    Wox is probably right but something else is going on as well with the voltages, etc. I think you should look at laser unit you replaced to why it changed to blue. If the picture on right is what you had first had I wouldn't think that would be caused by just an image unit. perhaps trans belt and contacts, etc. When I have seen dev units dump the lines are usually diagonal. If all the consumables are not over life than I would look at the HVPS as well.

    dev units have lost the dev amount. you will need to replace the one or all that are bad. this comes from not getting enough toner or HV could be bad and if the drums are way over due.

    Took in a C452 as a trade in from a customer, the image below is how is was printing when I first got it. I’ve since swapped out a few units from a 652 and also a printhead. After swapping out the laser I got the blue defect. That’s is the test page of the birds BTW. Wondering if one of the boards have gone bad.
