What It Is: The external Power Supply Adapter (AC Adapter) - the power brick that plugs into the wall and supplies DC power to the scanner. A faulty or underpowered adapter causes the scanner to fail to power on, disconnect mid-scan, or show a power-related error.
Part Number: 0957-2271 / 0957-2259 / 0957-2479 (32V @ 1560mA) - HP's own official external-adapter numbering scheme.
Condition: New Original - factory new, tested and working.
Warranty: 30-Day Replacement Warranty from date of delivery.

Note: The source listing's compatible-model list also includes several HP OfficeJet/OfficeJet Pro inkjet printers (7000 Wide Format, 7500A, 7510A, 8000, 8210, 8600 Plus, 8610, 8700, 8710) alongside the scanners above - HP is known to share this same external 32V adapter across many different device lines, so this breadth is plausible rather than a data error, but it's worth confirming the exact printer model against this adapter's physical connector before shipping.
