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 “Problems and Solutions” on page 34 for more
information.
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 load/eject button and press the power button. Hold
down both buttons until the power light starts to flash. Then release
them.
The printer prints one page containing the printer’s ROM version, ink
counter code, character table number, and a nozzle check pattern. Only the
nozzle check pattern is shown below:
5. After it prints the page, turn off the printer. Remember to reconnect the
interface cable, and turn on the printer and your computer.
6. Compare the quality of the printed nozzle check pattern with the sample
above. In particular, look for missing segments in the lines, which may
indicate a misaligned print head or clogged ink nozzle.
