How to reset drums on oki c5950
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
