    image runner 6550 blank copies please help!!!

    hey guys i have a canon image runner 6550 that was given to me that produces blank copies. i have tried replacing the toner/drum/charge unit but still no luck. any ideas on this problem would be greatly appreciated. also i stopped copy half way through to see if image was on the drum but no image was there. so i know i have a problem there. and since i replaced the toner unit which has the drum and main charge in it, i know its not charge. thanks in advance for the help.

    Since you hard stopped the machine and checked the drum for an image, the fact that no image was present suggests you have a development problem. It could be developer bias, lack of toner or the developer unit.
    You say you replaced the charge corona assy, but you may still be missing charge current. These are the areas you need to check.
    Let us know how you make out.
