Installing the Serial Port Module
1. With the module’s access door removed, slide the serial port module into the printer. Push the
circuit card in slowly but firmly until the card is just past the inside lip of the access door.
2. Align the bottom of the serial port’s door cover to the bottom lip of the module access opening.
Swing the door up and snap the cover closed.
