A bran new (1 week old) Canon Color Image Class MF643CDW is scaring every one in the house by kicking off a continuous grinding noise on its own in the middle of the night with absolutely no one touching it nor any pending print job. This has happend 3 times in the one week since i have this unit plugged in.
It happened the very first day just hours after setup and succesful 4-5 test pages. suddently it started the grinding noise that sound like it's about to kick of a print job, only that it keeps going and going non-stop. I took as possibly it's part of iniitial self adjustment.
The second time, I got a call from my wife in the middle of the day because she heard some squeaky sound and thought our AC or washer has gone wild, only to discover it's a printer.
Then it happened again a few days later this time in the middle of the night and had everyone startled as we all run around the house trying to figure out what is making the weird noise, check alarm, check smoke/carbone monocide, before finally coming to the room with this printer blarring.
Each time, i had to power off/on to resolve it. But this is not normal and i cant continue with this. I need a solution to it ASAP.
