within the most upper sector and the second upper sector and then go to the third upper sector. (4)When YLEN is more than 24 dots(18H) and less than or equal to 32 dots(20H), the YLEN should be divided by 8 into four sectors. Then the block image data should be made as the same procedures as above within the most upper sector and the second upper sector and the third upper sector and then go to the last(bottom) sector.
