first off I am a technician and I do have the manuals on this model bizhub 423. today was the first time I needed to do a drum unit and developer in one. the service manual goes step by step. but it made it sound like you needed to replace the drum unit. then run the gradation. then the machine said replace developer. so you had to fist run a drum dry then reset. replace developer. reassemble then run a function. could these steps be done all at the same time.. ie just like the biz 350 drum and developer at the same time. then the functions? I guess I wasn't that happy at the yield of this machine. the predecessor biz 421 drums went 250k.. oh well thanks for any thoughts
