Locating tabs can be formed as an integral part of a unit sensitive to accurate positioning and then removed after installation of the unit. In the figure, an emitter block 1 for sensing indicia on a print band has tabs 2 integrally molded thereto. The tabs have a length providing the required installation spacing between emitter transducers 3 and band pulley 4 when contacting the pulley. After installation of the emitter, tabs 2 are broken off at junctures 5 of the reduced or weakened cross section to enable the installation of a print band and operation of the printer.
