Wick for an inkjet printhead

A printhead adapted to receive a removable ink cartridge, the printhead comprising:

• a receptacle dimensioned to receive a removable ink cartridge;
• a nozzle through which ink exits the printhead;
• a filter located in a fluid path extending from the receptacle to the nozzle;
• and
• a wick having
• a first portion positioned to be releasably coupled to an outlet of the removable
• ink cartridge when the removable ink cartridge is installed within the receptacle, the first portion having a total amount of surface area exposed to an interior of the receptacle when the removable ink cartridge is removed from the receptacle;
• and
• a second portion coupled to the filter and located along the fluid path downstream of the first portion, the second portion having a total amount of surface area in contact with the filter, wherein the total amount of surface area of the wick exposed to the interior of the receptacle when the removable ink cartridge is removed is less than the total amount of surface area of the wick in contact with the filter.

A printhead adapted to receive a removable ink cartridge, the printhead comprising:

• a housing;
• and
• a wick positioned with respect to the housing to be releasably coupled to an ink cartridge when the removable ink cartridge is installed in the printhead, the wick comprising
• at least one surface defining a first interface through which ink enters the wick from the removable ink cartridge;
• at least one surface defining a second interface through which ink exits the wick;
• and
• a cross-sectional area defined by a plane substantially perpendicular to an ink flow path extending from the first interface to the second interface,
• wherein the cross-sectional area of the wick changes between the first interface and the second interface of the wick.
