Hi @glynis_3,

I'd like to help!

To better assist you - 

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, try single-cartridge mode-

The printer you own can work in single-cartridge mode, wherein the printer will be able to print with one cartridge in the printer.which will help us identify if its a cartridge issue or a printhead issue.

To try single-cartridge mode follow the below steps:

remove the black ink from the printer, leave the color in and try printing 
then remove the color ink and, insert the black  in and try printing 

Hope this helps! Keep me posted.
