Operation Manual

2.2 Print Modes
The printer selects the carriage operation and bubblejet drive method on the basis of
the media and print quality selected by the driver, and the print data that is received
from the host PC. This enables the printer to achieve optimum print quality, free of
smears and fragmentation.
To improve the quality of images, the printer is designed to print the data using
multiple passes of the carriage.
By increasing the number of passes for the data as a whole, the time required for the
ink for each piece of data to dry is split up, making ink smears less likely.
The printer selects the optimum print mode according to the type of BJ cartridge(s)
installed, the ink system being used, and the various settings, such as print media and
print quality, selected using the printer driver.
