    There is a firmware fix for this SC, I suggest you begin by updating the firmware.

    If that does not fix it the rubber transport auger many have flipped out of the toner hopper.

    Its a messy job but I have seen this a lot on this device

    Make sure that the pins that touch the RFID chip of the toner bottle are not bent. I have encountered that kind of problem. I have found out that one of the pins is bent and it is not touching properly the RFID chip.

    SC 681.pdfCheck the tech bulletin for this issue. It involves a new kind of tension spring for holding the toner bottle

    There is a new bulletin for this - a spring in another form in the function, that turns the toner bottles.

    We have this issue before, it was intermittent error. We replaced the development unit, toner hopper, D1495174 - PCB:TCB, toner cartridge, springs(Tech Bul) and updated the firmwares
    but the error still appears after some time. What we did is manually initialized the td sensor - SP 3030. Machine now ok. I cant see any RFID on the machine.
