When printer power is supplied by the user rather than through the accessory power source unit, please be careful of the following points.

Note 1: The power supply must be +12V +10%–5%2A or above. An electrolytic ca- pacitor (C = 4700µF/25V to 6800µF/25V) must be connected across the output of the power supply.

Note 2: A DC power plug is available as an option.

GND

+12V

GND

Reference: Design the power supply referring to the power supply circuit shown below.

Note: A line noise filter must be used to prevent line transients from passing through power supply. Filter design to be determined by environmental noise requirements.
