These are going machine through landscape. Anybody ever seen anything like this? The samples are sky shots. The cyan and yellow have the bands
going across page in same place every time. the magenta is light. I've tried replacing transfer belt, drum and developer units and HVPS. Oh and I swapped the engine board. Nothing changed.

Also, the bands start out at the lead edge. Solid area is trailing edge. Same place every time.
How is black? what exactly do you mean by "sky shots", I'd expect sky shots to be black, or an approximation thereof. Can you do sim 89 "sample set"? have you looked at the LSU units for cleanliness?
Have you looked at the latent developed image on the primary transfer belt? Can the missing portions of the image be seen on the primary transfer belt?
If the image on the primary transfer belt before transfer looks exactly like the image on the paper ... stop it sooner. What does the latent developed image look like on the cyan and yellow drums? =^..^=
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.

Looks like a laser issue.
we talk about copies? Have you also done an internal test print?Originally Posted by copierjeff
Best not to do sky shot. Best solid black page on glass then select single colour gives a better result

Here is status page. I made previous samples with sky shot on single color mode.
Black is actually fine.
Looks like a transfer pwb , replace the transfer pwb and or check the spring contacts on the same pwb
