Scan Module for HP Laserjet 1100

Turn your Laserjet 1100 into a scanner/copier

You could buy a new one, here, for $236.25.  Or, you could buy this excellent condition, tested and working unit, for much less.

(It's a good, clean, pretty low use unit.  Note that the little plastic prop that holds the feeding sheet is not included, as shown in the photos but this does not affect functionality.)

Official blurb:
Turn your HP LaserJet 1100 into a multifunction device with the Copy/Scan accessory.  Made expressly for this laser printer, the accessory adds copying and scanning capabilities to the printer.  The JetPath technology from Hewlett-Packard eliminates the speed and copy quality degradations found in many multifunction devices.  This technology is code designed into the firmware, hardware and software to allow the printer to take on additional capabilities and improve functionality.  The copier function lets users make copies with or without the PC on at speeds of up to 8 ppm at 600 dpi resolution.  Copier settings include Reduce/Enlarge and Multi-copy adjustable from PC, and push-button (no PC required).  The scan function allows users to scan hard-copy documents into electronic images for editing, filing, and sending by e-mail and PC fax.  Scan documents at 300 dpi resolution, 600 dpi enhanced in grayscale.
