    摘要： An image formation apparatus provided according to the present invention does not generate any printing density streaks in low density areas of an image and is therefore capable of outputting stabilized images without any density unevennesses and density streaks in any tonality. The apparatus is structured so as to correct density signals in accordance with a correction table 1 for indicating the recording characteristics of each of the recording elements of the head and the recording characteristics indicated by this correction table 1, and to drive the recording head in accordance with a correction table 2, which does not allow the fore-going corrections to be made when the density signals are lower than a given density, and the density signals corrected by this correction table 2.

    摘要： 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.

    摘要： A method of exchanging a waste ink pack that stores waste ink discharged by repeated ink clearing operations performed on an ink jet head involves comparing a cumulative number of times the ink clearing operation have been performed using a particular waste ink pack with upper limit data based on the capacity of the waste ink pack. When the cumulative number reaches the upper limit data, an indication is provided that the waste ink pack should be exchanged for a new one, after which exchange a previous instruction to a recovery device to perform an ink clearing operation is performed. Ink clearing operations are then repeated with that waste ink pack until the number of such operations again reaches the upper limit data.
