If dirt still remains, try using the Cleaning sheet (wet) supplied with your product. Remove the Cleaning sheet (wet) from its bag, unfold it, and then follow the same steps as when cleaning the scanner using the Cleaning sheet (dry). The Cleaning sheet (wet) can only be used once. If you cannot clean the scanner using the Cleaning sheet (wet), contact your Epson dealer. Do not disassemble your scanner. The best before date for the Cleaning sheet (wet) is approximately two years from the production date printed on the package.
The Cleaning sheet (dry) can be used more than once. However, if it begins to lose its effect, purchase a new Cleaning sheet (dry).
The Cleaning sheet (dry), Cleaning sheet (wet), and Calibration sheet are available as a Maintenance Sheet (Model number B12B818291) from your nearest Epson store.
