Removing Printer Connectivity Modules
Connectivity modules can easily be removed for the purpose of reconfiguring a printer or
repair. You should not remove and replace connectivity modules as a general practice.
1. Remove the interface cable (Ethernet or Serial).
2. Remove the module access door. Push down on the top of the door with your finger tip. This
releases the latch. Pull the door away and down to remove.
3. Re-attach the interface cable to the connectivity module and secure the cable.
4. Gently pull on the interface cable that is secured to the connectivity module. Slowly pull the
module out of the printer.
5. 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.
