Cover Open
Switch
Be sure the cover open switch is properly installed
in the left print unit guide. If you still have a problem,
remove the interconnect board and check the con-
nection of the cover open switch cable (CNCOV2).
If it is correct, test the continuity of the switch. The
switch circuit is normally closed. When the switch is
pressed, the circuit opens.
