Salvagable printer & scanner parts for 3D printers.

I see so many printers and scanners on the curb that I figured it might be useful to try to recycle some of the components.

I've been compiling a list of desktop printers and scanners I come across that have parts worth salvaging for building 3D printers and desktop CNC machines:  Here are models I've found so far:

Printers:
Epson stylus: 4xx, 6xx, 7xx, x60, C86, CX3200, Color 777

Scanners:
Epson perfection 2400 photo, Microtek Scanmaker 5600, CanoScan 9900F

Noteworthy are the NEMA17 stepper motors, many of which already have pulleys and timing belts.  Perfect for 3D printer X and Y axes.  There's also usually always at least one usable precision-ground rod and a set of brass bushings for linear motion.

Often you can peek inside and see if the printer is worth snatching for this purpose.  If you can't see the motor directly (like in the scanner pictured above) you can still usually spot a NEMA17 by looking where the motor is mounted for four screws spaced about 30mm apart from one another.
