Agenda
Design a system that effectively calculates the velocity of paper as it moves throughout the iGen4
Must detect the velocity of an 8.5”x11” sheet moving somewhere between 250 to 750mm/s
Tolerance level of ±0.25%

LED Infrared Sensor
Best Idea
Infrared’s are cheap, easy to produce in large quantities, and have little maintenance
The typical life span of an LED is around 50,000 hours
Easy to replace
Cost Efficiency
Sustainability◦ Social- Has no adverse impact◦ Environmental- Occasional disposal of LEDs;
minimal impact◦ Economical- Very inexpensive
