Abstract: An ink jet printer is configured in a hybrid architecture wherein a full width printbar is combined with a partial width color scanning assembly to provide the capability of selectively printing in black only or, alternately, of producing color prints by operating the color scan assembly exclusively. The cost of the hybrid system, when compared to a full width color system using four full width printbars, is greatly reduced. Throughput time is reduced by providing the control circuitry for distinguishing between black only and color operation and selectively controlling the printer mode of operation. The hybrid architecture is particularly useful in a LAN system since it provides a mechanism for balancing the relative color versus black page decomposition speed limitations. Also, the hybrid architecture enables a relatively simple implementation of a checkerboarding technique to suppress banding in output prints.

Abstract: Balanced injection molding in a multi-cavity mold of a plurality of ties having a uniform maximum thickness between opposite broad sides of the tongue of the tie is accomplished by providing mold pieces in which the relative dimensions of projections for forming ratchet teeth on the tongue of the ties in different mold cavities are non-uniform such that when plastic material is injected into the mold cavities, the injected plastic material flows through the different mold cavities at respective flow rates that cause the mold cavities to be completely filled approximately simultaneously with the injected plastic material. In making the mold pieces, the dimensions of the projections initially are larger than required for forming ratchet teeth of a preferred dimension. After measuring the extent to which the different cavities are filled, the relative dimensions of the projections are adjusted such that the projections for at least one of the mold cavities are of a dimension required for forming ratchet teeth of the preferred dimension and/or such that the projections for at least one the mold cavities are of a dimension larger than required for forming ratchet teeth of the preferred dimension and the projections for at least another of the mold cavities are of a dimension smaller than required for forming ratchet teeth of the preferred dimension.
