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 Makes paper easier to handle Organizes customer projects Good Stacks 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
