  • Page 56: Print Drive Method

    Part 3: Technical Reference S600 1.2 Print Drive Method To print, the printer ejects ink from ink nozzles. To this end, 16-bit serial data is transferred once as a latch signal to each nozzle array (total of 8 arrays: black even/odd-number array, cyan, magenta, yellow/even/odd-number array).

  • Page 57: Print Drive Control

    Part 3: Technical Reference S600 1.2.1 Print drive control Print driving is executed as follows: a) The nozzles to be heated are selected in blocks. The nozzles to be heated are selected according to logical blocks of 16 nozzles divided from among the nozzle arrays. In the case of the black nozzles, they are divided into 10 blocks.

  • Page 58: Print Driving Method

    Part 3: Technical Reference S600 1.2.2 Print driving method The printer's drive system enables a maximum of 600 600 dpi for black and 2400 2400 dpi for color. The vertical resolution applies to two nozzle arrays for each color. In the case of black, the two nozzle arrays have 300 dpi. Since their relative position to each other has been shifted by 600 dpi, both nozzle arrays together attain 600 dpi resolution.

  • Page 59: Control During Printing

    Part 3: Technical Reference S600 1.3 Control During Printing The printer can produce high-quality printing with no smearing or irregular density with the cartridge, selected media, printing quality setting, printing data, etc., by altering the carriage operation, paper feed operation, etc. By shifting the printing timing with multiple passes during printing, one raster is printed with multiple nozzles.

  • Page 60: Smear Control And Rest Between

    Part 3: Technical Reference S600 1.3.4 Smear control and rest between pages Both smear control and the rest between pages are for preventing smearing by the edge of the printed paper sliding against the preceding printed page. If pigment ink is used for high-duty printing, smear control can delay the printing operation right before the next sheet of paper is stacked on the printed sheet.
