6 MECHANICAL FUNCTION 6.1. Paper Feed Mechanism (Auto) (Fig. 6.1.1) 1. When the documents are set on the Hopper and the scanning command is issued from PC, the Conveyor Motor will be driven to rotate the three Drive Rollers (Drive Roller 1 to 3) and Exit Roller. And at this time, the gate will open. 2.
Page 28
4. Then, the leading edge of the document advances to the Drive Roller 1 position, and then passes through the Slip Detect Sensor. At this time, if the document does not advance within a defined period, the pressure applied to the Separation Roller from the Double-feed Prevention Roller is strengthened to prevent the document from slipping.
6.2. Paper Feed Mechanism (Manual) When scanning multipart paper with the Manual Feed Selector set to “AUTO”, the Double-feed Prevention Roller is pressed against the Separation Roller, and this results in a separating force being applied to the document, which will separate the layers, resulting in damage to the document.
6.3. Paper Feed Operation 1. When the Paper Feed Motor rotates the Paper Feed Motor in the paper feed direction, Paper Feed Roller will go down until the roller is in contact with, and then rotate in the paper feed direction. (Arrows 1 →2 → 3 → 4) At this time, Separation Roller will also rotate in the paper feed direction.
Page 31
2. On the other hand, when the Paper Feed Motor rotates the Paper Feed Motor in the reverse direction of paper feed, the Paper Feed Roller will rise and won't rotate. (Arrows 1→ 2→ 3) At this time, Separation Roller will also rotate in the paper feed direction. (Arrows 1→ 2→ 3)
6.4. Glass Cleaning Mechanism (Auto) After turning on the scanner or finishing scanning, this scanner will rotate the Conveyor Motor in the reverse direction of paper-feed to rotate the Reference Plates (F) and (B). This performance will enable the brush attached on the plates clean the glass surfaces. 6.5.

11 CIRCUIT DESCRIPTION 11.1. Block Diagram-1 (Image Processing) On this system, the CPU (IC0006) controls the operation of the USB Controller (IC0010), the Gate Arrays (ASICs: IC0035 and IC0038), the Sensors (Paper Sensor and others), and the Motors (Paper Feed, Conveyor, DFP Pressure). Motor pulse signals for conveying paper (Conveyor Motor) are provided from the Gate Array (ASIC: IC0035).
