Abstract
The invention relates to an improved ink jet pen for an ink jet printer. The pen includes a pen body having raised end walls, a recessed substantially planar portion between the end walls containing two or more printheads and flexible circuits therefor, the flexible circuits being attached to the pen body in the recessed portion between the raised end walls. A polymeric material is disposed between adjacent flexible circuits in the recessed portion having a height sufficient to protect a wiper from damage from exposed edges of the flexible circuits between adjacent printheads during a printhead cleaning operation. The improved pen lends itself to simplified manufacturing processes yet provides enhanced mechanical protection of the wiper and critical electrical structures and enhanced corrosion resistance from ink.
