I want to eliminate the "ink cartridge missing or damaged" error from
all-in-one. I'm exploring three options, and option three is to use a
magic key combination on the printer's own keyboard.
Google has a cached page at
that mentions a magic key combination on a Photosmart printer that
the printer and resolves a bogus printer error. Does anybody know of
similar key combination for the HP Officejet L7500/7600/7700 series?
