Hello,
Also sorry for reresurrecting this, however it literally was the top result of my google search result as well. I had the same issue with a cyan toner cartridge for a Kyocera M6530cdn.
TLDR: Never shut down printer during new toner initialisation. If fails, put old toner back in. put new one back in. Verify.
Our issue was somewhat similar or different. Replaced the toner and waste toner bottle. The initialization took about 2 minutes with no end in sight. Restarted it. Initialisation was finished. Printed a test page. No colors. Printed the printer report / config. Cyan still 0%. Removed the cyan from the printer and put it back in, no initialization. After some restarts and verification attempts, we put back the old one, which gave us a message that it was not a genuine toner (for whatever bloody stupid reason) then initialisation started, a colored page came out that was waiting, then we placed in the new full toner and presto, it was recognized and working.
Also thx for having such a useful forum. I hope many more people will find there solution in here.
This may actually work for more than just Kyocera, but also HP, Oki, Konica Minolta and any other printer with such issues.
