Customer Needs

Revised Problem Statement Our initial problem statement included creating a system that detects paper stiffness inside a printer or copier. We intend to stick to this objective, but we want to make sure our final design implements our most important customer needs. These include being consistent and accurate, for our system is being designed to eliminate human error, and it also must be able to process printing jobs quickly, without adding unnecessary time to the digital printing process.

It is our objective to develop innovative concepts for key paper handling areas in a digital printing system. Specifically, we are to create a system that detects paper stiffness within a printer or copier, and adapts to the data received.
