Abstract
A method and apparatus for removing or relocating relatively small air pockets from the reservoirs of ink jet printheads through the use of a decompression technique. In one embodiment, an ink jet cartridge, after being filled with ink, is subjected to a relatively high vacuum by being placed in an evacutable container which is connected to a high vacuum source. The container may hold several cartridges for concurrent processing. In another embodiment, an accessory kit may be used to provide the same decompression process while the cartridge is installed in the printer and located at its maintenance station. The accessory kit could be incorporated into the printer.
