Outline of Operation, cont'd.
When the printing operation starts, the head moves to the printing
position, and the pick up and feeder systems feed the paper. The
printing position of the paper is counted after the TOF inlet sensor
detects a TOF mark or hole or the gap between labels on the paper,
and when the printing position on the paper has reached the BJ head
(black), an equivalent of one line of the printing data is sent to the
BJ head from the image processing unit to execute printing of an
equivalent of one line.
The above-mentioned operation is repeated in synchronization
with the feed of the paper to form images. Likewise, for cyan,
magenta, and yellow, when the printing position of the paper
reaches the respective BJ heads, the printing operation is repeated
to form colour images on the paper.
Basic Operation Sequence of Image Formation System
The basic operation sequence of the image formation system is
