The HP B3Q10-40041 slider pin is a replacement part for the lift mechanism of an integrated scanner assembly (ISA). It is listed as a new part and is intended for use in the scanner assembly, rather than as a complete lift assembly.
The listing names the HP LaserJet Pro MFP M427DW, M427FDN and M427FDW among compatible models. This pin is a suitable service part when replacing the corresponding slider pin in a supported printer’s scanner lift mechanism.
