User:Ainmed19/HCC Group 4

Objective
Our group was assigned the task of taking apart a printer in order to understand and apply the principles of documentation into our engineering notebooks. Certain parts were salvaged in order to be used in future projects.

Printer

 * Xerox WorkCentre XD130df
 * PC: RW9 Manufactured SOCC 2000 April 009909
 * 120 V N : 60Hz
 * 9.5A 1000 W





Disassembling

 * Took apart the ink cartridges first. They were easy to remove, so we took them out. We never opened the ink cartridge itself as it was recommend that we do so with gloves, safety masks over our mouths.


 * We also found a green, metallic cylinder that is shot at by the laser in the printer.


 * We also found two more rolling pins that seemed to be paper feeders. A rubber one and a plastic one that contained a heating element and had a heat tempered black paint inside.




 * We began to remove the scanning glass that lies at the top of the printer. After removing the glass, there was nothing of importance underneath except a small magnifying lens. We salvaged the lens for a future project, we assumed the lens was used to focus the laser beam for the printer.


 * We then proceeded to remove the whole back piece. We discovered the circuit/operating board. The large board contained so many usable part that we just kept the whole thing intact. We found a DC motor, Stepper motor, resistors, micro-controllers, and capacitors.




 * We then took apart the paper feeding components and trays that had a spring like system to them that we decided to salvage for other projects. The insides of the feeding components revealed gears that we also kept for the future.


 * We followed the wires from the big circuit board and located the main power supply. This was a surplus of usable materials and parts, like capacitors, so we kept the entire power supply board.


 * We then found a digital display that had many usable pieces like LED's and a programmable 7-segment display. And threw away all excess material concluding the printer project
