This toner cartridge identifies as non HP and makes you jump through hoops ot make it workit also doesnt have a bottom protector to cover the platen roller that moves out of the way when you install it.I will never use this product again once i use up the ones i havethe quality is good but the NON HP issue is a big no for me
