Abstract
A reciprocating belt drive arrangement for the printhead carriage of a printer comprises an endless belt looped around a toothed drive pulley, which engages a toothed part of the belt, and an idler pulley with circumferential grooves which are arranged to receive ribs on the remaining part of the belt to prevent transverse movements of the belt leading to wear. The ribs and grooves may be interchangeable. In an alternative embodiment the toothed and ribbed parts extend side-by-side along the belt.
