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. Inform the IBM Installation Planning Representative (IPR) of
any problems with the customer’s 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
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.
Print Interlock Service Check
1. Power on the printer.
2. Open the printer top cover.
3. Open the forms thickness lever. The LCD should display
“057 CLOSE PLATEN” and the audible alarm should sound if it is
enabled.
