THE INTERLOCK CIRCUIT
This printer has an interlock circuit(s) to meet safety and
international requirements.
Print Module Access Panel AC Interlock Swith
The interlock switch circuit disables the power supply voltage when
the print module access panel is lifted. This eliminates any potential
shock hazard or inadvertent printer start-up while moving parts in
print area are accessible. The print module access panel must be in
place and both thumbscrews must be tightened securely for printer
operation. See Figure 3-2.

Top Cover Interlock Switch
On the 5180 (55 dBa) Cabinet Model, there is a top cover interlock
switch. It is located in the upper left corner of the door opening. See
Figure 3-2. When the door is opened, the beeper will sound, printing
will stop, and the display will show Cover Open. To use the printer
with the door open, pull the switch plunger up and press the Clear
key to clear the display.
Note
Removing the print module access panel with the power applied
will energize the interlock circuit. If this happens, the print
module access panel must be replaced, power must be turned off
for a period of 5 minutes before attempting to reapply power.
