摘要:
A drive assembly for a printer includes an endless loop drive path and guide structure that allows a printhead to operate in either reciprocal or endless loop modes in which the printed traverse both a liner and an arcuate portion of the drive path. This provides a printer architecture in which a printhead may be endlessly driven at a constant speed in one direction to provide multiple print swaths separated spatially. This eliminates the need for deceleration/acceleration changes required in reciprocal printer architectures and is capable of increased throughput by defining arcuate turnaround zones that can be traversed by the printhead faster than the time it takes to slow, stop and reverse a conventional reciprocal printhead assembly. This robust printer architecture also allows flexibility in use of multiple printheads with simultaneous printing, simultaneous both side printing, and duplex capabilities.

A fluid reservoir sensing system includes a pair of optical prisms that reflect light when a fluid level is below one of the pair of prisms. The pair of optical prisms includes a low prism usable to sense a low liquid level in the fluid reservoir, and a high prism usable to sense a high liquid level in the fluid reservoir. The fluid reservoir sensing system optionally includes an emitter and a photosensor. The emitter projects light through at least one of the low prism to the low incident surface and the high prism to the high incident surface. The photosensor senses light reflected from the low prism while the liquid is below the low prism. The photosensor also senses light from the high prism while the liquid level is below the high prism.
摘要:
An ink jet printer of the type having at least one customer replaceable ink cartridge with an ink monitoring system detects whether or not the ink in the cartridge contains qualified ink or not and adjusts the normal printing mode to a non-normal printing when non-qualified ink is detected, thereby providing the customer the option to print with non-qualified ink with minimized effect on the printer or print quality.

A fluid ejection container system provides a first container that contains the fluid, the first container being evacuated to negative gauge pressure when being filled with the fluid, a second container having a capillary medium that contains the fluid, a passage between the first and second containers communicating the fluid at a level wherein the passage is wetted with the fluid, a ventilation port to communicate air between an interior region in the fluid ejection system and ambient, at least one spill over region to communicate the fluid with the second container, and a plurality of channels to communicate at least the air between the interior region and the second container; wherein the at least one spill over region has sufficient volume to contain a quantity of the fluid that migrates out of the second container. The fluid ejection container system also provides a lid for sealing the first and second containers from the ambient, wherein the channels are disposed on the lid.

A print cartridge includes a manifold that is molded from a polymer including at least one thermally conductive filler material, and a fluid ejector die module attached to the manifold. A method of manufacturing a print cartridge includes molding a manifold at least partially from a polymer including thermally conductive fillers, forming a fluid ejector die module, and attaching the manifold to the fluid ejector die.

A controller for a fluid ejecting system having a refillable container includes an ejection count initializing circuit, routine or application, a count incrementing circuit, routine or application, at least one fluid level indicator, and a fluid quantity circuit, routine or application for determining an expended quantity of fluid, a fluid reserve capacity circuit, routine or application for determining a fluid reserve capacity in the container, an ejection job determining circuit, routine or application for determining a fluid job requirement, a reserve comparing circuit, routine or application to compare the fluid reserve capacity and the fluid job requirement, and a refill condition determining circuit, routine or application to determine that the container is to be refilled. Counts for a ejection amount and a reserve capacity are incremented in response to a specific amount of fluid being ejected from the container. The expended quantity of fluid is based on the ejection amount count subsequent to the fluid level being indicated. The fluid reserve capacity is based on the reserve capacity count and the expended quantity of fluid. The fluid job requirement is based on the expended quantity of fluid and a job number of ejected amounts of fluid. The container is determined to be refilled upon at least a condition wherein the fluid job requirement exceeds the fluid reserve capacity, and a condition wherein the fluid level is below a refill threshold.
摘要:
A refillable fluid reservoir for a fluid ejection head, including a fluid reservoir having top, bottom and side walls defining an interior volume for having fluid; a venting port provided on one of the reservoir walls; and a fluid inlet port provided on one of the reservoir walls, the venting port and the fluid inlet port being located at substantially the same vertical level to increase volumetric efficiency and reduce staining.
摘要:
A refill junction for a fluid container including an exterior surface; a retaining clip having an outer face and an inner face, at least one of the exterior surface and the inner face including at least one capillary.
摘要:
An ink tank and ink tank support structure which contains structural elements which are designed to permit proper installation of the ink tank in the ink tank support structure while minimizing the chances of improper installation of the ink tank in the ink tank structure. A primary ink tank seal is provided in the ink tank, and a relatively low compressive force seal is provided between the ink tank support structure and the ink tank to reduce leakage of fluid from the tank and limit evaporation of fluid from the tank despite repeated insertions and removals of the ink tank from the ink tank support structure. A variable capacity ink tank and an ink tank with staggered height walls are disclosed, as well as a code reader for determining characteristics of ink tanks.
