Running a Printer Check

You can run a printer check to determine whether the problem
comes from the printer itself or some other source.
If the results are satisfactory, the problem lies in software
settings, the interface cable, or your computer.
If the printer check does not print correctly, there is a problem
with your printer. See the suggestions in this chapter for
possible solutions.
Follow these steps to check the printer:
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 printer.
4 Hold down the E load/eject button and press the Ppower
button. Hold down the buttons until the Ppower light starts to
flash. Then release both buttons.
The printer prints one page containing the printer's ROM
version, ink counter code, and a nozzle check pattern. Only the
nozzle check pattern is shown below:
