Connectivity modules can easily be removed to reconfigure or repair the printer hardware.
You should not remove and replace connectivity modules as a general practice. It is not part of normal printer operations.
If you do have to remove the modules:
Unplug the Ethernet or serial interface cable from the printer.
Remove the module access door by pushing down on the top of the door with your finger tip to release the latch. Pull the door away and down to remove.
Re-attach the interface cable to the connectivity module and secure the cable.
Gently pull on the interface cable that is secured to the connectivity module. Slowly pull the module out of the printer.
Install a different connectivity module or re-install the connectivity module’s access door. Align it to the bottom lip of the access opening and swing it up to snap and lock in place.
