HP toner 902XL on HP OfficeJet Pro 6975

[WPC1]

My printer is HP OfficeJet Pro 6975. Recently I bought HP 902XL toner from Amazon Prime. Recently I changed out the black toner with the 902XL. It worked well for a week or 2. (I printed about 20 pages of documents) I don’t why the black ink is not working now.

Hi @WPC1,

Welcome to the HP Support Community

 I'd like to help!

I understand you are unable to print in black.

To assist better-

1) Does the copy print out the same way? 

2) What's the application you are trying to print from? Have you tried printing from a different application or device? 

While you respond to that, let's print a Print Quality Diagnostic page -

1. Load plain white paper in the input tray.

2. From the printer control panel, open the Setup  menu.

3. Open the Reports or Tools menu.

4. Touch Print Quality Report.

Post the Print Quality Diagnostic page here so we can help you further. 

You may also refer to this document with steps to fix the " Print Quality Issues" issue applicable for your printer -  Print Quality Issues

 Also, try updating the printer's firmware - HP Printers - Updating or Upgrading Printer Firmware 

Hope this helps! Keep me posted.
