I have a HP laser printer pro MFP M477 fnw, that has been printing photos with the green hue. I've replaced the toner with new HP cartridges, uninstalled the drivers and software, checked the settings, cleaned the printer, with settings and modes. It still prints photos green weather I scan and print or through either my two computers or my iPhone. Hate think I have to take it for service if it's something I can fix. Any suggestions I can try. I've heard that in some cases it could be a hardware issue. All thoughts welcome.
