PA03575-D201 Fujitsu FI-680PRF ImprinterThe imprinter option enables users to print information on original documents for document management purposes. While the FI 680PRF (post imprinter) prints information on the front of documents, the FI 680PRB (post imprinter) prints information on the reverse side of documents after they have been scanned. Although both the FI 680PRF and the FI 680PRB may be attached to the same scanner unit, both imprinters cannot be used simultaneously.
