Abstract
A printhead cartridge mounts within a carriage of a printer. The carriage moves along a first direction within the printer. The printhead cartridge includes an inkwell for storing ink, which has a front surface and a bottom surface, a printhead mounted on the bottom surface, and a plurality of contacts for receiving signals from the printer and to provide the signals to the printhead. A centerline of the front surface, running perpendicular to the first direction, evenly defines first and second sides of the front surface. The contacts are disposed on the front surface, and a distribution of the contacts on the first side exceeds a corresponding distribution of the contacts on the second side.
