Is there a self-test to check my product operation separate from the computer?

• You can print the self test using 16 inch wide single sheets or continuous paper. Follow these steps to perform a self test:
  1. Make sure paper is loaded and the printer is turned off.
  2. To run the test using the Draft font, turn on the printer while holding down the LF/FF button. To run the test using the printers near letter-quality fonts, hold down the Load/Eject button while you turn on the printer. Either self test can help you determine the source of your printing problem; however, the draft self test prints faster than the near letter-quality test. After a few seconds, the printer loads the paper automatically and begins printing the self test. A series of characters is printed. To temporarily stop the self test, press the Pause button. To resume the test, press Pause again.
  3. To end the self test, press the Pause button to stop printing. If paper remains in the printer, press the Load/Eject button to eject the printed page. Then turn off the printer. Do not turn off the printer while it is printing the self test. Always press the Pause button to stop printing and the Load/Eject button to eject the printed page before you turn off the printer.
