Abstract
A resealed inkjet printer cartridge and method of manufacture in which an ink cartridge is reconditioned, recharged and resealed by a process which substantially eliminates “air lock” or interruption of ink flow to the printer head due to entrained air; which provides for welding together recharged cartridge subassemblies without the use of consumable adhesive or glue; and having a keyless cap adapted for use in various keyed cartridge receptacle inkjet printers.
Claims3
A resealed ink cartridge comprising:
- a cleaned and refilled previously depleted ink cartridge body having a print head in fluid communication whereby a liquid may flow or move between said print head and an ink reservoir;
- and,
- a continuous fluid connection between said print head and said ink reservoir established by centrifugation of said cartridge body containing a liquid to purge air from said print head whereby said liquid forms a continuous liquid path or connection between said print head and said ink reservoir,
- the centrifugation having an axis of rotation;
- the ink cartridge having been retained in an orientation with the print head facing substantially radially away from said axis of rotation during centrifugation.
