The Color LaserJet 4550 DN has two maintenance parts here: the C4196A transfer kit and the C4197A 110V fuser kit. They address separate service messages and should not be treated as interchangeable supplies.
Toner Buzz carries genuine HP C4196A and C4197A kits for the 4550 DN. Use the component and code named by the printer to decide between transfer maintenance and fuser service.
