This is simple. You can't. Manufacturers make their money from consumables. They don't want you to be able to reset anything to get more life. The drums have internal fuses that blow when put in the machine, that's how they reset the counts. Sorry.

It sounds like the Fuser is bad. Try replacing it.

That message is indicating that you need to replace the black drum which also may have been what was causing your origanal issue. Whenever you have a print quility issue print four seperate documents each document using one of the four colors (black, yellow, magenta, cyan)used by the printer. If the problem only shows up in one color then that is where the problem is coming from.

Set it or computer, whatever you are using to cardstock, or it may be called thick,there are multiple selections depending on the media. Beacuase thick paper requires slower speed and hotter fuseing.

open up the front cover which will hinge down under the front display panel. The waste toner bottle is the black plastic thing under there.

Theres a blue catch to release it.

You need to do s head clean. This could take 2 or 3 goes but should fix it you will find head clean in the maintenance settings. It eats the ink so only do as you need. let me know how it goes. Regards Craig

If you printer has an additional memory card fitted then remove it (powered off of course) and turn on and see what happens. If the fatal error is still there then with the age of the machine (getting on in years) it is better to replace it as the error refers to the cpu in the control board and that's expensive on older machines to replace.

replace 1 fuser unit or 2 transfer belt

the best soloution is to replace the unit with a brand new one as reset fuses are difficult to work with on fuser units but if you search the internet you might be able to find a reset kit from alibaba or amazon

remove drum units and clean optical sensors located at the back end of he drum slots and clean corresponding reflective plates on drum units

your drum cylinder (opc) or dev roller needs to be replaced

Does not work on OKI C830. Get error message such as toner level error.

Amber's solution worked on an oki c5150 as well as on her 5500. At first, I got into other menus and did not see what she'd described. I cancelled out, then re-ran her procedure following its steps EXACTLY... At the very end, I may have seen one additional message - "EXECUTE" - which I "entered" to launch the process. Printer now works while I find instructions on how to replace "just the drum". The OEM drum assembly is very easy to change but costs about $125. I found (on Universal Ink & Toner) a drum-only replacement for $30, but there was no instruction sheet with it. This solution has allowed me to keep working while I figure out how to install the new drum. Print quality was excellent right up until the manufacturer's internal counter shut printing down. Quality remains excellent after applying the above solution. THANK YOU AMBER Dave
