Internally Mounted Interface Cards Before you can install these you need to take off the upper half of the printer case to get to the main circuit board. WARNING High voltages are present inside the printer when the power is switched ON. Do not remove the case and install optional interfaces unless the printer is switched OFF and the AC power cord is unplugged from its outlet. Also, beware of touching contacts on the circuit board of the printer - many of the components are sensitive to static electricity and can be destroyed by the charge that may build up on your body. Removing and replacing the printer case 1. Turn OFF the power to both the printer and the computer, and disconnect the interface cable from the printer. 2. Remove the dust cover. Take off the paper feed knob on the right side by pulling it straight out from the printer. 3. Remove the ribbon cartridge. G-2
