Salvaging HP Photosmart All-In-One C4580 electronic parts

Throughout my novice experience i wanted to setup Continuous Ink Supply System (CISS) on my photosmart C4580 printer, but in the end it turns out to be the wrong thing to do with this printer. The two major problems with the CISS was the smudging effect when printing and at the same time flooding the whole printers with the ink. Eventually i didn't even realized the flooding was so bad all over the internal structure of the printer and damaged the electronic components. In the end after i decided to salvage the valuable electronic components and parts from the printer.

The HP printer built is really easy to open unlike Fuji Xerox but for careful works it took an hour to open up the whole thing. The tool required was only 2 head of torx screwdrivers and below are the items I've fond inside the printer.

1. White board from the scanner cover
2. Fine square glass of the scanner
3. 2 DC motors
4. Steel rods from the feeder
5. Control panel electronic board with LCD and where there are quite a number of electronic switches on it
6. Photo interrupter sensors
7. Cartridge circuit board controller
8. Network card electronic board
9. Scanner light and DC motor
10. Lot of screws and Springs

Overall the square glass, DC motors, (802.11g WiFi Card 1150-7931 WN4300A), and the photo interrupter sensors were the most important part as they can be used for hobby projects.
