Week0 narative
''i researched about the hp printer 940c. i looked up some of the essential part needed for the printer to work. i also looked up a website http://computer.howstuffworks.com/inkjet-printer2.htm in which they list some of the important commponents. i also watched a video which explains how a inkjet printer works http://www.youtube.com/watch?v=D1ks3xK2f_0.''

Week1 Narrative
''this week i worked on finishing the printer project. first i opened up the outer body of the printer and identified its important components and decided what could possibly be taken out of it while still making sure that the printer would still work.. i saw that the most important components were the two motors which were used for moving the print head which held the ink cartridges and to pull paper in, the circuit, the rollers and the light receptor which make sure that the print head and the paper are in the right spot. then the group decided that to better show how the printer worked we should separate the print head assembly from the paper intake assembly. so next i took out a total of 5 more screws that were connecting the two half's together, then unplugged all the wires connecting them, separate them and put them on the table and then reconnect the wires. to make sure that the printer was still functional i plugged the printer and turned it on. http://www.youtube.com/watch?v=ZVroYUZWVqc. the printer head was still working and so were the cartridge covers but the printer wasn't taking in any paper. upon rechecking all the wiring i found out that one of the wires was unplugged and after i plugged it back in everything was working perfectly. http://www.youtube.com/watch?v=bFEppLk7qdg. the next step was to mount the whole thing on a wooden board. the paper intake half was easy to mount because it had a flat bottom so i just drilled it in place with one screw. the printer head was a little bit more complicated and had to be raised a little bit for all of its parts to be visible. to mount i drilled two small wooden blocks into the wooden base and then drilled the printer parts on top of it. in the end used double sided tape and mounted the ink cartridge covers on the board.
