2.1.1.1.2 Printing Method
This section explains printing method of actual printing such as printing text at various resolution
select/printing mode and graphics printing. In order to prevent white or color banding which are peculiar
problem of ink-jet, new Micro-Weave functions are added to the previous Micro-Weave function. The
number of nozzles and printing mode according to the selected resolution are used separately by a user.
The table below shows relation between selected resolution and printing mode.
1) Full Overlap Micro-Weave
2) Part Line Overlap Micro-Weave
3) Micro-Weave: (same as previous control)

Forward Overlap-Nozzle and backward Overlap -Nozzle are described in the [1.Full Overlap
Mirco-Weave] and [2.Part line Overlap Micro-Weave] below.
Following explains operation outlines of new Micro-Weave functions listed above.
[1. Full Overlap Micro-Weave]
In order to print one line at horizontal direction, this printing method is designed to complete a printing
pattern by two-pass carriage operation with two different types of dot. When this two different types of dot
pass one same line twice, it does not print the same dot twice.
The nozzles whose configuration completely match to the black and CMY nozzle are used.
(Usually Micro-Weave type)
Therefore, all nozzles in case of CMY nozzle and #1•`#63 nozzles in the B2 line in case of
black head are its objects. (B1 line is not used at Micro-Weave. Refer to figure1-1 for detail of
nozzle configuration.)
Out of these 4 color nozzle objects, the number of all nozzles which are going to be used are
divided equally into 2 groups.
Paper feeding will be done as many as each number of nozzles which are divided into two
groups and the same number of dots.(for example, if there are two 10-nozzle groups during
360-dpi printing at longitudinal direction, paper feeding of 10/360-inch becomes available.)
At this time, two groups perform Micro-Weave individually and particular lines are passed by
two different nozzles.
Note1)
These nozzles which are divided into two groups must be set and divided in order to
be a pair of odd and even number.
