Fluid delivery for printhead assembly

An electrostatic discharge protection system for use in connection with a pulley or sprocket of the type having a central hub portion and opposite side portions. The hub portion is electrically non-conductive and is rotatably carried on a conductive shaft. The side portions are provided with conductive portions or members. A zener diode is connected between each conductive portion and the conductive shaft to enable electrostatic charges on each side of the pulley or sprocket to be safely drained off. Electrostatic charges present on strip material drawn over a pulley, sprocket or guide are also drained with the protection system. The system is also useful in connection with fixed guides which do not rotate.
