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. This enables 600 dpi resolution with single-pass printing.

To enable a horizontal resolution of 2400 dpi, 3-dot printing is made possible in 600 dpi intervals.

There are a total of eight patterns to enable or disable printing between the 600 dpi dots.

Figure 3-4 Printing Driving Method

Since it is impossible to heat the nozzles successively in the horizontal direction at 2400 dpi intervals, the heating is broken into four passes. Thus, 2400 dpi printing requires four or more passes to be driven. However, the places that will be printed during a pass are determined by a random mask pattern. Therefore, it is not fixed.
