In a business machine printer using known metal print band technology, two nylon bristle brushes wipe the surfaces of the print band removing debris, composed of inking ribbon fiber, dried ink, and paper dust, which collects around the print position anvils and tends to migrate to and clog the emitter slots. This cleaning action minimizes problems with light sensing of the emitter slots. The figure shows schematically the arrangement in the present embodiment, in which two nylon bristle brush and holder assemblies 1 are mounted in staggered positions on opposite sides of print band 2. It is seen that as the print band travels in the direction shown (3), the brushes remove debris shown accumulated around print position anvils 4 and emitter slots 5 cleaning them as shown at 6 and 7, respectively.
