hp930c: need to change ink catridge at 20%?!

[mOrphine]

im using a hp 930c printer and the ink catridge light on the printer is flashing. when i opened up the printer, the yellow arrow indicator points to something wrong with the black ink cartridge. i tried reseating the catridge in the printer and its still flashing. so i ran the hp software and it tells me my black ink catridge is at 20%.

does that mean im suppose to throw it away and get a new one?

sorry if that sounded like an inane question, i thought i would be using the catridge till there's 0% left!

can someone gimme some advice pls? thanx

Well, I also have an HP 930, and it doesn't do that. The ink test I think just gives an approximation based on how many sheets you've put through, so you may really be dry.
