    C3300i/C4000i/C3320i/C3350i/C4050i Fan (FM3) issue

    Hello, i have some sparrow machines with this problem:
    When the device is in sleep mode, and apparently without any reasons, the FM3 fan runs for a 1 min stops a 1min and so on.
    Does anyone have a solution for this problem?

      At what FW version Sparrows are? Earlier i-series FWs are full of problems.
      A tree is known by its fruit, a man by his deeds. A good deed is never lost, he who sows courtesy, reaps friendship, and he who plants kindness gathers love.
      Blessed are they who can laugh at themselves, for they shall never cease to be amused.

              I confirm that I have had this problem. But with the printer turned off! Yes, you got it right. I turned off the main switch and the fan continues to run for 5-10 minutes. I usually resolve by unplugging for 10 seconds.

                  These printers keep a small voltage running through them even when powered off but still plugged in. There is a bulletin on Infohub something to do with quick start

                      Yes, I am aware of this. But I think this is strange. Usually it doesn't. When this happens it's because the printer freezes (goes offline, unknown jams, etc.)

                          As I understand it the fan starts when there is some network activity. I found the the fan starts more frequently after I activated AirPrint.
