Abstract: A system for creating a condition of substantial thermal consistency between multiple printer cartridges includes a frame defining a cavity for supporting the multiple cartridges spaced apart from one another and a plurality of components mounted to the frame in flow communication with one another and with the cavity via the frame. The plurality of components coact with one another and with the frame to generate, regulate and distribute an intake flow of cooling air from the frame into multiple inflows of cooling air along different spaced apart paths at different velocities through the cavity and between the spaced apart multiple cartridges for causing transformation of the multiple inflows of cooling air into multiple outflows of heated air by contact with the multiple cartridges and to exhaust the multiple outflows of heated air from the cavity and frame.

Abstract: A printer is provided including a reference edge, a fuser assembly, a cooling apparatus and a controller. The reference edge is adapted to be contacted by a substrate as the substrate moves along a substrate path through the printer. The fuser assembly includes a heat transfer member including a belt and a backup member. The cooling apparatus is adapted to move cooling air capable of cooling the fuser assembly. The controller is configured to activate the cooling apparatus after determining that a first end portion of the backup member opposite a second end portion of the backup member near the reference edge is at a temperature above a predefined first threshold temperature.
