Xerox Project

1. Xerox Project • Kyle Gerheiser • Jake Stanko • Stephanie Kumi

2. Table of Contents • Problem Statement + Need • Stacks • Customer Needs • Laser • Pressure • Optical • Infrared • Criteria • Matrices • Design Selection + Analysis • Summary

3. Xerox iGen 4 • Commercial printer • 110 ppm • 200,000 - 3,750,000 pages per month • 4,800 x 600 resolution • Modular Design

4. Problem Statement/Need • Bad stacks can cause job integrity issues and lead to stacks falling over • We recognize the need to design a sensor that detects stack quality

5. Stacks Good Stacks • Makes paper easier to handle • Organizes customer projects Bad Stacks

6. Customer Needs • Detect bad stacks within a tolerance of 5mm • Design a sensor for the iGen4

7. Laser • Position detection laser • Detects an interruption in the stack • 3 sensors to measure each axis

8. Pressure Sensor • Detects variations in the weight distribution of the paper • If stacks are aligned properly, each sensor will be the same

9. Optical Sensor • Uses a camera and optical recognition to detect paper placement • Placed above the paper

10. Infrared Motion Detector • Uses infrared light to detect variance from a perfect stack • Similar to Laser

11. Criteria • Cost • Complexity • Ease of Installation • Upkeep

12. Matrices

13. Design Selection + Analysis • Our best idea was the infrared sensor • Best score in all criteria • 3 infrared detectors for each axis

14. Summary • Final choice is Infrared Sensor • Technology already in use and easy to implement in the iGen4 • Best choice
