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 page 94.) If the self test works properly the problem is probably caused by the computer, the application software, or the interface cable. If the self test does not work, see “Where To Get Help” on page 96.
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.
