Abstract
An internal heating system for an image transfer drum is disclosed that can include a box having a plurality of sides, an open side facing the drum and a heater element. The box can have small gaps between it and the internal drum surface to maximize thermal efficiency of the internal heating system. The heater element can include first and second support structures that are disposed on a central support structure, the first support structure having an end connector at one side away from the second support structure. The heater system can also include at least two circuits, two channels and a relay switch, with the relay switch operating to switch the circuits into a series or parallel electrical configuration.
