Fuser for electrophotographic printing having resistive trace with gap

摘要

A fuser includes a fuser roll and a pressure roll that forms a nip between the rolls through which a sheet is conveyed to permanently fuse an image onto the sheet. The fuser roll includes a heater element having a single resistive trace, a common trace tapped to a first side of the resistive trace continuous across the resistive trace, and first and second conductive traces tapped to ends of the resistive trace at a second side of the resistive trace opposite the first side. The first and second conductive traces are physically separated and conductively segmented by a conductive gap between the conductive traces. The resistive trace includes a separation gap extending through the resistive trace continuously from the second side of the resistive trace at the conductive gap towards the first side of the resistive trace to prevent current flow between the segmented conductive traces.
