3.1 Basic Constraction Chapter 3 3.1.1 Specifications, Control Methods, and Functions T-3-1 0012-7060 Item Function/Method Exposure light source LED Original scan In BOOK mode: Original scan is performed by moving the contact sensor (CS). When ADF is used: Original stream reading is performed with the contact sensor (CS) fixed. Scan resolution 600 dpi (vertical scan) x 600 dpi (horizontal scan) (Color send: 300 dpi horizontal scan) Gradation 256 Carriage position detection Contact sensor HP sensor (SR401) Magnification range 50% to 200% Vertical scan direction: Image processing is by image processor PCB Horizontal scan direction: Carriage movement speed change and image processing by image processor PCB Lens Rod lens array CMOS sensor Number of lines: 1 Number of pixels: Total 5148 (incl. 5104 effective pixels) Maximum original scan width: 216 mm CIS drive control Drive control by reader motor (M401) Original size detection no 3.1.2 Major Components 0011-6038 The original exposure system consists of the following major components: - contact sensor used to read originals - reader motor, drive pulley, drive belt, carriage, and carriage rail used to move the contactsensor - The analog processor PCB is used to convert the analog image data colleted by the econtact sensor into digital image data. The image reading mechanism is controlled based on the drive signals from the image processor PCB, thereby moving the contact sensor to read the original placed on thecopyboard glass. When the ADF is used, the contact sensor is moved to stream reading position, and the originals are read when they are moved by the ADF.
