Abstract
A power supply for a printhead assembly includes a first strip of an electrically conductive material, the first strip having a pair of spaced terminals projecting from a side edge thereof and a second strip of an electrically conductive material, the second strip having a single terminal projecting from a corresponding side edge thereof. The arrangement is such that, when the two strips are arranged side by side, the single terminal of the second strip is arranged between, and equidistantly from, the two terminals of the first strip. A strip of insulating material arranged between the two strips. This symmetrical arrangement of terminals reduces the liklihood of reversing polarity when the assembly is installed. The assembly also includes a TAB film to which a Memjet chip is affixed and which is electrically connected to resilient contact fingers on the two strips and also to a flexible film joined to a data connector.
