  • Patent number: 6454388
    Abstract: A technique for handling residual ink that is from time to time present on the orifice plate of an ink-jet print cartridge. In one preferred embodiment, an ink-jet print cartridge is equipped with an ink-receptive member, such as an absorbent pad. The pad is located so that a service station wiper will move the residual ink from the orifice plate and spread it across the pad. The pad absorbs the ink. In essence, the ink is sequestered on the cartridge, in the pad. The exterior surface of the pad dries quickly so that there is little likelihood of developing a tacky area over the pad to which fibers may stick and degrade print quality.
