Nozzle Arrangement - Canon BJ-W3000 Service Manual

CHAPTER 2. BASIC OPERATION

4. Nozzle arrangement

160 nozzles are arranged vertically in one line at a spacing of 1/360 in.
Nozzle arrangement on the BJ print head is shown below.
In the monochrome mode, 1 band is printed at a maximum width of 160 nozzles (approxi-
mately 11.3mm) .
However, in color mode, 4 BJ print heads are used, and the printer must compensate for
variations in discharge due to each printhead installation tolerance and nozzle tolerance. For this
reason, though the head is composed of 160 nozzles, one band has a width corresponding to 144
nozzles at the maximum (about 10.2mm), and the particular nozzles used on the printhead of
each color are determined each time that "Auto Adjust" of the "Adjustment" menu is executed.
