What is the solution for EO13 of canon6050 - Office Equipment & Supplies

check the primary assembly maybe the primary assembly is not properly lock or the corona wire is broken, also check the transfer assembly maybe there is a leak on transfer or the coronawire is broken, if you already check those two check the developing unit maybe the magnet roller is not rotating

Hi,
Select running Windows in your PC and Download "SonicStage" and "MP3 Conversion Tool" from Sony Support
This will enable you to load songs in NW-E013 MP3 Player.

I have glanced at and passed by your question several times, and finally cannot resist the urge to answer. Canon copiers are unique in the fact that they are " monocomponent". This probably means nothing to the average person. But suffice it to say,the"waste toner" you speak of is primarily drum polish and paper dust, neither of which is very good at producing a decent copy. In fact, ANY percentage of waste toner introduced into the Canon copy process is a recipe for disaster. I primarily say this because at some point you will have to replace the development unit (or have some serious service) and probably replace the drum ($1000) if you continue. I am not a Canon employee but have worked on Canon equipment for over 20 years. I merely wish to help. I would be hard pressed to see how you can save enough money up front to cover the back end costs.
