My Ricoh Aficio SP C420DN Laser Printer shows color tone SC366 and some time SC365, any ideas?
You just have a problem with colour PCU (SC 365 - magenta, SC366 - cyan). The main reason is that toner density is abnormal. Sometimes, when you replace toners, printer receive to much toner for a short time, and after that you have an abnormal toner density (higher). You can check in service mode (hold up and down arrows for 6-7 sec, release them and press ok button) following thing :
choose 2. engine
then with arrows choose 3. process
then choose Vt display,
for each color by default there should by somewhere arround 2.4V. If you see for some colors, for example 0.02V, then this is a problem(to much toner). In this case the only thing that you can do is to restart printer and try to print enough pages, filled with problem color. Usually you can print max 3 pages. Then restart printer and try another 3 pages. Print until the you will be able to print at least 4 pages continuously.
Good luck and remember that this is a technical problem and you should ask someone qualified for the job. I am sure that 80% of service engineers can't repair this issue. But I can.
