Epson B12B819691 Paper Alignment Plate for DS-870 Scanner
Overview
The Epson B12B819691 is the factory-replacement paper alignment plate for the DS-870 document scanner. The alignment plate guides media through the feed path, keeping documents registered accurately during high-volume batch scanning — a worn or damaged plate leads to skewed pages, misfeeds, and OCR errors that compound across large document runs. Replacing it with the correct OEM component restores the feed path geometry the DS-870 was calibrated around, avoiding the throughput loss and re-scan cycles that come with a degraded original.
Compatibility
The B12B819691 is designed specifically for the Epson DS-870 document scanner. It is not a universal alignment plate — confirm your scanner model before ordering. If you are maintaining a fleet of Epson departmental scanners, verify the exact model designation on the unit's label; the DS-870 is a distinct platform from the DS-860 and DS-970, and alignment plates are not interchangeable across those families.
Installation Notes
Installation is a field-serviceable procedure on the DS-870. No soldering or special tooling is required, but consult the DS-870 service documentation for the correct disassembly sequence before removing the existing plate — improper removal can stress the feed assembly. Ensure the scanner is powered off and unplugged before beginning. Seat the replacement plate fully before reassembling; a partially seated plate will reproduce the same misfeed symptoms as a worn one.
