An ink cartridge for an inkjet printer is configured to keep the ink pressure in the printhead constant. The cartridge has a sealed ink storage volume, an ink outlet for sealed fluid communication between the printhead and the ink storage volume, an air bag in the ink storage volume for expanding as ink is drawn through the ink outlet to keep a constant head of ink above the outlet valve. The air inlet for the air bag is a frangible that is ruptured as the cartridge is installed and the ink outlet opens.

A printhead assembly includes a printhead module including two or more printhead integrated circuits and an electrical connector for connecting electrical signals to the printhead integrated circuits. First and second power supplies are provided at first and second ends of the printhead assembly, the second end being opposite to the first end. The printhead assembly further includes a plurality of electrical conductors for providing power to the printhead integrated circuits from the first and second power supplies. The plurality of electrical conductors extend transverse to a media feed path defined through the printhead assembly. The plurality of electrical connectors are arranged as first and second groups of electrical conductors, the first and second groups having a combined lengths at least equal to a width of the media feed path. The first group of electrical conductors is connected to the first power supply and extends from the first end of the printhead assembly to a region intermediate the ends of the printhead assembly. The second group of electrical conductors is connected to the second power supply and extends from the second end to connect to the first group at the region intermediate the first and second ends of the printhead assembly to supply power in parallel from both ends of the printhead assembly. The first group of electrical conductors has a staggered configuration, the staggered configuration adapted to overlap and mate with a complementary staggered configuration of the second group of electrical conductors.

A cartridge unit for an inkjet printer is provided which has a body portion having ink storage compartments, a pagewidth printhead configured to receive ink from the compartments and distribute the ink to nozzles arranged in use to deliver the ink onto passing print media, and a capping assembly for capping the printhead. The capping assembly has a body which extends the printhead length, a capping element housed within the body and having a rim portion which caps at least a portion of the printhead and a displacement assembly housed within the body for moving the capping element between a first position where the rim portion extends from the body and a second position where the rim portion is contained within the body. The displacement assembly is controlled by an electromagnet which determines the position. The ink storage compartments comprise absorption material which stores the ink under capillary action.

An inkjet printer that has a filter with a chamber divided into an upstream section and a downstream section by a filter membrane. An inlet conduit establishes fluid communication between an ink supply and the upstream section. An outlet conduit establishes fluid communication between the downstream section and a printhead. During use at least part of the inlet conduit is elevated relative to the filter membrane. By elevating the inlet conduit relative to the filter membrane, it acts as a bubble trap to retain bubbles that would otherwise obstruct the filter. This allows the filter size to be reduced for a more compact overall design.

Provided is a printer assembly having a refillable cartridge assembly. The cartridge assembly includes an elongate main body defining a number of rectangular ink reservoirs along a length thereof, with end reservoirs being larger than reservoirs interposed between the end reservoirs, said end reservoirs being configured to store ink more readily consumed during a printing process. The cartridge assembly also includes a lid assembly covering the main body to seal ink inside the ink reservoirs, the lid assembly having an actuator to actuate a cartridge refill unit. Also included is a printhead assembly fast with the main body and operatively fed with ink from the ink reservoirs in the main body, as well as a refill unit engageable with the lid assembly to refill at least one of the reservoirs.

Provided is an ink refill unit for a print engine. The unit includes a body assembly defining an ink ejection port at one end thereof, a compressible tank located inside said body assembly, and a compression arrangement for compressing the bellows tank. The compression arrangement includes actuation means selectively operable by a controller of the print engine, a threaded wall and circular plunger assembly, and an elongate drive gear mounted within the body assembly and engaging with the plunger assembly. The drive gear is actuated by the actuation means. The threaded wall and circular plunger assembly includes an internal lead screw provided in a substantially cylindrical internal wall of the body assembly and a helical geared thread provided about the circumference of a substantially circular plunger threaded to the internal lead screw thread and extending along a length thereof. The lead screw thread is provided with a gap along the length of the body assembly in which the drive gear sits and is able to come into contact with the geared thread of the plunger.
