2801-tcr level abnormality.toner flow from the hopper to developing unit is not correct
toner hopper may jammed . the sound is from hopper gear slipping while running. open the toner hopper section and check.

It was fairly common on that series for endusers to mis-align the toner tubes and get them seriously wedged in there. Does it rotate if you key the door? =^..^=
