The Epson B12B813561 is a roller assembly kit designed to maintain the efficiency of your document scanner. It serves as a direct replacement for the feed rollers in the WorkForce DS-510, DS-510N, DS-520, DS-520N, and DS-560 models, ensuring that pages move smoothly through the device without jamming. These components are built to handle a high volume of work, with a rated replacement interval of 100,000 sheets. Because the rollers are user-replaceable, you can install the new kit yourself without needing professional technical service, which helps minimize downtime in a busy office environment.
