The Epson DS-530 Carrier Sheet (Product Code B12B819051) is a crucial accessory for the Epson WorkForce DS-530 and several other compatible sheet-fed scanners (like the ES-400, ES-500W, DS-570W, etc.).
 
Scanning Fragile or Irregular Media: It allows you to scan documents that are too delicate or have an irregular shape, which would otherwise be damaged or cause jams if fed directly through the scanner's rollers.
The carrier sheet acts as a guide, and the scanner's software (A3 stitching feature in Epson Scan/Document Capture Pro) can automatically combine the two halves of the scan back into a single A3 (Ledger) image
