sounds like you have a blown ICP on the printer control board.

Have you got a print sample you can post?

Were they brand new from Konica Minolta or refurbished by someone?

New IU's should already contain developer out of the box and I don't know how you can tell that black and yellow toner isn't making it through the waste system as everything comes out a lovely brown colour as they are all mixed together.

It's easy to check if the developer is going into the waste toner bottle - just stick the screwdriver's magnetized tip onto it and check if developer comes out stuck onto it.

Did you do this?

And did you follow JSCs tip and check for blown ICPs?

After checking my documentation, here's the following:

Remove the PWB MC and on the rear side of the board locate ICP 16 & 17. Use a meter and check for continuity across these
components. ICP16 controls HV2 (developer bias) and ICP17 controls HV1 (charging and transfering bias). If you repair the ICP and it keeps blowing up, replace the HV unit that is indicated by the blown ICP.
