PHASER 3124 / PHASER 3125
Hardware Structure and Descriptions
The printer is basically controlled by the main PBA. The Phaser 3124/B main PBA uses a
Jupiter4E processor while the Phaser 3125/B and Phaser 3125/N uses a SPGP V3 processor.
The processor provides integrated printing functions such as the printer video controller, laser
scan unit controller, PWM controller and bi-polar stepper motor controller and has USB and IEEE
1284 parallel interface capacity.
