Theory of Operation Phaser 3300MFP Operational Overview Summary 2-2 The Phaser 3300MFP is a monochrome multi-function product that uses Laser Scanner Unit (LSU) with an electrophotographic process in the print engine, a moving CCD in the automatic feed scanner, and a built-in faxmodem for fax functionality. The printer system consists of one print cartridge which creates toner image. The Phaser 3300MFP is roughly made up of: Main Controller, Control Panel, Scanner, Line Interface, and Power subsystems. Each subsystem is a separate module that focuses on common and standard designs of different kind products. The Main controller consists of 1 CPU and 1 Board. The Scanner consists of the ADF and Platen, and is connected to the Main Controller by a harness. The Line Interface Unit is designed to apply TBR21 standard (Domestic, Europe, etc.) 1. CPU: ARM920T, which is exclusive controller to execute Printer & FAX Function and to execute operation block by flash memory within system program, and to control whole system. ■ Main function block ■ Completely Integrated System for Embedded Applications ■ PVC - Dual/Single Beam, LVDS Pad (VDO, HSYNC), Support A3 1200 dpi, multi-pass color. ■ HPVC - Dual/Single Beam, LVDS Pad (VDO, HSYNC), Support A4 600 dpi, multi-pass color. ■ DMA - 6 Channels (if not use CIP4e, 4ch is available for external DMA. If CIP4E used (a4 DMA channel use), 2ch available for external DMA) ■ Operation Frequency: CPU Core -> over 300 MHz, System Bus -> 100 MHz ■ Operation Voltage: Core Voltage -> 1.2 V, I/O Pad Voltage -> 3.3 V, RTC Voltage -> 3 V 2. Flash Memory: Record System Program, and download System Program by PC INTERFACE. FAX for Journal List, and Memory for One Touch Dial, Speed Dial List. ■ Size: 32 Mbyte (NAND Flash) ■ Random Access Time: 10 us (Max) ■ Serial Page Access Time: 50 ns (Min) 3. SDRAM: is used as Swath Buffer in Printing, Scan Buffer in Scanning, ECM Buffer in FAX receiving, and System Working Memory Area. Size: 64 Mbyte (Basic), 96 (64 + 32) to 320 (64 + 256) Mbyte (Duplex) 20 MB: System Working Memory Area and Scan Buffer 6 MB: FAX Memory Receive Area 30 MB: Printing System Working Memory Area Max Frequency: 166 MHz Store Fax Receive Memory Data by using Battery Phaser 3300MFP Service Manual
