Troubleshooting Scanner Problems

1
Download the proper drivers. Input your scanner brand and model into a search engine along with "driver download". Be sure to use the official company website for your scanner.
- After installing your scanner's drivers, restart your computer.
- MacOS should automatically install the latest scanner software. If it doesn't, you'll need to update your software manually.
2
Restart your computer. In some cases, your computer may need a restart to function properly. Do this after installing any new programs or drivers.
- On Windows, select Start → Power → Restart.
- On Mac, select the Apple menu → Restart.
3
Restart your scanner. Use the Power button on your scanner to turn off the device. Unplug it from the power for a few minutes, then plug it back in.
- Refrain from turning off the scanner by unplugging the scanner if you have a Power button. This could interrupt scans in progress and cause your device to slow down.
4
Connect your scanner via ethernet. Your scanner may have trouble connecting to your Wi-Fi network. Connecting your scanner to your computer with an ethernet cable can help your computer recognize the device.
5
Make sure the scanner is within range. If your scanner is too far from your computer or if its signal is blocked, your computer won't be able to recognize it. Try to set up your scanner next to your computer.
6
Check firewall and antivirus settings. Your scanner needs permission to communicate with your computer. Be sure your scanner is an allowed program in your firewall and antivirus settings.
7
Purchase a new scanner. If you're trying to connect an old scanner with a new computer, the software may no longer be compatible. In this case, you'll need to buy a new scanner.
