How to Troubleshoot the Scanner on an All-in-One Printer. Troubleshooting the scanner of an all-in-one printer is a straightforward process of elimination. You begin at the most basic level, striking off those issues that are not the problem and work your way up the ladder of complexity until you have a working scanner. Follow these steps to troubleshoot the scanner on an all-in-one printer:
What to Do
Check the power. Almost everyone has missed this easy fix at least once. Make sure all power switches are on, all cords are plugged in and any indicator lights are showing green.

Eliminate the chance for operator error by refreshing your memory on the operating instructions. If you discover that you have been missing a step in the scanning process, highlight the relevant step in the operating manual and try to scan again.
Verify the correct positioning of the document you want to scan, which is face down on the scanner bed glass. Spot clean the glass if necessary with a damp cloth.
Double-check your scan optimization settings. Some printers allow you to refine their settings for print only, image only or mixed documents. Make sure you have the right one selected.
Make sure you have the right computer destination selected in a network. If you are not in a network, examine the cables that connect your all-in-one printer to your computer.
Keep the device's task manager on while scanning. Some all-in-one printers need their task manager in the toolbar to function properly.
