Development and testing tool for paper handling and/or printer devices

Abstract

A useful development and testing tool for Hewlett Packard paper handling and/or printer devices is presented.The system provides a microprocessor based general architecture integrated by two PCB cards and a software application, used to improve new product design and testing. Paper handling devices operation is based on DC motors, stepper motors and sensors components, so a graphical user interface was developed in order to configure, drive, and test them. The implemented tool allows a time reduction greater than 50% for the development and test of prototypes.
