THEORY OF OPERATION

Figure 2-11. Carriage Assembly Circuits.

The Carriage Assembly contains:

1)Carriage PWA

2)Optical Sensors

3)Paper Sensor

4)Inkjet Cartridges

The Carriage PWA contains the logic and drive circuitry for the firing of the inkjet cartridges. It also establishes an interface path for the optical sensor and paper sensor to communicate with the MPWA.

The optical sensors receive their inputs from the optical encoder strip and sends this data to the MPWA. The MPWA uses this information to determine the horizontal position of the carriage assembly so that accurate printing can be established.
