Epson C900 colour laser printer (North Kelvinside G20)

This is an old Epson C900 networked colour laser printer which has served us well but now has a few smears on the printouts so is suitable either for someone who just needs draft prints or who wants to try to fix the issue.
The attached image of the printer is a scan of a printout from the device which might give an idea of the problem if you can zoom in.
I also have new developer cartriges: 1 Cyan, 2 Magenta, 2 Yellow and also a new photoconductor unit but no spare toner.
Print drivers are available for Windows 10 (and probably Windows 11 although I haven't tried).
The status monitor isn't available in the new drivers but there are a few workarounds for checking toner levels and total pages printed.
Dimensions (mm): 530h x 430w x 400d (and it is quite heavy!)
If no interest it will go to WEEE recycling.
