My HP p4515n is printing out faded pages with the area that is supposed to be black, printing white, and the area that is supposed to be white is printing black, but it is all very faded. I have turned off economode, I have installed a new fuser, toner cartridge, and transfer roller. here is a link to a picture of the configuration page that I have printed directly from the printer's built-in menu:
