The HP HPI 220V Fuser Kit (B5L36-69001) is a replacement fusing unit for compatible HP Color LaserJet Enterprise printers. It uses heat to melt toner onto paper during printing, helping create durable, smudge-resistant documents.
This version is rated for 220 V. The listed compatible printer families include Color LaserJet Enterprise M552, M553, M577, M554 and M555 models, as well as devices in the E57540 series. The fuser supports the printer’s toner-fixing stage, making it a service part for maintaining those printers’ output.
