Here, read spock's answer, different model but same faults:

Also I believe front bushings are modified, there's bulletin about that somewhere.

Newer Konicas are easy on that, you only need to run Gradation Adjust after replacement of dev unit.

I've had 2 calls for this issue in the last week both times I replaced this sub hopper.

Check the toner bottle is rotating have seen the motor that drives it fail.

Re: c224 error c-2557

Take out black Dev unit and see if developer powder is missing (turn mag roller and see if even toner on roller). It may have dumped.

Keep in mind as mentioned on this forum many times, if "any" consumable is over life or bad they can affect "any" other color! Are any other consumables at 0% ? This is a chance you take when you turn off consumable reminders. Still way ahead of the game if this happens once during the life of machine.
