HP Office Jet Pro 6960 Wont print yellow or magenta
Operating System: Microsoft Windows 10 (64-bit)
HP Office Jet Pro 6960 will not print yellow or magenta. I have cleared print heads, I have run all diagnostics, I have run HP print and scan doctor. No error messages, no problems identified - but still no yellow or magenta on any prints.
Is my printer broken? On the black and cyan cartridges printing is perfect, monochrome is sharp no missing area etc.
