HP ENVY 4500 missing lines when printing

[GM771]

My HP ENVY 4500 is missing lines or part of lines when printing. See attached image of the diagnostic print. Any suggestion? I already tried the page alignment procedure and also cleaning the contacts on the cartridges. Thanks.See diagnostic print-out

If cleaning the ink cartridge printheads did not help replace the black cartridge.

I saw the issue with the previous cartridge, so i replace it with a new one (as it was almost over anyway), but the issue is still there. So it does not seems cartridge related?

Did you try resetting the 4500 by removing the power cable?

Sure, no change. 

I made some other tests, hope it can give some ideas:

- Pdf printing: i see the issue

- Tried to take a snapshot and copy/paste in Word, still see the issue

- Took a snapshot, pasted in MS Paint, printed the image: no issue.

- Printing web pages from Chrome seems working fine (just the link on the very top of the print-out looks slightly cut).

Might be a driver issue?

I am running Windows 10.

Thanks

Remove the black cartridge and touch the printhead to a paper towel, do you see a solid line of black ink.

Hi, i tried uninstalling and re-installing the drivers as well as installing HP Smart on Win10. It seems now it is working fine.

Thanks.
