The HP B5L46-60102 stapler unit is a replacement assembly for the stapling function in supported HP printers. It is intended for the M527c/f/z, E52545c/f/z, M528c/f/z and E52645c/f/z models.
The unit is installed inside the printer as a replaceable assembly. Once fitted, the printer’s convenience stapler can staple pages together, helping finish documents at the printer. This part is suited to restoring that stapling function when the existing unit needs replacement.
