An automated workstation attaches residuals to print coils previously assembled into a printhead. The task performed is illustrated in Fig. 1. Here it is seen that print coil 1 has two integral plastic pins 2. The residual 3, is a rectangular piece of non-conductive polyester film with two holes that fit over pins 2. One of these holes is round and the other, hole 4, is elongated, to accommodate tolerances. After placement of the residual, both pins 2 are subjected to heat and pressure, forming a mushroom shaped head 5, as shown, thus staking the residual to the coil. Fig. 2 shows the relationship of coil 1 to printhead subassembly 6. Depending on the type of printhead, it carries either nine or eighteen print coils 1. The workstation attaches a residual 3 to each of these print coils. Fig.
