Problems solved by technology

The other components of the pump add to the complexity of printer manufacturing, and a large number of components will more or less increase the probability of printer failure as a whole due to their individual failures

Embodiment Construction

[0018] The same symbols in the various drawings represent the same components. With reference to the accompanying drawings, figure 1 Shown is an ink delivery system for a printhead 38 on a moving carriage, which includes an ink pump 12 on the moving carriage, wherein the ink pump 12 has a carriage container 14, the carriage container 14 is connected to an ink delivery container 16 by an ink delivery tube 18. The ink delivery tube 18 includes a one-way check valve 20 to control the flow of ink through the ink delivery tube 18 . It is preferred, but not necessary, to have a structure that includes the check valve 20 to regulate the flow of ink through the ink delivery tube 18 .

[0019] The carriage container 14 includes at least one flexible wall 22 which deforms due to the inertial resistance to the acceleration of the moving carriage and thus the ink pump 12 . The flexible wall 22 preferably has an integrated block such as a weight 24 to increase the inertial resistance of...

Abstract

A system and method for supplying ink to a print head on a moving carrier using the acceleration of the print head carrier to assist in pumping the ink. The system includes an ink supply reservoir and an ink pump on the moving carrier where the ink pump has a carrier reservoir including at least one flexible wall that deforms from inertial resistance to acceleration of the moving carrier, a print head, and a pressure regulator in fluid communication with the carrier reservoir and the print head. The flexible wall preferably includes a mass integrated therewith that increases inertial resistance to the acceleration of the moving carrier and deformation of the flexible wall. The system also has an ink supply tube in fluid communication with the ink supply reservoir and the carrier reservoir such that acceleration of the moving carrier and ink pump deforms the flexible wall and thereby pumps ink from the ink supply reservoir to the carrier reservoir and from the carrier reservoir to the print head.

Description

technical field [0001] Generally, the present invention relates to printers. More specifically, the present invention relates to a pump that utilizes the inertia of moving the printhead carriage to pump ink from an ink delivery reservoir to the printhead. Background technique [0002] A common ink supply in a printer, such as an inkjet printer, delivers a continuous stream of ink from a stationary ink reservoir either to a carriage reservoir on the printhead carriage or directly to the media on which it is printed Such as a print head that moves intermittently across a sheet of paper. To direct the flow of ink from the ink delivery container and ultimately to the printhead, the printer may include a device, usually a pump, which is used to create a certain pressure on the ink in the system. Pumps and other devices deliver positive pressure to the ink delivery container to squeeze ink from the ink delivery container, or negative pressure at the printhead carriage to suck in...
