Re: Vertical Repeating Black Lines when Printing WorkCenter 7830

Hi Joe


After taking a more indepth look at the Drums and following your suggestion of swapping R1 drum with R4 the defect changed from Black Lines to Yellow Lines and as such after looking at the drum more closely I could see some lines on the drum itself.


I have left the R1 drum in R4 as now the yellow lines only appear when colour printing and no marks appear now when printing letters or black and white documents which will provide a work-around until the new drum arrives. 


Many thanks for you assistance as always.
