The Color LaserJet 4550 N maintenance products include the C4196A transfer kit and C4197A 110V fuser kit. The two codes refer to different assemblies, so the service notice should determine the choice.
Toner Buzz carries both genuine HP kits for this printer. Select C4196A when the transfer system is named, or C4197A when the message points to the fuser.
