– 28 –
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.
