Hi guys, I have an MP c5501 with SR 3020 booklet finisher. after only x2, 2 page booklets (a4 or a3) get message booklet tray full, after removing booklets, the message remains. I have changed the sensors, harness, control board, checked firmware, ensured all brackets are straight. I can get rid of the message if i reset m/c ....Any Ideas ??
