In the first two months (2 years ago) I had to replace the drum 5 times because of a printer design problem - causing streaks on page. Now 2 years later the printer reports that the drum is full of waste toner and must be replaced.
I'm trying to clean it and reset the NVRAM instead.

Need to change all the drums, but you can keep your old drums just reset the printer but your print quality will not be the best, after you change or not change you need to reset the counters. here is more information from brother
if ur using same unit by changing only drum for more than 2 / 3 drums
u need to change whole at once
the charging grid and wire can also damage ur drum
or is their any leakage in developer unit check for that also if developer appears on drum unit also damage ur drums make 2/3 print check any rough material on ur drum cartridge solving these 2 issue can solve ur problem
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.
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.
Generally speaking the lower coverage you print the longer the drum will last because it is not discharging and charging the entire thing the all of the time.
However, this gain may be negligible because it also depends on the quality of paper used and the drum type. For instance OPC drums last a short time compared to a-Si drums. So there are small things you can do but if you can't change what you run you are about stuck with that drum life.
Keep in mind that some sites may tout that their drums last longer but always take non OEM specs with a grain of salt.
