Problem 12 The document was fed but no scanned images were saved. Solutions If [Scanning Side] of the scanner driver is set to [Skip blank page], pages with few black portions may be unintentionally deleted (skipped). Select another scanning mode such as simplex or duplex, or reduce the ratio for black dots. For the solution for missing pages caused by double feeding, see "Problem 9 Pages become jammed or double fed." Problem 13 Cannot save the scanned images of multiple pages as one file in JPEG format or BMP format. Solutions In JPEG format and BMP format, scanned images of multiple pages cannot be saved as one file. Save them in TIFF format (or PDF format). Problem 14 Cannot use Select Scan Job. Solutions If both Scan First and Select Scan Job are assigned to the Start button, priority is given to Scan First. If you want to assign Select Scan Job, clear the [Assign scanner Start button to Scan First] check box in the main screen. Problem 15 The scanner makes unusual noise while feeding documents. Solutions The paper quality of some documents can result in unusual noises, but this does not indicate a malfunction. Software Troubleshooting Scanning takes a long time. (1) End any other running applications. (2) Scanning may become slow if there is insufficient system memory because applications (anti-virus software, etc.) are resident in the system. Close such resident applications, and then try scanning again. (3) When insufficient hard disk space is available, the scanner may be unable to create the necessary temporary files (files for temporarily saving scanning data) during scanning. Delete any unnecessary data on the hard disk to free up more space. (4) Scanning is slow if the computer's USB port is not Hi-Speed USB 2.0 compliant. (5) If you are using a commercially available USB cable that is not HiSpeed USB 2.0 compliant, replace it with the supplied USB cable (Hi-Speed USB 2.0 compliant). (6) When the scanner and computer are connected via a USB hub that is not Hi-Speed USB 2.0 compliant, remove the hub and directly connect the scanner and computer. The saved scanned images cannot be opened in applications. (1) To open scanned images saved as multi-page TIFF files, an application that supports this format is required. (2) Even if scanned images are saved as TIFF files that are not multipage, some applications will not be able to open them if the TIFF files are compressed. This is the case with applications that do not support the compression format of TIFF files created with CaptureOnTouch. If files cannot be opened, select None as the image file compression format before scanning. 63
