If your scanner is displaying a “no paper detected” error, there are several possible steps you can take to troubleshoot and resolve the issue.
1. Check whether the document you’re trying to scan is properly inserted into the document feeder. Make sure the document is face-down on the scanner bed, with the appropriate side facing up. Also make sure the paper is not bunched up in any way that would hinder the scanner from detecting it.
2. Inspect the scanner roller pad to ensure it isn’t dirty or damaged. If it appears to be dirty, lightly dampen a lint-free cloth with isopropyl alcohol and clean the rollers. Avoid using paper towels or abrasive cleaning agents as they can damage the rollers.
3. If the rollers are particularly dirty or worn out, consider replacing them. You can purchase a roller kit at most electronics stores that includes replacement rollers and other scanning components.
4. Check to make sure the paper size selected in the software matches the size of the document you’re trying to scan. If not, try changing the paper size setting to match.
5. Clean the document pick-up area of the scanner. Use compressed air and a lint-free cloth to clear away any dust or debris that may be preventing the scanner from correctly detecting the paper.
6. If the error persists, try turning off the scanner and restarting it. This can often help to reset any errant settings that may be causing the problem.
7. If none of the above steps resolves the issue, it’s possible the scanner’s optical sensors are malfunctioning and need to be replaced. If the scanner is still under warranty, contact the manufacturer for technical support; otherwise, you can hire a technician to replace the faulty components.
