D22-542 is saying that there's a problem with the printed circuit board on the print drum. It's not communicating with the machine. D04 -534 says that the incorrect ink cartridge is installed. First, is this a new drum you are introducing into the machine? if it is, not all drums are interchangeable. You need to get the right pcb (printed circuit board) for the ink drum you are using to match your machine. Second.. Something is mismatched here with the ink cartridges. The only way you'd get the ink cartridge error is if the drum is in the machine. I had this problem with a Rn 2130 ui.. I bought a used drum off e-bay and it wouldn't work. When I stole the pcb from another color drum it worked fine. If you have been using this drum in this machine before... be sure that the connection between the drum and the machine is good. Make sure you have the right ink cartridge too. Some of these aftermarked re-sellers sell stuff that doesn't line up with the tabs on the inside.. I've got some ink here that if you hold your toungue just right and turn the tube about 2 degrees it'l work.

Can a red drum for an RZ200 be converted to a black drum.

I am am currently not familiar with this model yet. But I have done such a procedure on other models already.
Please consider how to remove the unwanted colored ink. Do you want to dismantle and clean the whole drum mechanism? Or do it by printing several hundred (tousand) prints with high inkage? (You might discover some nice color effects.)
Some questions for you to make it clear: Does the black ink bottle fit in the color drum? Yes? Continue! Compare the PCB (unscrew the plastic housing) of a black drum with a color drum? Identical? Continue! Set DIP switches on PCB like the black drum. You are ready to use black ink!

go into test mode..
turn off machine and turn it back on while holding down the left and right print position arrows.
if the error code shows up.. press the yellow reset button to clear it.. you will then see a number (firmware ver.) press the "C" button on the number pad..
you should then see the display all zeros "0000"
enter 890 and press start.
then when it beep press the "C" again enter 112
when it beeps again press and hold the yellow clear button and the machine will reboot...
i am sorry to say that if this did solve the problem you will need replacement parts or a new drum
