• Turn on the printer. Load the printer with media and press the feed button to ensure that the
printer is properly connected and the media has been properly installed. The printer will be
able to print as long as the vehicle power stays on.
The power supply can be located on any convenient surface within 1.42 ft. (0.43m) of the
printer. Locate the power supply where it will receive adequate ventilation. Do not locate it near the
operator’s feet or where it could hinder operation of the system or vehicle controls. Ensure that the
cable routing does not invite damage to either the charger or the printer.
