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" on page 116. 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.
