The Epson Roller Assembly Kit B12B819381 is a replacement maintenance part for the WorkForce DS-410 scanner. It renews the scanner’s pickup and separation rollers, which move and separate originals during feeding.
Epson gives the kit a 100,000-scan service-cycle guide, based on consecutive scans with Epson test originals. The actual replacement interval can vary with the paper being scanned, including dusty or rough-surfaced stock.
After installing the kit, reset its scan count in Epson Scan 2 Utility so the scanner’s maintenance counter reflects the replacement.
