Lexmark Z82 Disassembly
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.
| Scale number | Things that were done | Effort needed |
|---|---|---|
| 1 | Nothing was done but will lead to another step | Very little to no effort |
| 2 | Screw(s) taken out | Little effort |
| 3 | Clip(s) taken out | Slightly difficult, moderate effort |
| 4 | Combination with screw(s) and clip(s) | Moderately difficult, requires extra time and effort |
| 5 | One of the above steps along with extra force needed | Difficult, Requires a substantial amount of force and effort. May require more than one person |
