Question about Gestetner - DSm660 Digital Imaging System Copier
SC412, 413, and 416 are development errors for cyan and yellow. If you open up the front door, there is a release lever (I believe it's blue) located on the right side under the far right development unit. (The lever has a squarish handle.) Make sure this lever is vertical with the handle facing upward.
If that lever is not the problem, you may have toner density issues and you should have a service technician (one who knows what they are doing) look at the machine, but most likely if you reset that lever the problem will go away.
Hope that helps!
