The Readme file contains additional information that may help you diagnoseproblems with the scanner.If you try the troubleshooting procedures described in this section and in the Readme file, and thescanner still has problems, visit our web site at www.xeroxscanners.com for additional technicalinformation.Problem: The scanner won’t scan. What’s wrong?Check for one of these possible causes:• Are the cables loose or not plugged in securely? Inspect the cable connections. Make sure thecables are plugged in securely.• Is the scanner’s status light on? Turn on the scanner’s power. If the status light doesn’t come on,plug the power supply into another electrical outlet.• Did you restart the computer after installing the software? If you didn’t restart the computer, itmay not have loaded all of the software files. Try restarting your computer.• Did you plug the scanner into a USB hub? If you’re using a USB hub to connect the scanner, thehub must have its own power supply. If the hub does not have its own power supply, plug thescanner into a USB port on the computer.• Did you select another TWAIN source for acquiring images? If you use multiple TWAIN deviceswith your computer, you may have selected another source for images. Start the PaperPortsoftware and click the Scan icon, then make sure DocuMate 3115 is selected as the scanner.Problem: The installation will not complete successfully. If installation finishes, the scanner’sOne Touch 4.0 options do not seem to work properly.A likely cause is that some driver programs are already installed on your computer for another scanner.Or you previously had another Visioneer scanner and that driver program is still on your computer.They are interfering with the installation and One Touch options, and you need to remove those otherdrivers and re-install your DocuMate 3115 scanner. Please see the documentation that you receivedwith the other scanner for the steps to remove its driver programs.Problem: My computer keeps giving me out of hard drive space error messages.The minimum requirement of 350MB free hard drive space is for the installation of the software andbasic, low resolution, scanning. High resolution scans result in files that can be over 1 gigabyte in size.Free up some space on your hard drive for the software to be able to save the scanned images.Problem: With AutoCrop to Original selected, sometimes I get blank pages, or pages with lines.The pages were probably scanned in crooked, or skewed. To use AutoCrop to Original, the pages mustbe scanned in straight. Adjust the paper guides on the scanner so pages feed in straight.
