I will explain you the cause for it.
It prints in yellow first and then override with black for better quality. This is the reason your color ink gets empty.
Have a great day!

Either the print head for black is faulty, or the wiring to the black print head on carriage are broken. Try also cleaning the metal sensor to the black cartridge inside the ink carriage.

SOURCE: HP C7280 BLACK INK WON'T PRINT
That printer doesn't have printheads that get replaced with the cartridges. Here's a page on HP's site that describes what to do if one of your colors doesn't work. Give it a try and let me know how it works. http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01078810&cc=us&lc=en&dlc=en&product=3204785

This is getting to be a very common problem that I've found almost constantly with the HP88 K/Y (Black/Yellow) printhead. The problem is that the Black ink is pigment ink and in certain environments this just clogs to the point that no amount of cleaning will actually resolve the clog and you have to replace the printhead. The only long term solution I've been able to find is to replace the black cartridge with a 3rd party dyebase ink cartridge and run this through a NEW printhead to replace the pigment ink in that. Dyebase ink does not have any of the same problems and will work perfectly. The only trade off is of course that you lose your warranty and there is a certain amount of ink "bleed" where the edges of black are more fuzzy from ink mixing while it's wet but this is fairly minimal and as the L7580 is only really a document printer (rather than a photo one) it shouldn't make a huge difference. I've used this approach to great effect both at home on an L7680, K5400 and K8600 plus on the same models in 3 different schools where this clogging issue occurred so it's tried and tested. Hope it helps.

Yes, the problem is either air or dry ink in the ink feed tubes. Go to our web site at: www.ccl-la.com Look on the printer repair page and click the HP link. We have a step by step guide to purging the ink feed tubes that should get you back going again. Use the guide for Non-fax function HP printers. If the ink is dry you may have to repeat the purge several times to get the lines clear enough to print. You will also need to have full ink cartridges when you do the reset. If you have any questions just use the email address below.
I hope this helps, If so please rate our solution.
