The Stylus Color printer has a special printing mode,

microwave mode, for printing raster

graphics. This printing mode can be selected from the custom driver. Using the microwave mode
can improve the quality of output because it

tes the banding that can sometimes

normal mode. In microwave mode, the paper feed

is performed after each print pass,

thus eliminating the pitch variation as the paper feed that causes the banding.

Microwave print mode is available for both 360-and

resolution.

Normal mode

Normally the printer uses all nozzles for printing and each print line is completed in one pass.
But if the image data contains both

e and color in a single print line, the printer

the line in four passes even for monochrome printing ( 1/360 x 4 line

because if

the image data contains color in a single print line, it uses only 16 nozzles in row A of the black
head.

Microwave mode

In microwave mode, the printer

the whole image as a single image rather than as

continual lines. In this mode, the printer uses only 15 nozzles of row A of the nozzles (#1 to
#lS). After printing the first pass, the printhead moves to a new position 15/360 inch forward.
The printer repeats this sequence until it finishes printing the whole image. In microwave
mode the printing starts from the under nozzle (#57 pin).
