We've had this Canon Imageclass MF267dw for about a year now, Recently, there is a crackling / crinkling /plastic noise whenever we send something to print, starting as soon as the machine 'wakes up' to print.. I opened all doors, removed toner and drum, the noise is present when those are not in the printer. I closed all the doors and when the machine tried to get itself sitauted, the same noise was present - towards the rear of the machine . I checked the rear flap with (obviously since i'm posting about it here) no success. Itt sounds like a small, flexible piece of plastic/ vinyl is catching on a wheel/gear - it is rythmic . One coworker said it sounded like mice. None of the visible parts (when opening the various doors) have anything wrong with them. Changing out the toner cartridge did not change the noise, which was present even without comsumables in the machine. Prints have not changed in quality. I used to work in a copy center, i'm comfortable hand actuating various gears to get small pieces of caught paper out - I couldn't find anything, and frankly, it's embarrassing. Thanks in advance for any help.
