SOURCE: Copystar cs-2550 drum replacement problems

ok. try this, take the rear cover off, theres quite a few screws. what i'm thinking has happened is you may have pushed the contact for the main corona wire out of place. this board is pretty flimsy. once you have back cover off, the board will be slightly to the right of center as u r looking at machine from rear. i can't recall EXACTLY what board looks like, but if you loosen your drum unit and have someone pull out drum a little and push back in, you will see what and where i am talking about. i'm a tech and had this bite me in the behind one time. will never forget it. hopefully, that will take care of it for you. let me know what you find.

good luck,

SOURCE: Copystar CS-1815 waste toner

There are two screws on the drum unit. They are on the left hand side and one on the right hand side. Remove the screw from one side and take off plastic small side cover. Dump the waste toner. Do the same for the other side and then put it back together. Turn machine off then on and the error code should be gone......
