Had a paper jam, removed paper and printer printed all collors including the black.After 3-4 prints the black started fading until it was gone. Ink status showed good but replaced with new HP cartridge. No black. Ran thru cleaning of print head, printed driven. No black. Cleaned print head manually. No black. Ran print & scan Doctor 5.0. No black.Test page shows colors are good but still no black. ANY SUGGESTIONS WOULD HELP
The troubleshooting steps in the document here may help resolve black not printing on your Officejet 6500a printer. You mentioned you had done a cleaning cycle from the printer. There are actually three levels of cleaning available, after one cleaning repeat and it will do the more aggressive cleaning. You also mentioned manually cleaning the printhead. Did you soak the printhead as shown in steps six through eight of the document?
