Chapter 1 Product Overview Power Switch Cover Install the power switch cover that comes with the TM-T88IV onto the printer to prevent inadvertent changing of the power switch, to prevent tampering, and to improve the appearance of the printer. To reset the printer when the power switch cover is installed, insert a long, thin object (such as the end of a paper clip) into the hole in the power switch cover and press the power switch. WARNING If an accident occurs with the power switch cover attached, unplug the power cord immediately. Continued use may cause fire or shock. 1 Control Panel (POWER) LED ERROR LED PAPER OUT LED FEED button LED POWER LED (green) • Lights when the power supply is on. • Goes out when the power supply is turned off.
