HP color laserjet 2550 series Manuale Di Servizio

If your document is printing but the quality is not what you expected, start by using the print-
quality 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 (

).

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 

.

●

If the problem is affecting only pages that are printed in color, see 

.

The following examples depict letter-size paper that has passed through the printer short-
edge first. These examples illustrate problems that would affect all pages you print, whether
you print in color or in black only. The topics that follow list the typical cause and solution for
each of these examples.
