HP6950 won't print black,

[mspat1]

Device will not print black.  Will print colors, but not black.  Cartridges all brand new and full.  Spent sevveral hours already and help advice does not match what I find in Windows 10.  Have tried all the troubleshooting and nothing resolves the problem

@mspat1, Welcome to the HP Support Community!

I understand the printer is not printing in black. Let us try these steps:

Make sure the plastic tape if any is removed from the new ink cartridge before placing it in the printer.

Try making a standalone copy in black and check if that works. By this, we can conclude if this is a hardware or a driver issue.

Clean the printhead up to 2 times and print a quality report to check the result as shown in this document - Black or Color Ink Not Printing, Other Print Quality Issues
