Most printer problems have simple solutions.
You can check the operation of your printer using the self test.
See “Running the Self Test” in Chapter 1. If the self test works
properly, the problem probably lies in the computer, software,
or interface cable. If the self test does not work, contact your
dealer or qualified service person for assistance.
Note:
If you are an experienced user or a programmer, you can print a
hexadecimal dump to isolate communication problems between the
printer and computer. To print a hex dump, turn off the printer.
Next, hold down the
LF/FF
and
Load/Eject
buttons while you turn
on the printer. Then send data from your computer. The printer
prints all the codes it receives in hexadecimal format.
Power Supply
This section describes solutions for problems related to the
power supply.
Power is not being supplied
The lights on the control panel do not go on.
Check that the power cord is properly plugged into the
electrical outlet.
If the electrical outlet is controlled by an outside switch or
automatic timer, use a different outlet.
Plug another electrical device, such as a lamp, into the outlet to
determine whether the outlet is operating properly.
