    SP C811DN replace toner cartridge

    Hello all, I have a sp c811dn that keeps saying replace toner cartridge black. It says toner loading for a couple of minuets then says replace cartridge. I replaced the pump unit K with supply tube (this has always fixed before on other machines) and I replaced the toner end sensor. It still says replace k toner cartridge. Any input would be appreciated. thanks in advance.

    I would replace the k toner pump, as a test you can swap it for one of the colour ones, slightly different pipe angle but it will fit.

    In the original post he said pump had been replaced.

    not sure being a charge call I only see this machine once a year or so. I guess I could check the counters if they reset when new unit is installed

    My bad, I read his post as replacing the pump tube only.

    Change SP 3045 to 1. If the printer starts working, you have a bad RFID board.

    you have a sensor that give you the same problem that is this

    B223 3205- Nozzle Ass'y

    this give the same problem but you can change with other color and test then go to developer.

    RF board only detects if the toner cartridge is there or not

    Guess again. The RFID board reads the remaining toner value of the cartridge. If the value is 0, either because of a defective cartridge or RFID board, the machine will display No Toner and immediately disable printing. Changing SP 3045 tells the machine to ignore the RFID board and rely on the nozzle sensor. When there is no more toner, a pre end condition will be generated and the user will be alerted to replace toner soon.
