If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

I'm agreeing with you on this one. We had a couple OEM 8-series drums a about 2 years ago with a cleaning blade issue that looked just like that. The lead edge of the smear had that arched look to it like in the sample. The only thing that the cleaning blade wouldn't explain are the couple lines at the top of the sample page.Originally Posted by blackcat4866
At the end of a job the drum is rotated backward ever so slightly. I assume this is to "clean" the blade, but I never bothered to look into why. In any case, on the drums we had the problem with it seemed like the blade was slightly flipping backwards during this reversal of the drum. When the next job came around the blade would have to flip back into its proper place, resulting in the arched smear on the very first page of every job. We tried using some drum powder on the drums, and it did work to clear up the smears for the next couple of jobs, but ultimately would return. In the end we had to replace the drums.

My Ricoh knowledge is slowly dwindling away at this point. Many things have been lost to time...
I had several drums do this. Pops up once in a while. New drum takes care of it
Never had it on a "4" series so if the drum as suspected it's probably that damn PCR !
I agree with Gift , Looks like it might be the transfer belt cleaning unit
My first thought was ITB too, but the other arguments about the drum are sounding very solid to me.

There are clues that gives away the ITB the clear band there the IDS sensor operates and the middle pawl that seemed to starch the entire circumference in my opinion. The lines on the top looks like the PCR from the drum.
My bet would be both ITB and drum. Who knows...
Is there any repeating intervals?
Does it happen consistently or only in the begin of print jobs, every page, every other page, after make was sitting for a while?
The shade looks worse towards the WTB side? waste toner is baking up in the ITB or may be drum?
Whatever
I had few times on 308e similar smear but smaller, like eyebrow shape about 1-2cm long.
In all cases drum was near end life or overdue.
Replacing drum solve problem.
ive seen the same stain pattern twice, i replaced both the transfer belt and the DV unit and it went away.
honestly couldnt tell you which one fixed it but it was between those two.
new drum made no change.
We know a thing or two because we've seen a thing or two.
Also don't ask me for files without a contributor badge.
Well I withdraw my ITB cleaning unit suggestion, too - please file it under "general cleaning recommendation"
