I have the latest drivers and firmware installed, both the print heads and ink are official HP products and we are using Photoshop CS6 on Windows 10 Pro x64. We have tried both calibrating colour's and realigning the print heads, manually cleaning the print heads as well as running the diagnostic Test built into the printer.
From what we can tell the diagnostic test shows/tells us all colours are fine. However when we print we keep getting random red bands through the image regardless if its a black and white or colour print, does anybody have any idea as to what could be causing this?
I didn't find the right solution from the internet.
