Inkjet ink - when you figure the per Qt cost .... you could be drinking Dom P w/dinner and still have money left over ........ Inkjets are the biggest ripoff for not photo printing oh and now the cartridges have microchips that have an expiration date ...... per page cost is expensive - for daily B&W printing your better off with something like an HP 1100 ...... IMHO

if it is out of warranty throw it out and by a new one repair costs will be more than what you paid .... of course you could uninstall and try reinstalling the software and drivers 1st ......
could be defective cartridges ............ I got a free brand new HP 1610, Scanner, Copier, Photo Printer for the cost of a new set of ink cartridges and a Firmware update for the Printer - when the wife needs the new Pics of my daughter printed out I use the 1610 other my 2nd hand HP 5 laser jet does the daily chores -
and FYI the print heads are sometimes on the cartridge itself and get changed out with new cartridges:

I have often take out "Empty" cartridges in my old Photo 700 Epson, and put them right back in to print lots more pics or 100's more text doc's ....
