  • Tone recording method using ink recording head
    Patent number: 5430469
    Abstract: A liquid jet recording method of recording on a recording material with liquid droplets discharged trough plural scanning nozzles, in which:n/(s/p).gtoreq.2n/(s/p).times.k=g-1are satisfied,where n (n.gtoreq.2) is a number of the nozzles arranged at pitch P (.mu.m); s (.mu.m) is a distance of relative movement between the nozzles and the recording material between adjacent scans; k (k.gtoreq.1) is a maximum number of ink droplets per pixel and per scan; g (g.gtoreq.3) is a number of tone levels.

  • Ink jet apparatus and method of recovering ink jet head
    Patent number: 5355158
    Abstract: An ink jet apparatus includes an ink jet head having in energy generator which car, generate energy employed for discharging ink as a droplet from a discharge port, and a control unit for controlling the energy generated from the energy generator so as to remove ink droplets, which adhere to a discharge port surface, by spreading the meniscus of the ink projecting from the discharge port on the discharge port surface. The apparatus is therefore capable of removing floating ink mist particles which adhere to the ink jet head.
