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

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.

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.

11. WHEN POWER IS SUPPLIED BY THE USER
