Defeating interlocks
Different tests can be used to isolate different types of issues. For component or noise isolation, you
can run the diagnostic test after removing the covers for a better view of the areas that are being tested.
To operate the product with the covers removed, the door-switch levers (SW1, callout 1) must be
depressed (this is the door-closed position) with a folded piece of paper.
WARNING! Be careful when performing product diagnostics to avoid the risk of injury. Only trained
service personnel should open and run the diagnostics with the covers removed or with the door switch
levers depressed. Never touch any of the power supplies when the product is turned on.
WARNING! If the front- or right-door switch levers are depressed, the laser/scanners can be activated
while a door is open.
