Running a Self Test
You can run a self test to determine whether the problem comes
from the printer itself or the computer.
◗ If the results are satisfactory, the problem lies in software
settings, the interface cable, or your computer.
◗ If the self test does not print correctly, you have a problem
with your printer. See the suggestions in this chapter for
possible solutions.
Follow these steps to run the test:
1. Make sure both the printer and computer are turned off.
2. Disconnect the interface cable from the printer.
3. Make sure paper is loaded in the feeder.
4. Press the
E load/eject button and hold it down while you
press the Ppower button. Continue to hold the buttons
until the Ppower light starts to flash.
The printer prints a nozzle check pattern (shown on
page 5-8) and samples of fonts and colors.
5. To end the test, turn off the printer.
Using Hex Dump Mode
You can use the printer’s hex dump mode to identify problems
if you know how to interpret hex code. Or, you can fax the hex
printout to a technical support representative. Follow these
steps to use hex dump mode:
1. Make sure the printer is turned off and has paper in the
feeder.
2. Open the cover.
