Question about Konica Minolta Office Equipment & Supplies
Error code C2551
I have found that if you don't use make a lot of color copies the toner can bind up in the cartridge. Pull out the cyan toner, shake it up and tap on it, and reinstall into copier. This has fixed 99% of problems with this error code and the others related to TCR sensors for colors. If it is a new toner make sure the black gear didn't fall off of the back of the cartridge.
