Ink jet recorder

Abstract

Abstract PURPOSE:To obtain a stable picture where joints between lines are inconspicuous by using a part or all of parts between dots for joints of a preceding main scanning or the next main scanning to scatter the effect of variation in paper feed or variation of dot positions to all regions. CONSTITUTION:Picture data is stored in a main memory 1 and transmitted toward a line buffer according to the order of print by a command of a controller 2. Dot data of an overlapped part to be printed by the 2nd main scanning is transmitted to a line buffer 6 by a data selector 3. When the arrangement of print dot of the overlapped part is regular, the data selector 3 is designated by a counter 4, and when the arrangement is at random, it is designated by a random number generator 4. Print data is transmitted to an electric charge code generating circuit 7 at each one scanning from two line buffers 5, 6, the electric charge code is fed to a D/A converter 9 at the circuit 7 based on the content of a deflection counter 8 and converted into an analog electric charge voltage.
