Maintenance Xerox® DocuMate® 4760 User Guide37 Replacing the Feed Roller The roller will wear out and is designed to be a user-replaceable part. A worn roller can cause documents to feed in skewed at an angle, or multiple pages to feed at the same time. Before replacing the roller you should clean it as excessive dust on the roller will make it appear worn and smooth. You cannot properly diagnose a worn roller until you have cleaned it. You should generally replace the roller every 160,000 to 200,000 scans. Replacement parts can be purchased from the Parts & Accessories page for your scanner at www.xeroxscanners.com . The feed roller module is located in the body of the scanner. You will need a flat head and a Phillips head screw driver to replace the feed roller. 1. Open the scanner. 2. Using a Phillips head screw driver, remove the screws holding the roller cover in place. Set the screws aside, you will need them to reattach the roller cover. WARNING: these parts are small and pose a choking hazard.

Xerox® DocuMate® 4760 Maintenance 42User Guide Troubleshooting 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 the cables 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. If you are using a UPS battery back-up or power strip, try plugging the scanner directly to a wall outlet. •Did you restart the computer and scanner? If the scanner gets a paper jam, or looses connection because of an error, try restarting your computer and power cycling the scanner. •Did you plug the scanner into a USB hub? If you’re using a USB hub to connect the scanner try plugging the scanner’s USB cable directly to the back of the computer. It is not recommended that you use the scanner with a USB hub, if you are using a hub, the hub must have its own power supply. •Is the USB cable 6’ or less? If you are using a USB cable that is longer than 6’ you may lose connection to the scanner. The recommended USB cable length is 6’ or less, the USB cable provided with your scanner is within this range. •Did you select another image source in the scanning software? If you use multiple imaging devices with your computer, such as a camera, all-in-one printer, or another scanner, you may have selected another source for images. Make sure Xerox ® DocuMate® 4760 is selected as the scanner. Problem: Why does my scanner not function after performing a system restore on Windows? The system restore process may have corrupted some of the driver components. It is recommended that you reinstall your scanner driver. Please refer to “Uninstalling Your Scanner” on page 45 for installation instructions. Problem: Why won’t my scanner buttons work after scanning with Windows Image Acquisition (WIA)? After performing a scan using the WIA interface you must close the application you were using before scanning with the buttons on the scanner. This does not occur when scanning using the TWAIN or ISIS interface. Problem: Why won’t my scanner work after the computer has been sitting idle for several hours? To resolve the problem, simply turn off the scanner power then turn it back on again. This may occur after Windows goes into power saving mode to “hibernate” the computer into a low power state. When you move your mouse or type on the keyboard it “wakes” the computer back up and restores full power to the system. This power fluctuation during the computer’s hibernating period may sometimes cause the scanner to lose communication to the computer.
Maintenance Xerox® DocuMate® 4760 User Guide43 Problem: The installation will not complete successfully. If installation finishes, the scanner’s OneTouch options do not seem to work properly. A likely cause is that some driver programs are already installed on your computer for another scanner. They may be interfering with the installation and OneTouch options, and you need to remove those other drivers and re-install your Xerox ® scanner. You can remove these programs from the Windows Control Panel. Please refer to the user manual provided with your other scanner hardware for instructions about removing the driver and software for that unit. Problem: My computer keeps giving me out of hard drive space error messages. The minimum requirement of free hard drive space is for the installation of the scanner driver and basic, 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: The paper jams the ADF. To reduce the number of paper jams, smooth and straighten the paper before scanning, and adjust the guides to the paper size. Paper fed into the ADF at an angle can cause the feed mechanism to jam. If paper jams are occurring more frequently, try cleaning the roller with a soft cloth dampened with Isopropyl rubbing alcohol. Excessive dust on the roller can make it appear worn and will cause issues feeding paper. See “Cleaning Inside the Automatic Document Feeder” on page 33 for cleaning instructions. Problem: The ADF won’t feed pages properly. A dirty or worn roller can cause documents to feed in skewed at an angle, or multiple pages to feed at the same time. First, try cleaning the rollers as described in “Cleaning Inside the Automatic Document Feeder” on page 33. If the problem persists, the separation and/or feed rollers may need to be replaced. Please see “Replacing the Separation Roller” on page 34 and “Replacing the Feed Roller” on page 37. Problem: If the USB cable is disconnected during a scan, the scanner does not reconnect when the USB cable is plugged back in. Unplug the power cable from the scanner, and then plug it back in. If the scanner does not reconnect: 1. Unplug the power cable from the scanner. 2. Restart your computer. 3. After the restart is complete, plug the power cable back in. Problem: The scanner reports a Double Feed error when there is only one page in the scanner. Try cleaning the double feed detection sensor. Dust on the sensor may prevent the sensor from working properly.
