Black catridge printing is not working

Hi Aravind,

Are you using a refill cartridge? It would be best to allign after installing the cartridges?

Since most cartridges today have electronic contacts on them, if you dirtied them before installing the cartridge, it is possible that this could affect the performance, you might want to take the cartridge out and clean the contacts with rubbing alcohol.

Also, the alignment of the print heads may need to be adjusted, my hp requires this to make sure the color and black line up properly, otherwise you get a blurry image.

Furthermore, if the problem is with the color cartridge and you are trying to print a page of black letters and the printer is set to use colors, it may try to print the black using all of the colors instead of using the black cartridge. So you may need to clean the color cartridge as well. Try looking at the printing properties and making sure black is selected when printing something that is only text and see if it does it correctly then.
Good Luck!
