Symptom The image scanned is too light or too dark. Lines on the document are blurred. (Example: Ruled lines on a table cannot be seen.) Scanning speed is very slow. Multi-feeds (*4) occur frequently. Paper is not fed (stops midway). The scanner is not recognized even if ScanSnap Manager is installed. The file size of a scanned black & white image is the same as that of a scanned color document image. Images on the back of pages, which are printed-through, are overlaid on the scanned image when scanning a two-sided document. (This is called "noise" of the back side image). Check This Item Is the "Brightness (Black and White scanning only)" setting on [Option] of the [Scanning] tab set to extremely Light or Dark? Are you scanning in color mode, documents including handwritten or typed text, tables or frames with ruled lines? Does your PC satisfy the recommended system requirements? Is the USB 1.1 connected? Note: When using an USB1.1 interface, the data transfer rate may be slower due to large data sizes. Is the Pad ASSY dirty? Is the Pad ASSY worn out? Is the document stack thicker than 5 mm? Is the Pick roller dirty? Is the Pick roller worn out? Are there any debris on the document feeding path? Do the loaded documents satisfy the conditions described in section 3.2 on the Operator's Guide? If not, they might not pass smoothly through the ADF. Did you connect the scanner to your PC before installing ScanSnap Manager? Is the scanner registered as "Other device" in the "Device Manager"? Is the B&W document scanned in the color mode? Is the "Setting for text only document." checkbox cleared in the "Read mode option" dialog box ([Option] on the [Scanning] tab of the "ScanSnap Manager - Scan and Save Settings" dialog box)? Remedy Adjust "Brightness" at [Scanning] - [Option] in the "ScanSnap Manager - Scan and Save Settings" dialog box. The color mode is used for capturing colored images like photos in high quality. For other documents including textual content, select the check box for [Setting for text only document] at [Scanning] - [Option] in the "Scan and Save Settings" window. If it does not improve even after you have tried this method, change "Image quality..." setting. Check the system requirements in the ScanSnap S510 Operator's Manual. Scanning speed will be slower whenever the CPU and memory requirements are not met. If this is the case, at [Scanning] - [Option] in the "ScanSnap Manager - Scan and Save Settings" dialog box, clear the check boxes of the following to increase the scanning speed. - Correct skewed character strings automatically - Allow automatic image rotation If your PC has an USB 2.0 port, connect the scanner to this port. (If using a USB hub, it must also support USB 2.0 interfaces.) (*3) Clean the Pad ASSY following the instructions in "5.3. Cleaning Inside of the scanner". Replace the Pad ASSY following the instructions in "6.2. Replacing the Pad ASSY". Reduce the number of sheets of the document stack to 5 mm thickness or less. Clean the Pick roller following the instructions in "5.3. Cleaning Inside of the scanner". Replace the Pick roller following the instructions in "6.3. Replacing the Pick Roller". Remove any debris from the document feeding path. Refer to "4.2. Clearing Paper Jams". Try the following: ・Slightly push through with your finger the first sheet of the documents at the start of scanning. ・Change the insertion direction of the document. On the [Start] menu, select [Control panel] [System] [Hardware] [Device Manager]. Delete the device name such as USB device (differs with the OS) under "Other Device" selection in the [Device Manager] and restart your PC. Select "B&W" from the [Color mode] drop-down list on the [Scanning] tab in the "ScanSnap Manager - Scan and Save Settings" dialog box. Mark the "Setting for text only document." checkbox. (Available only in color mode) Marking it makes characters, lines, and contrasts sharper and clearer, and the removes the noise of the backside image. Note that you can also use this mode for documents including photos and illustrations. Even if this mode is used, contrasts and colors might be affected. ScanSnap S510 Getting Started | 17
