A replaceable printing subassembly is disclosed. The replaceable printing subassembly includes a printbar. A fluid delivery system including a pump is fluidically coupled to the printbar. A frame is coupled to the fluid delivery system. The replaceable printing subassembly also includes a lift mechanism having an actuator to selectively move the printbar with respect to the frame.

Replaceable printing subassembly

A printing subassembly is disclosed. The printing subassembly includes a printbar. A frame is coupled to the printbar such that the printbar dos not move with respect to the frame. A fluid supply system is coupled to the printbar.

Printing subassembly

Fluid couplings examples are disclosed in examples herein. An example printer includes a housing; and a fluid reservoir permanently fixed within the housing, the fluid reservoir having a capacity sufficient to store enough ink to print a number of pages that corresponds to an expected useful life of the printer.

Printers

Example fluid couplings, systems and methods are described including a fluid delivery tube for delivering fluid to a fluid supply, a fluid interconnect fitting for connection to the fluid delivery tube, a retainer for engaging the fluid interconnect fitting and a fluid supply for retaining the fluid interconnect fitting with respect to the fluid supply, and a seal feature arranged to mate with the fluid interconnect fitting and a fluid inlet of the fluid supply.

Fluid coupling

In one example, an ink supply assembly that may be installed into a printer as a single unit while holding ink includes a first sub-assembly having a primary container to hold ink and a secondary container enclosing the primary container and configured to fit inside the printer. The assembly also includes a a second sub-assembly having an ink supply to receive ink from the primary container through a conduit and to deliver ink to a printhead.

Liquid supply

Colorant transfer, involving a colorant supply, and impeding colorant from exiting the colorant supply, a motion device, and providing a passage out of the colorant supply.

Colorant transfer systems

In one embodiment, a fluid ejector assembly includes: a bay for holding a detachable fluid container that includes a fluid outlet at a forward part of the container; a fluid ejector; a fluid inlet at a forward part of the bay through which fluid from the outlet of a fluid container installed in the bay may pass to the fluid ejector; and a stationary guide configured to block an improper installation of a fluid container into the bay without also blocking a proper installation of the fluid container into the bay.

An apparatus and a method retain a print unit in a dock with a retainer that is at least partially below a top of a fluid supply of the print unit.

Print unit latch

In one embodiment a cartridge holder includes: a body having a plurality of bays therein for holding a cartridge and each bay having an electrical connector associated therewith for connecting to a chip; an adapter removably attachable to the body at a bay, the adapter having a site for a chip at a location where a chip installed at the chip site is connected to a connector in the bay when the adapter is attached to the body; and each bay configured to hold: without an adapter attached to the body at the bay, a first cartridge having a first shape and a chip thereon, and, with the adapter attached to the body at the bay, a second cartridge having a second shape different from the first shape and the second cartridge not having a chip thereon.

Cartridge holder

A tube routing configuration for a printing system with an off-axis ink supply system. The system includes a printer housing and a transporting system for transporting a print medium along a medium path to a print area. A scanning carriage holds a printing cartridge with a print-head, the carriage holding the cartridge such that the printhead faces the print zone. A carriage scanning apparatus moves the carriage along a scanning axis transverse to the medium path at the print area. An off-axis ink supply station is mounted in a fixed position relative to the printer housing. Hollow flexible tubing interconnects between the carriage and the off-axis ink supply station to provide an ink replenishment path for the printer cartridge. The tubing is routed between the carriage and the off-axis supply station such that a loop is formed in the tubing, and wherein the loop is substantially contained within a vertically projected volume swept out by the carriage, thereby reducing the need for additional product volume required for the tubing.

Fluidic delivery system with tubing and manifolding for an off-axis

Described herein is a printer having a printhead which traverses laterally across a sheetlike print medium and which thereby defines a laterally-extending print zone across the print medium. A paper transport mechanism in the printer has drive rollers and associated pinch wheels to drive the print medium through the printer's print zone. The paper transport mechanism further includes an upper print media guide and a lower print medium guide. The two print medium guides are shaped at their transverse ends to bow the transverse edges of the print medium downwardly to reduce its tendency to buckle upwardly into the printhead. In order to fit the upper print medium guide into the limited available space above the drive rollers, it is made of a lower molded portion for paper contact and an upper backing portion for rigidity. A pinch finger extends toward the printer's print zone beyond the pinch wheels to establish a pinch point against the drive roller in near proximity to the print zone.
