Abstract
An ink supply system for an ink jet printer has an ink circuit including a plurality of circuit components and fluid paths for conveying ink between components. A manifold defining the fluid paths and a plurality of ports in fluid communication with the paths. A filter module is provided adjacent to the manifold and comprises a housing that houses at least a first filter, the housing having an inlet and an outlet. The filter module is connected to the manifold such that at least one of the inlet or the outlet is in fluid communication with one of the plurality of ports on the manifold. The filter module may comprise an ink filter and a solvent filter. A second ink filter may be provided upstream of a pump. The modular nature of the filter makes for easy assembly, service and repair. It also provides for improved printer reliability.
