Disconnect the toner transport tubes in both ends and vacuum them, should resolve any possible build-ups of toner blocking them.
Vacuum the toner-end sensor (at the end of the black plastic thingie the toner is initially fed through).
Vacuum the above mentioned black plastic thingie, you'll understand what I mean when you take off the back cover and swing out the controller box.
Vacuum the toner pumps and clean the toner pump clutches.
If none of the above solves it, you may have a faulty RFID-board. |
