I HAVE JUST BOUGHT A Konica Minolta MAGICOLOUR 8650DN MACHINE WITH THE FS-519 FINISHER. TAKEN THE FINISHER OUT OF THE BOX AND FOLLOWED INSTRUCTIONS TO ATTACH IT TO THE PRINTER. WE USED THE PRINTER AS A STAND ALONE FOR AWHILE, SO I KNOW THE PRINTER ITSELF IS FINE. ONCE ATTACHED AND BOOTED UP, THE TOP OF THE MACHINE MAKES A TERRIBLE CLATTERING NOISE AND HAS GIVEN OUT TWO ERROR CODES, THE FIRST C-11BO, THEN C-1183. THE SOUND IS COMING FROM THE NEWLY ADDED UNIT ON TOP OF THE MACHINE. WE HAVE BEEN CAREFUL TO FOLLOW THE ASSEMBLY INSTRUCTIONS TO THE 'T'. I HAVE OPENED AND SHUT THE FRONT DOOR, MAKES NO DIFFERENCE. ANYONE ELSE HAD THIS? REGARDS, JIM

C11BO Did you remove the screw that secures the stapler during shipment. Open Front door if the stapler is unable to move. Turn the green know. Remove the screw. Also check a make sure that stapler cartridge is full engaged in the stapler.

C1183 The bottom exit tray is not engaging the top sensors. Remove the the back cover. Looking at the back of the finisher. In the upper right is Motor that drives the bottom tray there is a White gear assy. (FIRST IF YOU DIS ENGAGE THE White gear the TRAY WILL SLAM TO THE BOTTOM) so when you dis-engage (Pull the gear part be sure the prevent the tray from falling down. I used my knee:) Be careful the grease is nasty. Now raise the tray to just bearly touching the sensors where it can go no further. If not then you might have a bad motor or finisher board. Also check the two sensors that tell you the bottom tray is full. They are across from each other at the back of the tray front and rear.

C1183 is for Finishing Option Elevator Drive Failure. Most of the time when I see this code it is because 1 or both bins are not fully inserted into their slots. The bins when all the way in will trip small switches to tell the machine where the bins are. In your case this may not be true due to the noise you are hearing unless the elevator has already driven the unit all the way to the top or bottom.
C11BO is for Finishing Option Stapler Unit CD Drive failure. I have never seen this code come up before but as you can see, both of these codes are coming from the Finishing Option which you have just installed. It is very possible that the unit has some shipping or other damage and there is nothing you have done wrong. If it were just the C1183 I would feel differently.
I would start by checking the stapling unit and make sure that you got the packing tape and materials out of the inside of the finisher that hold the stapling unit during shipping. Most likely the 1183 code was from the bins but I am not sure of that as it could also be a shipping damage issue. Hope this helps!
Good Luck and Thank You for using Fixya.
