HP Officejet Pro 6978 will not print black

[helpme12341]

My HP Officejet Pro 6978 will not print in black ink. It was purchased in 2018 and is used seldom. I ran out of ink a month or two ago and have just now gotten new ink. I just replaced all of my cartridges with hp brand ink and have now wasted more than half my color ink on test pages. The black will not print at all. I have checked the drivers, updates, vented the cartridge, cleaned the printhead (several times), and utilized the HP Print and Scan Doctor. I do not know how to solve this problem.

@helpme12341 Help you is exactly what I intend to do, here's what I recommend you do:

Try the copier as a stand-alone device without a computer and check if that works in color,:If it doesn't work, this could be a hardware issue,

however, if the copier works and yet, the print out from the computer doesn't work in color, you can try the below steps:

• Press "Windows key" + "r" to get the "Run" window.
• Type "services.msc" to get Services - Go to "Print spooler" - Right-click and "Stop" the service.
• Now again open "Run" - Type "spool" and ok - Go to PRINTERS folder - delete everything in that folder.
• Go to services again - Start the print spooler.
• Now check for issue resolution.
• If the issue persists, also try clean installing the printer drivers. Here are the steps:
• First, unplug the USB cable from the printer if present. 
• Go to Control panel - Programs and feature - Select all the HP printer entries and uninstall them.
• Now go to Control panel - Devices and printer - Select all the printer entries and remove the device.
• Press the "windows key" + "r" to get the "Run" window open - Type "printui.exe /s" (There is a space between .exe & /) and press enter.
• Under print server properties, go to drivers - remove any entry there as well.
• Again, go to the Run window, type - "c:/programdata" - Go to the Hewlett Packard folder, remove any printer related folders & files.
• Restart your computer.
