Chapter 44-24.1.3 Major Components (iR2030i/iR2030/iR2025i/iR2025/iR2022i/iR2022) 0017-5568iR2022i / iR2025 / iR2030 / iR2022Major components of the original exposure system are as follows:F-4-1T-4-3Carriage positiondetectionContact image sensor (CIS) HP sensor (SR401)Magnification range 50% to 200%Vertical scan direction: Image processing is by image processor PCBHorizontal scan direction:BOOK mode: Carriage movement speed change and imageprocessing by image processor PCB *1ADF mode: Original feed speed change and image processing byimage processor PCB *1Lens Rod lens arrayCMOS sensor Number of lines: 1Number of pixels: Total 7488 (incl. 7176 effective pixels)Maximum original scan width: 304 mmCIS drive control Drive control by reader motor (M401)Original size detection [1] BOOK mode: not used[2] When ADF is usedWidth: Detection by original width sensor PCB in ADFLength: Detection by photo sensor in ADF*1 The control method depends on the magnification. For more details, refer to "Magnification Change".Component No. Function/Specification[1] Copyboard cover open/closesensor (Rear: SR402)SR402 Photo interrupter: Detects the copyboard cover open/close status. Starts detecting the original size when thecopyboard cover angle is 30 deg.[2] Reader controller PCB - Controls drive of the reader unit and image processing.[3] Original sensor 3 SR406 Detects the original size (for all destinations).[4] Original sensor 4 SR407 Detects the original size (AB, INCH/AB).[5] Original sensor 5 SR408 Detects the original size (INCH/A)[6] Reader motor M401 Pulse motor: Controls drive of the carriage.Item Function/Method[6][4] [5][3][9][8][2][1][12][7][7][11][10]
