Problems and Solutions
Most problems you may encounter while operating your printer
have simple solutions.
You can check the operation of your printer using the self test. See
“Running the Self Test” on page 1-11. If the self test works
properly the problem probably lies in the computer, the software,
or the 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
Load/Eject
and
LF/FF
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
Power is not being supplied
The lights on the control panel do not go on.
The power cord may be unplugged. Check that the power cord is
properly plugged into the electrical outlet.
The outlet may not be operating. 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.
