2.3 Print Control

2.3.1 Print mode

This printer is capable of fast, high-quality printing without blurring or inconsistent
ink density by changing the carriage operation, sheet feeding operation, and other
printing methods according to the selected paper, print quality, and print data.
Printing is performed for each color using multiple passes. This enables reduction of
concentration irregularities caused by the range of discharge amounts for each nozzle,
and the print timing is shifted so that the printed ink is virtually fixed before the next
ink layer is applied in order to minimized bleeding.
The printer supports a maximum of 10-pass printing according to the required print
quality.
a) Draft mode
In the high-speed (draft) print mode, the image data is thinned out and a single
band (equivalent to the width of a nozzle array) is printed in a 2-pass or 4-pass
operation.
This mode is used by selecting the "Draft" option under Print Quality settings in the
printer driver.
Print operation in the high-speed print (Draft) mode varies according to the sheet
settings selected in the printer driver. If Plain Paper or Coated Paper is selected in
the sheet settings, the image data is divided into two parts for each color under
mask pattern control and printed in 2-pass bi-directional format. For Plain Paper,
the paper is fed by the length equal to the nozzle width every two scans. For Coated
Paper, the paper is fed by the length equal to 640 nozzles per scan.
If Heavy Coated Paper is selected in sheet settings, the image data is divided into
two parts for each color under mask pattern control, further divided into two parts
under nozzle block control and printed in 4-pass bi-directional format.
b) Standard mode
In normal print mode, a single band (equivalent to the width of a nozzle array) is
printed in 4-pass or 8-pass operation.
This mode is used by selecting the "Standard" option under Print Quality settings
in the printer driver.
The printing operation varies depending on the sheet settings in the printer driver.
If Plain Paper is selected in the sheet settings, the image data is divided into two
parts for each color under mask pattern control, further divided into two parts
under nozzle block control and printed in 4-pass uni-directional format.
If setting other than Plain Paper is selected, the image data is divided into four
parts for each color under mask pattern control, further divided into two parts
under nozzle block control and printed in 8-pass bi-directional format.
c) High mode
In high quality print mode, a single band is printed using 8-pass operation.
This mode is used by selecting the "High" option under Print Quality settings in the
printer driver.
The image data is divided into four parts for each color under mask pattern control,
then divided each into two parts under nozzle block control, and printed in 8-pass
bi-directional format.
