Preliminary Checks
Before troubleshooting the printer, verify that each of the following conditions are met:

Verify that the wall socket supplies clean AC current that matches the voltage rating on the printer. Measure the
voltage at the wall socket.
2.
The POWER CORD must be free from physical damage, short circuit, wire breaks, or miswiring.
3.
The printer must be grounded properly.
4.
The printer should not be located in a place where volatile or inflammable gases are produced.

8.
If you cannot print data from the host computer, initiate the printer’s self test and check for problems with the
output. Check the Default Settings printed on the Self Test for any incorrect settings.
