DC controller PCA The DC controller PCA controls the operation of the product and its components. The DC controller PCA starts product operation when the power is turned on and the power supply sends DC voltage to the DC controller PCA. After the product enters the standby sequence, the DC controller PCA sends out various signals to operate motors, solenoids, and other components based on the print command and image data that the host computer sends.
