Clean the separation pad The separation pad wears out with normal use. Using poor-quality paper can cause the separation pad to wear out more frequently. If the product regularly pulls multiple sheets of paper at a time, you might need to clean or replace the separation pad. WARNING! Before cleaning the separation pad, turn the product off, disconnect the power cord from the wall outlet, and then wait for the product to cool. 1. Disconnect the power cord from the product. 2. Remove the paper and close the input tray. Set the product on its side. CAUTION: The scanner assembly opens when the product is on its side. 3. At the bottom of the product, unscrew the two screws holding the separation pad in place. ENWW Clean the product 149
