This is what my HP Tool Kit says about all lights blinking: Press the resume button to get the error code Turn the printer off and then turn it back on. If the error message still occurs, you may have a hardware failure. Call the HP Customer Support Center. Click here for information on getting help from HP. When I pressed on Click Here, this is what came up: You have a printing problem that can't be diagnosed by this troubleshooting program. It seems to be related to the printer setup. Try the following before calling HP: Turn your computer and printer off and then on again. If the problem continues or is accompanied by several error messages on your screen, check the cable connection between the computer and printer, and then reinstall the software that came with the printer. If these suggestions don't work, call the HP Customer Support Center. Before calling, have your serial number and printer model handy, along with any other available information about your computer system. Click the button next to the support options you need.
