HP OfficeJet Pro 6978 not printing after cartridge replacement

[Jsawch99]

After replacing the black ink cartridge with a brand new one the printer now refuses to print anything. All test pages come out blank. I get two little black dots at the top of the page at best. It was printing fine with the old cartridge, however that cartridge is out of ink. 

I'm printing in Black and White and get nothing whenever I try to print. I've already tried cleaning the print head via the touch screen menu. I've also checked the cartridge vent. Neither one of these resolved the issue. 

I just want it to print again.

@Jsawch99, Welcome to the HP Support Community!

I understand the printer is printing blank pages. Are you using HP ink cartridges?

Make sure you have tried the steps mentioned in this document - Black or Color Ink Not Printing, Other Print Quality Issues

Clean the printhead up to 2 times and print a quality report to check the result.

Try printing in color to check if the color ink cartridges are working fine.

If the issue persists with the new black ink cartridge, I'm afraid it could be defective. Please reach out to the HP Technical Support team in your region regarding the replacement options. 

You may create a case on the website to obtain a case number if required. Kindly watch this video to know how.
