HP A7W93-67050 Deskew Front Drive Assembly is a printer service part for the front deskew mechanism. It is identified separately from the rear drive assembly, so the front position is a key part of its identity.
The service procedure shows a motor and drive belt in the assembly, with a flat-flexible cable connection. It explains how to remove and replace the part during printer service.
The procedure is identified for HP PageWide 785z+, E77650z+, E77660z+ and P77940dn+ models.
