Any of these hardware changes require attention to detail on the PCBA assembly to
prevent damage. Some configurations require cutting an etch on the PCBA and solĆ
dering. These changes should only be performed by a trained technician.
Side Panel Removal - Floor Cabinet Model
To remove the right side panel, perform the following instructions and refer to Figure 3-2.
1. Turn the printer off and disconnect the ac power cord.
2. Raise the printer cover.
3. Disconnect the two ground wire connectors (A) from the corners of the side panel.
4. Loosen the side panel release screw (B) with the Phillips head screwdriver. Do not reĆ
move the screw; simply loosen it enough to slide in the notched cutout on the frame.
5. Using both hands, lift the side panel up and out from the bottom edge. The panel fits
snugly on four mounting studs (C). First time removal of the side panel may require extra
pressure to unseat the studs from the panel keyholes (D). The card cage can now be acĆ
