-For the dissection of the Lexmark Z82 all-in-one printer, this page will go through a step by step disassembly process. If a larger view of the picture is wanted, click on the picture and it will take you to another page where the picture is enlarged. In some cases labeling was not used because it took too much away from picture, but what happened was explained in the extra documentation. For tools, unless specified, a class two phillips head screw driver was used (counter clockwise to take out), and a class two flat head screw driver was used for prying and pushing clips out of the way. There were little to no challenges faced due to parts coming off easier than expected, and only needing a portion of the tools stated in our initial analysis. This part was not meant to be taken apart other than opening up the maintenance panel to change ink from time to time, and the paper reservoir being opened and closed to refill paper. We believe this because the purpose of this device is to print information from the computer and to take information in paper form and either duplicate it or put in onto the computer. All these tasks can be accomplished without going deep into the printers main components like its wiring and motherboards. These devices were only meant to be touched or worked on if any in depth maintenance or repair was to occur other than routine changing of the ink. Another reason we say this is because there is no need for screws or clips to be removed or pushed out of the way for this product to function. If any problems occurred, a specialist should take this apart and not anyone else. Lastly, below is a scale to rate how difficult it was to remove each part along with the approximate effort needed to do the task. The scale ranges from 1 to 5 with 1 being a very simple step which requires little time (a few minutes) and no hard work to accomplish, and 5 being a step which was very difficult to complete and required the most time (more than 10 minutes) to finish without completely destroying the part or parts that are trying to be separated or opened.

+	Overall, the work and management proposal predictions were excessive.  The work proposal particularly was overly pessimistic.  The only tools used were a class two Phillips-head screwdriver to remove screws and a flat-head screwdriver to pry apart some pieces. No wire cutter or other similar tool was needed to cut wires as all wires were easily removed.  Hopefully, only the Phillips-head screwdriver will be needed for assembly, as the parts that needed prying should just slide back into place.

	The 3 subsystems are placed in different locations throughout the printer in order to make the printer more compact and visually appealing to the customer, therefore they need a way in which to communicate with each other. Printers go hand in hand with computers because they take the computers information and change it into another form such as printing an electronic document into paper or physical form. The printer we are analyzing also has a scanner with it which does the reverse and takes paper or physical information and turns it into electronic information on the computer. For each subsystem to communicate with each other they would need to be connected by wires. These wires may have different shapes and lengths depending on where they are being used. They also need a way to be physically connect into the subsystems main component, such as a wire from the computer itself needing to be connected to the printers main motherboard in order to communicate with the computer. These connections would be clips or plugs at either end of the wire and would physically be inserted into a connection hole on the components needing to be connected. Each of the subsystems are connected to the other 2 in one way or another, but all need the wires with the inserts at both ends in order to be connected. These wires allow for the subsystems to communicate via signals through the wires to accomplish the task requested such as printing. Creating signals requires some form of energy, in this case electrical energy, for the printer to carry out its tasks. This energy is mainly supplied from the power cord which gives power to the entire printer. Each subsystem is also physically connected to the base or main body of the overall printer to make things more organized and easy to find and understand, as well as keep things somewhat compact. These connections were made mostly by screws and small bolts in order to keep all the components stable and restrained to perform at their best without shaking while parts are moving and causing some error.
