    C3320i wakes up exactly every half hour

    Hi all,

    I'm new here. I bought a C3320i and have a strange behavior...
    Exactly evry half hour the printer wakes up from deep sleep (<1W), display goes on, i hear e few noises and the printer uses peak >1000W for a few seconds, and then it resumes sleep after a minute (i set the minute sleep timer). It uses 33W then and after 10 minutes it enters deep sleep <1W again. Then after 30 minutes, it all starts again.

    Now i have checked and checked again settings in the web interface.... but nothing leads to the correct behavior and disabeling this strange wake-up behavior.

    Could it be that my all-night power PCB is broken?
    Would new firmware fix this?
    I greatly appreciate all help!!

    Thanks!
