Yellow imaging problems

[Richards]

I have a Konica Monolta c450. The yellow is not laying down very well. When I clean the IU it works better for only a few copies. Is this the IU unit htat is the problem or could it be the transfer belt? (all other colors appear just fine)
Thanks

Thanks, I will check into that. I have not broken the IU unit down yet - too new at this.
Would love to get a copier rep, but the only ones I know of around here would simply start changing parts and I am trying to cut down on my costs.

If all the other colors are OK and there are not mixed color dirty lines, then its safe to assume the transfer belt is OK.
