Network problems
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 Printing a Self Test. If the self test works properly the
problem probably lies in the computer, the application software, or the interface cable. If the self test does not work, contact
your dealer or a 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.
Cause What to do
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.
The power switch is not in the ON position. Check the status of the power switch. When Power off timer is
enabled, the printer turns off even if the power switch is in
the ON position. See Default Setting mode.
The lights come on briefly and then go off. The lights stay off even when the power is turned on again.
Cause What to do
The voltage ratings of the printer and electrical
outlet may not match.
Check that the printer’s voltage rating matches the voltage of
your electrical outlet. If the voltages do not match, unplug the
printer and contact your dealer immediately. Do not reconnect
the power cord to an electrical outlet.
