Question about Brother HL-4070CDW Printer
Try cleaning the wire grid- sounds like you have some gunk on the corona wire- in the printer under the toner cartridge is a wire grid that charges the paper before toner is applied- if there is gunk on those wires, you will get the smudge you described. You may want to use an antistatic brush and you *WILL* need to remove the power from the printer. Also, if you have one, a vacuum approved for both ESD and capable of vacuuming toner- don't use a standard shopvac, bad things like toner stuck in the motor of the vacuum and causing fire may occur. Fair warning, be prepared for something nasty- last time I had an issue similar to that ended up with me pulling a toner-caked, extra-crispy palmetto bug (Think of your standard cockroach, then triple or quadruple the size.) out of the corona wire.

Check on the toner and lift the lever to open the part covering the roller inside. It might have filled with ink or it needs cleaning. You can wipe it clean with a soft microfiber cloth then try printing again if it made any changes. If yes, then you may need to change that toner.
