Question about HP Officejet Pro L7580 All-In-One InkJet Printer
Replacing the print heads fixes any poor print quality you are experiencing. Typically people replace print heads when a certain color (most likely black) is printing very faint or streaky. Over time the nozzles in the print head can get clogged with dried up ink. Enough clogged nozzles will inhibit ink from being deposited on the page in certain areas.

But replacing the print heads DOESN'T resolve this problem with this printer. I've just done so on my own HP L7580 after following all the preliminary steps HP recommends. I finally replaced both printheads - to no avail: the same white streaks on everything and a big expense for nothing.
