Overview

The Epson B12B813421 Scanner Maintenance Kit contains the two most critical wear components in any document scanner: the paper feed roller and the separation pad. Over time and use, these parts gradually lose their grip and texture, leading to unreliable paper pickup, multi-sheet feeds, and frustrating paper jams. This genuine Epson kit provides factory-specification replacements that restore your scanner's paper handling to like-new performance.

Epson rates the replacement interval at every 100,000 sheets, making this a relatively infrequent maintenance task for most users. The installation is designed to be performed by the end user without any special tools — the old roller and pad pop out and the new ones snap into place in a matter of minutes. At just 2.15 ounces and measuring 4.25 x 2.75 x 2.25 inches, the kit is small enough to keep as a spare on hand so you can minimize downtime when replacement is eventually needed. For offices and workgroups that rely on consistent scanning throughput, keeping a spare maintenance kit available is a simple way to avoid unexpected productivity interruptions.

Frequently Asked Questions
