Abstract
Some embodiments of the present invention provide an inkjet printhead within which a removable ink cartridge can be installed. Upon installation, the ink cartridge can be coupled to one or more wicks in the printhead for establishing fluid communication between one or more chambers in the ink cartridge and nozzles through which ink exits the printhead during operation. The wick can extend from a cartridge receptacle to a filter in order to transport ink from the removable cartridge to the filter. In some embodiments, the wick is retained in place within the printhead by a cap, which can be coupled to one or more filter towers. The wick can have upstream and downstream interfaces that can be the same or different in shape and/or size.
