Carrier Assembly Circuits
Figure 2-11. Carrier Assembly Circuits.
The Carrier Assembly contains:
1) Carrier PCB
2) Optical Sensors
3) Paper Sensor
4) Inkjet Cartridges
The Carrier PCB 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 MPCB.
The optical sensors receive their inputs from the optical encoder strip
and sends this data to the MPCB. The MPCB uses this information
to determine the horizontal position of the carrier assembly so that
accurate printing can be established.
