Abstract
Customer Needs Weighting
Xerox machines are a staple in the professional world for their ability to accurately and quickly print paper. A problem with the printed paper though is that it is not always stacked in a uniform way. Users also need two different types of stacks, one offset and one not offset. Our design will make the Xerox machine stacking component be accurate to within 5 mm of the desired stacking type.

ConclusionOur final design is centered around replaceable parts for the different stacks required. An angled component allows for the stacks to become offset, and the non-offset component allows for precise stacking, as well as ease of removing the paper. When the components are not in use, they can be hung off the back of the machine. With this method, different types of molds can be created with ease for different types of stacks a company may require beyond those engineered for the project.
