4.2. Included Accessories Confirm that the following items are included with the scanner. Note • It is highly recommended to keep the original carton and all packing materials. They are necessarywhen repacking.
4.3. Installing Double-feed Prevention Roller 1. Remove all packing tape. 2. Push the ADF Door Release (1) upwards, and open the ADF door (2). 3. Use the indents (1) to pull the double feed prevention roller cover towards you to open it. 4.
Page 14
Note After you install the Double-feed Prevention Roller, make sure that the shaft is inserted into the tab, and that the shaft will not rotate or move. If the roller is not installed correctly, it may cause double feeding or a paper jam. 5.
4.4. When Scanning Documents of Different Sizes Together Note See the following conditions for scanning documents of different sizes together. • Document thickness The ratio of the thickness between the thickest paper and thinnest paper must be less than 1.5. •...
Page 16
3. Completely spread apart the Document Guides (1). 4. Align the documents along one side of the guides. 5. Slide the Document Guides to align the document position so that the center of the smallest sheet can be fed into the center of the paper slot.
4.5. Connecting the Scanner to a Personal Computer Connect the accessories’ Power Cord and USB cable to the back of the unit. Caution: 1. Only use the Power Cord and USB Cable enclosed in this scanner. 2. Be sure to connect the scanner directly to the USB interface port on the PC. We cannot guarantee that the scanner will work properly if it is connected to a USB hub.
4.6. System Requirements When using the scanner, the minimum system requirements are as follows. Computer ® PC/AT or compatible machine with a CD-ROM drive ® ™ Intel Core 2 Duo, 1.8 GHz or higher Operating System ® ® ® ® Windows XP (64 bit Edition is not supported.), Windows Vista , Windows...
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 Hopper rises until hopper position sensor detects the documents. 2. Then conveyor Motor will be driven to rotate the three Drive Rollers (Drive Roller 1 to 3) and Exit Roller, and the Paper Feed Motor will be driven to rotate the Paper Feed Roller and the Separation Roller in the feed direction.
Page 25
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 28
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 platen Motor to rotate the Reference Plates (F) and (B). This performance will enable the brush attached on the plates clean the glass surfaces. 6.5.
6.6. Mechanical Deskew Mechanism (KV-S5076H only) Deskew Correction is performed by the Drive Roller 1. 1.Detect the Skew of the document. 2.Adjust the skewed document direction by different Roller rotation speed between Left and Right Roller. (Deskew) * Only Right Drive Roller can change its speed.
Page 31
Drive Roller 1 R accelerate the rotation speed. * In case of opposite skew, Drive Feed Roller 1 R decelerate the rotation speed. Skew adjustment is completed till the document reaches Drive Roller 2. * After the document reaches Drive Roller 2. both Driver Rollers rotate at the same speed.

11 CIRCUIT DESCRIPTION 11.1. Block Diagram-1 (Image Processing) On this system, the CPU (IC0006) controls operation of the ASICs (IC0035,IC0038), FPGA (IC0030,IC0031),the Sensors (Paper Sensor and others), and the Motors (Paper Feed and others). Motor pulse signals for conveying paper (Conveyor Motor) are provided from the ASIC (IC0035). On the other hand, motor pulse signals for the other motors are provided from the CPU (IC0006) and FPGA (IC0030).
