The main function of the Carriage is to hold the printhead in position and to move the printhead in a
controlled manner in order to print.
The Carriage holds all the necessary interface electronics for the main board to interact with the printhead via
the trailing cables. A set of spring-loaded connectors are the main interface Carriage-printhead.
NOTE: It is very important that the contacts are clean, free of dust/ink to ensure a correct connection
between printhead and Carriage, as high-speed data are transmitted through this connection, and dust could
cause sporadic system errors. This is particularly important when replacing the printhead, as the removal of
the old printhead (extraction with a rotary movement) can cause the nozzle plate to touch those contacts and
create contamination that could cause problems with the new printhead. However, manual cleaning of the
contacts is not recommended.
The Carriage also has additional functionality:
1. Transmits the pressure from the Prime Pump via o-axis coupling to each of the four cartridges
●
O-axis coupling connects with the Carriage via the side connection bay:
●
An internal passage of the Carriage transmits the air pressure towards the printhead.
