The HP 527G0A is the genuine HP LaserJet 110V fuser kit for HP Color LaserJet Enterprise 5700 and 5800 series printers and MFPs. The fuser bonds toner to the paper with heat and pressure, and replacing it at end of life restores sharp, well-fused prints and prevents smearing, wrinkling and jams. It is rated for up to 225,000 pages and is a planned maintenance part for high-volume colour printing. Listed compatible models include the HP Color LaserJet Enterprise 5700dn and X55745dn, the MFP 5800dn, 5800f and X57945dn, and the Flow MFP 5800zf, X57945z and X57945zs. Important: this is the 110V version for 110-127V printers; South African 220-240V models normally need the 220V fuser kit.
