A step motor 1 is mounted within a motor mount 2, which is supported on a carriage in a fixed position. The motor 1 has a print wheel 3 mounted on its shaft 4 so as to position a character on one of the elements of the print wheel 3 for engaging a platen when a print hammer 5, which is mounted on the upper end of the motor mount 2, is energized. An adjustment bracket 6 is attached to the motor 1 by a screw 7. The motor mount 2 has an arcuate hole 8 to enable a locking screw 9 to extend therethrough into a hole in the adjustment bracket 6. When the locking screw 9 is tightened, the adjustment bracket 6 is locked in place on the motor mount 2 to lock the motor 1 against rotation relative to the motor mount 2.
