ADF Unit/Scanner Unit (WF-7620/7610 Series)
The ADF hinge spacers are inserted to the hooks on the ADF hinges to prevent the ADF Unit from disengaging from the Scanner Unit by the shocks
caused when the ADF Unit is opened or closed. When the ADF hinge spacers are set in their regular positions, the hooks on the ADF hinges cannot
be released; however, by turning the ADF/Scanner Unit upside down, the ADF hinge spacers move from the regular positions, and then the hooks on
the ADF hinges can be released.
When removing the ADF Unit/Scanner Unit, place it with its bottom up and release the hooks (x3) shown above in advance.
When installing the ADF Unit/Scanner Unit, make sure that the ADF hinge spacers (x2) are inserted at the hooks (x2) on the ADF hinges.
