# 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 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 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.
