HP A7W94-67006 is a 128GB eMMC module for printer service and storage replacement. HP’s installation guide identifies this exact part number and explains how the eMMC is removed and replaced in a printer.
The guide describes the module as detachable from the main PCA: it pulls straight off, and its holder is removed separately. The same procedure explains that a replacement eMMC is installed by reversing the removal steps. This makes the part relevant when servicing a printer that uses this specific module. The guide does not establish compatibility with particular printer models, so no model list is stated here.
