  • Patent number: 8211843
    Abstract: An end user implemented preventative maintenance process, made to clean ink-jet cartridges. The methodology consists of an organic solution injected into a lint free wipe, which, when applied to the print head nozzle surface of an ink-jet cartridge, leaches dried ink, paper lint, dirt, and other contaminants. The use of a lint free dry wipe, to blot any remaining ink from the print head nozzles after cleaning, provides streak-less printing, and assures the end user that preventative maintenance has been accomplished. Using this process noticeably extends the useful life of ink-jet print cartridges, while maintaining the integrity of print quality.
