A recent problem with my 4250n printer: there is severe blotching and excess toner on the left side of each page. Cartridge is genuine HP, not new, been running fine for a while. Removing the cartridge, I see excess toner on the black roller right on the bad side.
Looking at the cartridge, there is excess toner buildup on the green roller on the problem side.
I have cleaned everything out and the problem returns. Printing several pages does not resolve it.
See pics attached. Any help appreciated.

One of the mylar blades in the cartridge has failed and is allowing toner to run out into body of printer. Replace the toner cartridge ASAP before the excess toner causes issues with your fuser.
