ABSTRACT:
A non-impact printing system in which a multi-wire head collects debris has an arrangement for cleaning the head with a brush by sweeping the head over the brush in a first direction and immediately sweeping the head back over the brush in the reverse direction, while simultaneously pulling the head away from the brush.
