3.2 H/W Structure and Descriptions
3.2.1 H/W Overview
ML-2510/2570/2571N is roughly made up Main Control part and SMPS/HVPS part.
Main Controller uses Jupiter4E for ML-2510 and SPGP V3 for ML-2570/2571N, which is on chip micro controller
and developed for Low-end Laser Beam Printer.
Jupter4E and SPGP V3 provide provides the integrated printing functions such as Printer video controller, Laser
Scan Unit controller, PWM controller and Bi-polar Stepper Motor Controller and has USB and IEEE 1284 Parallel
Interface capacity.
3.2.1.1. Main Control
ML-2510/2570/2571N of Main Control are composed of CPU and Print and operate follows function by CPU
- Bus Control, I/o
- Handling, each Driver and PC Interface
Main Control operate its full function on the Main B'd and CPU control Controller ASIC.
3.2.1.2 CPU
ML-2510 Use 32Bit RISC Processor of Jupiter4e, which is built in Memory, while ML-2570/2571N sue
SPGP V3, They control system by operating operation block of the system.
