Write problem/project Goal
''Remove as much of the printer's parts while it still functions. Most of the moving parts should be displayed''

My First Task
Remove as much parts as possible while still having the printer functioning.

Summary of actual work over first weekend
The external housing for the printer was removed.

Week1 Narrative
'' I removed some of the external parts. The printer was also tested to make sure that it still functioned. I was able to run a paper through the printer with the external parts off.''

My Second Task
Remove as much parts as possible

Summary of actual work over second weekend
The printer was completely disassembled and the printer was not functioning.

Week2 Narrative
''The Printers was completely disassembled. I ditachteched the circuit board and disconnected all the wires. The motor was also removed and main turning gear that was attached to the motor also was removed by one of the group members and he also Disassembled them.. The printer was not functioning at this stage. ''

My Third task
Get the printer working again and open the laser part on the printer and replacing the laser with a LED so the path the laser takes can be traced .

Summary of actual work over third weekend
'' Most of the work done was on getting the printer to work again. The laser was removed but this was not dealt with that much. ''

Week3 Narrative
''I reconnected the circuit board to the printer. There was no life in the printer initially so the circuit board hard to be removed. It was then discovered that one of the wired from the circuit board to the power supply was disconnected. One of the group member and i then soldered this wire. The circuit board was then reconnected and all the wires connected and tested again. This time the display had life and when the open/close switch and the switch that senses the presence of the cartridge was held down the motor started running and all the turning gear started turning. I also opened the laser component and the laser located and removed. ''

My Fourth task
'' Replace the laser diode with an LED so the path the laser takes can be traced and mount the printer on a plywood. ''

Summary of actual work over fourth weekend
The Laser diode was removed and replaced with an LED and the printer mounted on a plywood

Week4 Narrative
''I got a LED from the LED box but this LED was not bright enough to trace the path of the laser so a brighter LED was taken from one of those LED's that glows under cars. I had to solder wires on to the terminals because they were to short to be used. This was a tricky task because they were so short that the LED itself could have been damaged from the heat of the soldering iron. The LED was taped so that only a beam of light would pass though. The path was much more recognizable when this was done. THe Printer was trimmed of the parts that were covering most of the moving parts by some of the other group members. The printer was then mounted on a plywood and a switched attached.''
