Abstract
Marking apparatus for moving a marking head to coordinate positions utilizing two fixed stepper motors performing in conjunction with a cable and pulley drive system. The dynamics of pneumatically driven marrker pins within marker heads are accommodated for by a topology which includes a marker support base which, in turn, is supported in force transfer relationship with an air bearing which rides over a fiat platen surface. Improved marker head structure is developed utilizing a polyetherimide material and a design providing the introduction of return air into a two-component piston chamber at a location above a seating surface.
