 my printer is printing blurry text with missing letters. The smaller the font/ more words on page the bigger the mess is. My printer is our of warranty so no support available from HP. I have checked the ink levels on smart app and they are fine. I have manually cleaned the cartridge and the photo above is the result after that. Any suggestions?

Hi @TadhgMacD

 

 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 devices?  

 

You may also refer to this document with steps to fix " 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 

 

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.
