    We do too. There is an issue, they just do know what the solution is to it yet. Open and close the wtb door and it resets.

    Re: False waste toner full, New boxes

    We just had a customer with a 4002 that threw a C7980 which is not in the S.M. This code pops up if the waste toner full sensor detects the full (lock-up) of the waste toner box 4 times continuously ( see QA H072 ) . The customer started having false waste toner full only AFTER they used the empty K toner container. They were able to remove the container "shake it" reinstall it ...this would work for several days and were doing this for several weeks , they only called in a panic after the C code.. I will update on what we find...

    Cheers....

    currently having this problem on multiple 3252ci models, on some U155 calibration have corrected the issue, other machines continue to show TWB full message even after calibration and bottle replacement.

    Here you can understand the root cause and fixes of the many erroneous waste toner scale and door messages related to the sticky sensor arm

    V2.05 firmware change notes:

    "Corrective measuresfor misdetection of thewaste toner FULLBecause of misdetection of the piezoelectric sensor, [Waste toner box is full] display or servicecall C7980 (piezoelectric sensor error) might occur. The overflow detection by the piezoelectricsensor is no longer used."

    i had this problem on both 4002i and 5002i, hopefully this update is it!

    Evidently they can’t figure out how to fix it, so they just disabled the sensor ?
    Hope that helps !

    the sensor was redundant, since there's a scale too. I guess they just wanted to be extra sure that the tank was full in case the scale didn't register full, and save the augers from piling-up.
