have you tried single colour sky shots to see if the marks you are getting are different in each colour?

To me it looks like the transfer belt just isn't getting cleaned
We know a thing or two because we've seen a thing or two.

Chances of all IU's being bad is really slim, agree the trans belt is likely culprit.
FYI, Dirt on lasers would cause "blank" lines not colored lines. Always think the opposite with laser technology. What would cause black/colored lines with analog will cause white/blank lines with laser. Few examples, Dirty coronas- analog blank, laser black. Dirty optics, analog black, laser white, etc etc.
Do we have here in these series the much feared "Clogged Waste Toner System Syndrome" starting to show up?

Good thought Hans. This may be the calm before the storm (gears chattering). If the trans belt cleaning unit was thoroughly vac'd out and put back into mach then you should be able to get several clean pages before lines would show up again? Another thought, if you go to vac out the trans belt cleaning unit and it's not packed with toner then does that mean the machines waste transport is working ok? I would think so.
May be a longshot but reminds me of ripple in the power supply (open filter capacitor). It's hard to imagine that all 4 channels of the copier have identical failures. The final fix should be pose some interesting discussion.
Sorry all for not replying I've been side tracked for a few days 😂
I havent been been back to this yet so I'll try a few more things and let you know, probably just swap it out.
