The HP officejet 7140xi scanner worked fine before the "scanner failure" message appears. If I turn it off and back on again the message goes away, but appears in a short time without using the scanner or the printer. I have gone thru all the HP recommended steps of shutting off the power and turning it on with either the # and 3 or # and 6 key depressed . Nothing has worked . I am ready to trash this system Richard

help window says "supply expired. printing stopped. replace black ink cartridge." but I just replaced it, and when I use the menus to check ink levels it says black ink is at 90 percent. (not 100, even though it's a new cartridge)
