I have a riso RP3100ui. I am looking to buy a used drum. Currently i use only black ink. I see used drums on ebay and alike but they are colored drums. Can I put a black in cartride in a rp3100 drum and live with the different colors for a while until it starts to print all black?

No.. A color drum is a color drum. You can change any color drum and re-program it to be a different color but you can't use a black drum for anything else. The RP is a sophisticated machinge and even the card inside the black drum is different. I think it would give you an error at some point.. Besides the fact you'd go through about a half a tube of ink before you got the new color.. I've converted color drums as you say.. even after 5000 sheets of paper I still have the old color on the sides and stuff. My local service shop changed one of my drums to a different color for $175.. I thought it was a good deal after doing it myself once. Helluva mess. You want to use a color drum as black.. Might work..maybe.. but I've never tried it.. If there's a problem with your black drum... buy a color drum and strip it for parts (except the printed circuit board) and get your black drum working.

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!

What is P-04-513 error code? The machine stops during run and posts eror code above.

I'm getting the same error. I heard somewhere else it was the ink overflow sensor but I do not know how to fix this.

It only happens with one drum, but based on a visual inspection the problem drum appears to be normal.

I need to know what buttons to hold down on a riso 390U in order to get a different color ink to print in a drum

That's almost correct. Risos have two kinds of drums: black and color. The black drums have to stay black. If you want to print color you need to a) buy the appropriate color drum or, b) change the color in a color drum you already have. If you change from, say, blue to red, you're going to have purple for a little while. It's not a really efficient way to get things done.

Riso Rz 220 copies are coming out to light.

1)You can set the dencity of the riso on the controll panel before you do your masters.
2)Always use original ink.
3)If you are a bit technical you can remove the pressure roller and strip all old ink buildup from it.was it with water ann soap.
If you open the drum and take it out completely,the pressure roller is the black roller inside the machine that put directly pressure on the drum.There is only one screw to loosen and then it hooked out,but it can be tricky to hook it back if you not doing it every day.
