While using the TAGs, you may be asked to perform some of the following procedures. Specific instructions for completing these procedures are included here, rather than repeated in the body of each TAG. Please read this information before following any TAG.
When directed to
1Turn off the printer.
2Wait at least 5 seconds.
3Turn the power back on.
Checking ContinuityWarning
Make sure the printer is turned off and the power disconnected. Failure to do so may result in personal injury, equipment damage, or both.
To perform a continuity check:
1Turn off the printer and disconnect the power cord.
2Set your meter to the lowest ohm setting.
3Interpret the results as follows:
•
•
An infinite reading indicates an open circuit.
A zero or specific reading indicates continuity.
4To check an open or short circuit to ground:
•
•
•
Turn off the printer and disconnect the power cord.
Locate the circuit in question. (Refer to Chapter 6, “Wiring Diagrams and Electrical Data” , for circuit locations.)
Check all connectors and wiring on each side for corrosion, foreign objects, bent pins, loose socket housings, and/or loose wires.
Warning
The printer is equipped with safety interlock switches on all of its covers. These switches disable parts of the printer when the covers are opened. These areas present the risk of electrical shock, burns, and injury from mechanical hazards.
