Printquality checklist

Use the following checklist to solve general print-quality problems:

1. Check the printer driver to make sure that you are using the best available print-quality option, or return to the default settings. See the HP Color LaserJet 2550 Series Printer User Guide for more information about print-quality options.

2. Make sure that the paper or print media you are using meets specifications. See the HP Color LaserJet 2550 Series Printer User Guide for more information. Generally, smoother paper provides better results.

3. If you are using a special print media such as labels, transparencies, or letterhead, make sure that you selected the correct media type (see the Paper tab in the printer driver). See the HP Color LaserJet 2550 Series Printer User Guide for information about

HP print-media specifications. Also see the HP LaserJet Printer Family Print Media Guide (http://www.hp.com/support/ljpaperguide).

4. Print a Configuration page and Supplies Status page at the printer by pressing © (Go)

and © (Cancel Job) simultaneously. If the pages do not print, then the problem is in the hardware rather than in the software.

• Check printer status messages on the Configuration page.

• Check the Supplies Status page to see if any supplies are low or empty. Note that no information is provided for non-HP print cartridges. Replace non-HP print cartridges with HP print cartridges.

5. Use the HP LaserJet Toolbox to print a Demo page. If the page prints correctly, there might be a problem with the printing software. Uninstall the printing software and then reinstall it (see the HP Color LaserJet 2550 Series Printer Getting Started Guide).

6. Try printing from one of the other printer drivers. For example, if you are using the PCL 6 printer driver, print from the PS printer driver.

7. Try printing from a different program. If the page prints correctly, the problem might be in the program from which you were printing.

8. Restart the computer and the printer and try printing again. If the problem is not resolved, choose one of these options:

• If the problem is affecting all printed pages, see Solving image-quality problems (all print jobs).

• If the problem is affecting only pages that are printed in color, see Solving image-quality problems (color print jobs).
