Assigned nozzle values

Usable nozzles

Figure 6-2. Values assigned to the print nozzles

It is not a coincidence that the values that are assigned to the pins are powers of two. These assigned values are the decimal equivalents of the binary values of the nozzles. This means that each combination of nozzle values produces a unique sum; there is never any doubt about which nozzles are supposed to print. Figure 6-3 shows some examples.
