Hi, I just bought a new inks for my printer, both black and colour, and installed them immediately. I also printed a test page and alligned the cassettes and everything seemed just fine. However when I wanted to print a PDF document I downloaded from the internet, text had a "shadow" behind it (basically the black colour is moved up and on its place, there's a gray equivalent of the text). So I tried restarting the printer, printing some test pages, even reinstalled the cassettes and the printer, but the issue still remains. As I said, I tried a few sollutions that are here in forum, but unfortunately it didn't help me at all. Thank you for any help

 

UPDATE: I tried giving the printer some rest over night and printed the same PDF I wanted to print yesterday. Majority of the text was printed correctly, but few letters and QR code and barcode on the page were with the same shadow as you can see on the photo

closer look at the text with noticable shadowcloser look at the text with noticable shadowoverall look at the test page from HP doctor softwareoverall look at the test page from HP doctor software
