Note2) Two groups which are divided according to each elements will be divided either even dot or
odd dot when particular lines(level direction line) are formed and eventually, these lines will be
completed at selected resolution. Following is a conceptual figure when full overlap micro-
weave orms a particular line.
Note 3) The way firmware decides which nozzle becomes even dot or odd dot is determined
as it is described below.


If the line which is about to be printed is even line:

First dot prints odd dot lines and 2nd dot prints even dot lines.


If the line which is about to be printed is odd line:

1st dot prints even dot lines and 2nd dot prints odd dot lines. Eventually, horizontal resolution
will be the same resolution as selected one.
[2.Part Line Overlap Micro-Weave]
This printing method is to perform Micro-Weave printing, overlapping a part of nozzles which are
used for printing. As a result, a part of raster which is overlapped consists of different browse with
different nozzles. The figure below shows 1-line Overlap at 5-dot sending as an example with
explanation on the next page.
