1. Check the paper. Ensure that it is straight and not stuck to the scanner bed. Check for any obstructions in the paper path, such as staples or loose bits of paper.
2. Make sure that the scanner driver is up to date and installed properly. This can be done by downloading the latest driver from the manufacturer’s website and installing it.
3. Restart the scanner and computer to ensure that the two are communicating properly.
4. Replace the scanner lid if it is damaged or broken. This could be causing a jam.
5. Run some cleaning sheets or wipes across the scanner bed, glass plate, and paper feed tray. This can help remove any dust or debris that may be causing the scanner to stop in the middle of a scan.
6. Run a calibration test to make sure that the scanner is calibrated correctly. This can be done in the settings menu of the scanner.
7. Make sure the power cord is plugged in correctly. If it is loose, or not plugged in tightly, it could cause the scanner to stop in the middle of a scan.
8. Consider resetting the scanner to its factory settings. This can often be done in the settings menu of the scanner.
9. Contact the manufacturer if all else fails. They may be able to provide further advice on how to troubleshoot the issue.
