There are a variety of causes behind a malfunctioning scanner, and each requires its own troubleshooting steps in order to properly diagnose and fix the issue. Depending on the type of scanner, some of these steps may apply while others may not. Here is a comprehensive guide to addressing common issues with both flatbed and document scanners.
Flatbed scanners
1. Check your power source. Make sure the scanner is plugged into a working power outlet and has the correct voltage. Also check the power cord for any physical damage.
2. Check the USB cable. If your scanner is connected via a USB port, ensure that the cable is securely plugged into both the scanner and the computer. Additionally, try using a different USB port or a different cable and see if it helps.
3. Update any necessary drivers. Outdated drivers for the scanner can cause it to malfunction. Look for updated drivers on your scanner’s product page or manufacturer website.
4. Ensure that the scanner lid is closed properly. Some scanners may have problems working correctly if the lid is open or not properly aligned.
Document scanners
1. Check the paper feed. Make sure the paper is loaded correctly into the feed tray and that the tray is properly aligned with the scanner. Also ensure that no foreign objects are obstructing the paper path.
2. Clean the scanner. Using a soft cloth, wipe down the inside of the document feeder, including the rollers, sensors, and any other areas where dust or debris may have accumulated.
3. Check the included software. Make sure that the included software is installed on the computer and up to date. If necessary, download and install the latest version from the manufacturer’s website.
4. Calibrate the scanner. This step is only applicable to scanners that are equipped with automatic calibration technology. Use the included software to perform a calibration scan, which should resolve any scanning issues.
If you have followed all of the troubleshooting steps above and the scanner still is not working properly, it may be time to contact the scanner’s manufacturer for assistance.
