HP inkjet 940XL
Microsoft Windows 7 (64-bit)

Fairly new genuine HP black cartridge installed.  Faded black ink in parts of top half of page, worst near top.  Doesn't happen with every page, about 40% though.  Have printed test sheet, cleaned and aligned print heads - no improvement.

Alright, first make sure the printer is plugged directly into a wall outlet and not a surge protector. Once done, this document should assist you with troubleshooting print quality issues with your printer.

 

If after following the above you are still having issues, the printer needs to be replaced. You can contact HP Support by clicking on this link and filling out the form at the bottom to see what options are available.

Hey @KingstonJustice,

 

Welcome to the HP Support Forums.

 

I see that you are having some issues with print quality. I can help you with that, however I am going to need to know the name of the printer as it appears on the front label. Once I know that I will be better able to assist you.

Thanks. Printer now working ok.  Info:  I started working through the troubleshooting link & print quality diagnostic page looked fine, as it did before.  I decided to check the ink tubes anyway but they look fine.  After I shut the top, the printer began to calibrate the linefeed without my requesting it.  I don’t think I’d tried that before anyway so I let it carry on. I didn’t use the printer again until Tuesday and it was fine: 9 pages all ok.  Today I used it again and it’s still ok so I assume the problem is resolved although I’ve not yet done a lot of printing.  Your troubleshooting page is good.
