Re: bizhubc452

Try running skew reset. You may need to replace the LSU driver board. That solved a similar issue I had with front-to-back registration on a C452.

I actually replaced the belt sensors at the same time as the driver board, but I'm pretty sure the driver board was the issue.

Re: bizhubc452

l1,2,and 3 are you need to replace the C M and Y image units, dont chip them like a cheap ripoff thief, replace them with OEM. D1 is usually a dirty slit glass or the white strip it calibrates from.
p21 is failure to calibrate registration.
im sorry if i sound like a primadonna but chipping consumables is just theft to me. if your click charge does not cover the cost of these units over time you must be a lousy businessman. if it does cover the cost with profit at the end you are just a thief trying to get more money. how do you sleep at night?
my comments arent directly at you, i just see tons of chip reset posts and it make me cringe. if you only use OEM, thank you for your proper service.

Re: bizhubc452

Colors are Cloudy too, replace image units, can sometime help with Color shift otherwise, under Untility Key, then Adminstrator mode goto expert mode and fix registration manually. Procedure is in the Service Manual.
