11. Bit Rotation Logic

11.1 Functional Description

Bit Rotation Logic is responsible for preparing line-based image data to be used for a color or mono inkjet head. It

is designed to be completely universal, so that any inkjet head may be supported regardless of nozzle

configuration, provided there is only one nozzle per line of the printed image. An example of a typical 3-color

inkjet head is shown.

Figure 11-1. Nozzle Diagram of a Typical Programmable Inkjet Head

The inkjet head shown is only an example. There are many other configurations that may be supported. The Bi-

Level Resolution Conversion block works in conjunction with firmware to ensure that all parameters that

correspond to nozzle shifts are removed before the image data is deposited in the swath buffer for removal by the

Bit Rotation Block. In addition, the Bit Rotation block does not need to distinguish the difference between mono or

inkjet color modes. A few examples of nozzle configurations that can be supported are shown in the figures.

These are only to show examples of the universal design.
