXER COVER SWITCH
The Duplex Unit cover open switch [1] is a microswitch.
This switch detects if the cover is open or closed.
When the cover is closed the switch is closed. The circuit is closed at the 4 terminal pins [2]
that connect to the DIB. The printer controls the Duplex Unit through the DIB.
The switch breaks the connection between the printer and Duplex Unit when the cover is
open.
