Cover interlock switch Disconnect the cover interlock cable from the
controller card at J15.
With the printer turned off, verify continuity
between cable pin 1 and pin 2 with the door
closed and discontinuity with the door open.
Verify continuity between cable pin 1 and pin 3
with the door open and discontinuity with the
door closed.
Verify discontinuity between cable pins 2 and 3
whether the door is open or closed.
• If either fails, replace the cover interlock
switch.
• If both pass continuity, turn the printer on, and
measure +5 V dc on pin 2 at J15 on the
controller card.
• Verify pins 1 and 3 at J15 are ground.
• If voltage or ground is not present, see
“Controller card service check” on
page 2-82 for more information.
