Docucolor 250 Black banding ?

[NuBankTech]

I'm not sure if this is called Banding. But starting a few days ago solid black bar is printed on each page now. About 3/4" wide.. across the whole page. Also the registration with the black isn't working out with other colors. Gives sort of a ghosting image. We've changed out the R3 and Black drums. We've also been getting fault codes. 042-326

That black solid bar is caused by the scorotron where it's home positioner is not moving. You may need to manually move the positioning/ it could have tilted. Otherwise, you need to change the scorotron cleaner motor.

Registration can be fixed by using the regi adjustment procedure under service mode.

ec042-326 is an IBT home position failure. You need to clean the IBT belt and cleaner assy. Clean the silver patch on the IBT belt, replace it if worn.. or better yet replace the IBT belt. reset NVM 741-105 to 0.

DC250 042-326 & IBT Cleaner

I have a DC250 that keeps coming up with the 042-326 error code. Have reset the 741 105 code but keeps coming back. Have checked belt but how do you access the cleaner assembly to hoover it out? Fairly green on this printer so any advice, service manual or even pics for guidance would be a great help.
