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.

Keywords: Tool development, paper handling and printer devices, hard-software codesign, testing.

 

RESUMEN

Se presenta una herramienta para la prueba de dispositivos Hewlett Packard de manejo de papel y/o impresión. El sistema tiene una arquitectura de microprocesamiento integrada por dos tarjetas PCB y un programa para mejorar el diseño y la prueba de nuevos productos. La operación de los dispositivos de manejo de papel está basado en motores DC, motores de pasos y sensores, por lo que se desarrolla una interfaz de usuario gráfico para configurarlos, manejarlos y probarlos. Esta herramienta permite una reducción de más del 50% del tiempo de desarrollo y pruebas de prototipos.
