Re: MPC4501 lines color copies

Does that happen only when copying and scanning? It might not hurt to pay closer attention to the wiring to the exposure light source.
I suppose it could be the SBU, but until you confirm that the exposure lamp is getting power throughout the entire scan I wouldn't worry about that.
If that happened on the actual internal prints from the pictures you shared though, it is more likely that that is a problem with drum charge.
