Error code points to bad developer motor. Found that on the end of all the drums waste port is clogged and rock hard; filling up waste in toner cartridge. Also found gears for waste auger in back of 2 drums broke. Checked all couplers in back that engage the drum waste and they all turn when I manually turn the motors. checked motors with cover off and they all look to be turning correctly. Any suggestions would be great. Had already swapped out 2 drums previously for this.
