Customer Power Source Service Check
Use an ECOS Electrical Safety Tester (P/N 6339695) in the United States or a similar safety tester in other countries.
NOTE: The ECOS tester will trip ground fault detector protected outlets. This is a good test of the ground fault detector. Reset
the outlet as needed.
Plug the ECOS meter into the customer’s outlet. Follow the instructions supplied with the meter to test for the following:
•
Wiring errors
•
Low voltage
•
Neutral to ground short
•
Ground path impedance
•
Neutral impedance
NOTE: The customer is responsible for correcting problems with the power source.
Each branch circuit must be grounded for safety and correct operation of the printer. This ground must be connected either to
the electrical service ground or to a suitable building ground. The printer power cable has a green or green/yellow insulated
grounding conductor. This is a ground line,
not a neutral line.
Power Cable
1. Make sure the power cable is not damaged.
2. Make sure the power plug is the correct type.
Power On / Off Verification
1. Make sure all covers are installed.
2. Plug the power cable into the customer’s power outlet.
3. Power on the printer and watch the LCD.
4. Verify that the power-on diagnostic tests and initialization routines are successful.
5. After successful initialization, the printer should cycle automatically to either the READY or NOT READY mode, depending
on which power on state was selected when the printer was configured.
6. Power off the printer. Verify that the LCD goes completely blank and all fans stop.
