Resolving problems that did not generate messages
If the printer is not responding properly, complete the steps in the following checklist, in
order. If the printer does not pass a step, follow the corresponding troubleshooting
suggestions. If a step resolves the problem, you can stop without performing the rest of the
steps on the checklist.
Troubleshooting checklist
1. Make sure the printer Ready light is on. If no lights are on, complete these steps:
a. Check the power cable connections.
b. Check that the power switch is on.
c. Check the power source by plugging the printer directly into the wall or into a
different outlet.
d. If none of these measures restores power, contact HP Customer Care. (See HP
customer care or the support flyer that came in the printer box.)
2. Check the cabling.
a. Check the cable connection between the printer and the computer or network port.
Make sure that the connection is secure.
b. Make sure that the cable itself is not faulty by using a different cable, if possible.
c. Check the network connection. See Checking the network .
3. Ensure that the print media you are using meets specifications. See Print-media
specifications .
4. Press (
G
O
) and ( C
ANCEL
J

) simultaneously to print a Configuration page and a
Supplies Status page. If the printer is network-enabled, an HP Jetdirect page also prints.
a. If the pages do not print, check that at least one tray contains print media.
b. If the page jams in the printer, go to Clearing jams .
5. If the Configuration and Supplies Status pages print, check the following items.
a. If the pages print correctly, then the printer hardware is working. The problem is with
the computer you are using, with the printer driver, or with the program.
b. If the pages do not print correctly, calibrate the printer. See Calibrating the printer .
Print the pages again. If the pages still do not print correctly, the problem is with the
printer hardware. Contact HP Customer Care. (See
HP customer care or the support
flyer that came in the printer box.)
6. At the computer, check the print queue or print spooler (Print Monitor or Print Center
Queue for Mac OSs) to see if the printer is paused or set to print offline.
7. Verify that you have installed the HP color LaserJet 2550 series printer driver. Check the
program to make sure that you are using an HP color LaserJet 2550 series printer driver.
8. Print a page from the HP Toolbox.
a. If it prints, then the problem is with the printer driver. For Windows, try using the
other printer driver. Or, for Windows or Macintosh, uninstall the printer driver (see
Uninstalling the printing software ) and reinstall it (see the getting started guide).
b. If the page does not print, then the problem is with the computer or the program.
