Clean inside the product and clean the rollers. If the rollers were previously removed for cleaning,
make sure they were properly reinstalled.
Check the number of sheets scanned by the pickup roller. If the number of scans exceeds the
pickup roller's service life (50,000 sheets), replace the roller assembly kit with a new one. Even if the
number of scans does not exceed the pickup roller's service life, we recommend replacing the roller
assembly kit with a new one if the surface of the roller is worn out.
Note: You can check the number of sheets scanned by the pickup roller in the Epson Scan 2 Utility.
Start the Epson Scan 2 Utility, click the Counter tab, and then check the Number of Scans under
Roller Assembly Kit.
If multiple feed errors occur frequently, it is possible that dust or dirt that has accumulated around
the ultrasonic sensors is being mistakenly detected as a multiple feed error. If dust has accumulated
around the ultrasonic sensors, clean the ultrasonic sensors.
Use Automatic Feeding Mode in Epson Scan 2 and scan originals one at a time.
If you see a double feed error in the Epson Scan 2 window or the Document Capture Pro window
(Windows only), start Epson Scan 2, select the Main Settings tab, select the Detect Double Feed
setting, and select Off.
Note: On a Mac, only Epson Scan 2 displays double feed errors. Document Capture for Mac does
not include this setting.
