Print modes Print methods, such as carriage and paper feed operation, are varied according to the media type, print quality, kind of print data and so forth to achieve high-quality high-speed print free from blurring and uneven density. Because each color prints in up to 16 passes according the print quality requirement for a print mode, uneven density problems caused by variations in the rate of discharge among different nozzles are eliminated. Deferred print timings do not allow a new ink to overprint the preceding ink until the preceding ink has virtually fixed, thereby reducing the chances of blurred printing. Different operations take place even in the same print mode according to the paper setting of the print driver. a) Draft mode Imaging data is thinned out to print in one or two passes per band (equivalent of the length of a nozzle). Configure the print driver for print quality Draft to enable draft mode b) Standard mode Imaging data prints in one to six (one, two, four or six) passes per band (equivalent of the length of a nozzle). Configure the print driver for print quality setting Standard to enable standard mode. c) High quality mode Imaging data prints in two, four or eight passes per band. Configure the print driver for print quality High to enable high quality mode. d) Highest quality mode Imaging data prints in eight or 16passes per band. Configure the print driver for print quality Highest to enable highest quality mode.
