Abstract: An ink jet cartridge which includes an ink jet housing including a first valve and a primer portion coupled to the ink jet housing and covering the first valve is disclosed The primer portion includes a priming bulb and a second valve in the priming bulb, air flowing into the ink jet housing via the first bulb when the priming valve is actuated, air flowing into the priming portion via the second valve when the priming bulb is released.

Abstract: Information handling system peripherals that use a heating element are protected from catastrophic failure due to overheating by a thermal failsafe associated with the heating element that fails the heating element if excessive temperatures are reached. For instance, the failsafe releases the vacuum from a heating element bulb so that the application of power to the filament of the heating element bulb oxidizes the filament resulting in failure of the filament and ceasing of generation of heat. The failsafe includes a melting agent, such as wax or solder, which seals an opening in the bulb unless a thermal runaway temperature is reached in excess of a desired operating temperature. Alternatively, the failsafe includes an expanding agent, such as a ceramic or a liquid-filled bubble, which releases the vacuum by fracturing an opening in the bulb at the thermal runaway temperature. The thermal runaway temperature is selected to induce failure before catastrophic overheating of the peripheral.

Abstract: Products having sensitive regions, such as information handling system components have electrical connections or openings, are packaged with the sensitive region sealed. A sealing portion on the inner surface of a wrapper has an adhesive surface that adheres the wrapper to the sensitive region so that the wrapper encloses the product with the sensitive portion sealed. For instance, an ink jet cartridge printhead adheres to the sealing portion so that enclosing the cartridge in the wrapper packages the cartridge with the printhead sealed. Removal of the wrapper from the cartridge exposes the printhead for use in an inkjet printer.
