I have replaced both heads in my Mutoh Falcon Outdoor 62. When doing an initial ink fill I am getting ink through Lt. Magenta, Lt. Cyan and Yellow from head #2 which loaded the ink automatically during initial ink fill but aren't getting any ink to head#1. The ink cartridiges are used, but are about 80-90% full. Have tried to draw ink through tubes using the syringe method and still can't get any ink to come through the tubes. Anybody have any ideas?
