Hi all;
Sorry for the number of posts lately. I am trying to work my way
through F9 fixing and tweaking all the little issues that have been
around on my machine for the last 2 - 3 Fedora versions. I am almost
finished.
I recently had my HP #74 refilled rather than purchasing a new one. It
works fine but hp-toolbox (and the WindowsXP gui thingie) continues to
tell me that the black cartridge is still very low.
Does HP have some secret little way of telling I am using a refill and
therefore refuses to acknowledge it?
Yes, they do. The circuitry to detect low levels is on the cartridge itself
and it locks at the lowest reading. A long time ago a friend of mine found
some software on the net to reset Epson cartridges. You may have to go
looking for the same magic for HP.
Yeah - I try not to use any printers with chips on the cartridges if I
can help it. I have a Canon Pixma that has a prism in the bottom of
the cartridge that is used to determine the ink level. I vote it
'Best Ink Level Monitor Ever, since it actually reports the level of
ink.
Carts with chips just count the number of print passes - they have no
way of sensing the actual ink level...
There may be a hardware reset like this:

But you will need to google around for your particular model of cartridge...
Good Luck!
