      The problem is that toner is not being dispensed to the developer. Every time I have seen this it has been the toner in the tube is compacted which prevents the toner auger from rotating. It happens on the 3030 series also. Go ahead and really shake up the toner tube to loosen the toner so it will flow freely. Then physically rotate the toner auger from the rear of the tube. I use a large standard screwdriver rather than trying to grab it with my fingers. If the auger will not rotate you will need to install new toner. Also, check to see if the toner motor is actually turning on. If not, you have bigger problems.

              Another thing to check is the auger from where the toner drops from the tube and is auged into the dev unit. Make sure it is functioning ok. Also, the drive for the auger gets stuck and does not contact the drive from the machine (spring loaded).
