    The on/off light on my HP Officejet Pro K550 blinks continuously. The printer does not print while this is going on, and the unit cannot be powered down unless the cord is disconnected or the powerstrip is turned off. When the printer is turned back on, it goes right into this mode again.

I'm printing labels on my printer. After each run, the printer prints out an hp advertisement page for buying supplies, etc. Almost like a test page. How can I delete this annoying and wasteful...


Try this:
But first print a configuration report.(contain IP address)
Configuration Report
Release GO after LED begins blinking.
Now:
Reset the factory default settings (cold reset)
Turning on the printer while pressing the GO and CANCEL JOB buttons restores the factory default settings.
1 Turn off the printer.
2 Press and hold the GO and CANCEL JOB buttons.
3 Turn the printer on and continue to press and hold the buttons until all three LEDs are blinking.
4 Release the buttons.

Hey, my dell all in one printer 810 will not power on at all. I have measured the traffo into the printer and it reads 30vDV so it has power but will not start


Hi
Disconnect the unit completely from the AC outlet for 5 or 10 minutes, then plug it back again.It will works.
Also I suspect it may be a loose power switch, or a problem with the power supply.
If it is a USB printer that derives power through the USB cable and not from a seperate power cable, then check the USB cable. That may be the source of the problem if the cable is bad.
