Tungsten carbide wires which are used in wire matrix printheads are prone to wire fracture. The demands for faster throughput with improved print quality may aggravate this condition with the implementation of curved, longer wire paths and smaller diameter wires. Conventional printheads support the wires with spaced inserts or completely molded wire paths. These designs have unsupported sections due to friction considerations, wire alignment and printhead assembly.
