2.2.2.4 Pseudo Four-color Mode
This print mode can be selected in the detail setting mode when the plain paper is
selected, and means the draft mode.
In this mode, the printer operates as a pseudo four-color printer, with Lines A and B
used for one color of BK, Lines C and D for one color of C, Lines E and F for one color
of M, and Line G for one color of Y.
Therefore, since two lines of head nozzles are used as one color for each of BK, C and
M, 192 nozzles are used for each color and the printing resolution is 360 x 360dpi. For
Y, the resolution is 360 x 180dpi and 96 nozzles are used.
The JFK of the driver creates the four-color 360 x 360dpi mode and sends it to the
printer. For Y, however, the dot structures of the top and bottom lines are ORed to print
on one line.
