according to the selected media type, print quality, print data and so on.
Printing is performed for each color using a maximum of 16 paths in each print mode according to the selected print quality.
This reduces density irregularities caused by the variation in the amounts of ink discharged from individual nozzles. In addition, it shifts the printing timing so that
the current ink layer is nearly fixed before the next ink layer is applied, thus minimizing bleeding.
Even in the same mode, the printer operates in a different way depending on the media setting made using the printer driver.
a) Draft mode
In the draft mode, image data is thinned out and a single band (equivalent to the width of a nozzle array) is printed using two paths.
To use this mode, select "Draft" under "Print Quality" in the printer driver.
b) Standard mode
In the standard mode, a single band (equivalent to the width of a nozzle array) is printed using 4-8 (4, 6, or 8) paths.
To use this mode, select "Standard" under "Print Quality" in the printer driver.
c) High quality mode
In the high quality mode, a single band is printed using 8 or 12 paths.
To use this mode, select "High" under "Print Quality" in the printer driver.
d) Highest quality mode
In the high quality mode, a single band is printed using 12 or 16 paths.
To use this mode, select "Highest" under "Print Quality" in the printer driver.
