7.2 Troubleshooting Checklist Symptom 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 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 Paper Size of Documents to be Scanned" (page 46)? 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)? Resolution Clean the Pick roller by following the instructions in "8.3 Cleaning the Inside of the Scanner" (page 232). Replace the Pick roller by following the instructions in "9.3 Replacing the Pick Roller" (page 243). Remove any debris from the document feeding path. (Refer to "7.1 Clearing Document Jams" (page 218). 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 removes the noise of the back side image. Note that you can also use this mode for documents including photos and illustrations. Even if this mode is used, the contrasts and colors might be affected. 7 Troubleshooting ScanSnap S510 Operator's Guide 223
