originally it had cq problems, rescheduled for maint kit a and b. before i can get back they called in for blank copies and prints. went with kits and sure enough black is blank, i checked my contacts for black, put in the new k dev unit and swapped the drums around but no luck. im not getting any codes but im going back with the toner motor assly and the drive motors for k dev unit and k drum. ideas appreciated.
