Abstract: A scanner disposed within a portable copier includes a scan carriage, a document indexer for transporting a document along a document transport path, a copy sheet indexer for transporting a copy sheet along a copy sheet transport path, and a printhead and ink supply cartridge, preferably a ribbon cartridge, supported by the scan carriage. The document and copy sheet paths are disposed on opposite sides of the ribbon cartridge, allowing removal and replacement of the ribbon cartridge on the scan carriage without disturbing the position of either the copy sheet or the document. Separate motors drive the document and copy sheet indexers, so that the copy sheet may be ejected from the device without advancing the document and without moving the scan carriage.
