I get error message

From a quick search of the HP forums, this error message seems to be fairly common.

Resetting the system might fix your problem. Try this: Press and hold the OK, Cancel, Black, and Color buttons all at once. Then shut off the printer. Keep holding all the buttons down until shut off is complete. Others on the HP forum who experienced the same error message noted that running through this twice will force the machine to recalibrate.

This is the source link to the above information.

Hope this helps!
