The NEC CP6 and CP7 printers (colour variants of the P6/P7) also used such an arrangement - wheels sliding along profiled shafts and small toothed belts to change the height of the ribbon guide on the printer carriage by means of a stepper motor mounted on the chassis. I had the "fun" of repairing a broken guide bridge on mine (had to fit a reinforcement under the crack and reassure it didn't bind or collide with anything).
