A vibration isolation system, including a housing and a first isolation member which further includes a receptacle to receive an outer body of a motor, a first plurality of compliant arms, and a second plurality of compliant arms. Each compliant arm of the first isolation member has a first end and a second end. The first end of each of the compliant arms is coupled to the receptacle, and the second end of each of the compliant arms is coupled to the housing.

Vibration isolation system

Printers and duplexers are described herein. An example duplexer for a printer includes a waste ink roller movable between a concealed region and a receiving region.

Printers and duplexers for printers

Printers and duplexers are described herein. An example duplexer for a printer includes a print substrate path to guide a print substrate and a chamber to collect a fluid.

One embodiment of a method for refurbishing a web cartridge includes separating a web extending between first and second spools from the first spool and winding the separated web onto the second spool. The first and second spools are removed from a housing. A replacement first spool having a replacement web is obtained, and an end of the replacement is fed web through a web guide. A portion of the replacement web is then affixed to a replacement second spool.

Methods for refurbishing a web cartridge

A method and apparatus raise and lower a web support and move a cap over and above the web support.

Movable web support and cap

An exemplary printer system may include a print head for dispensing ink during a printing operation. A roller is positioned beneath a platen to collect excess ink from the print head. A scraper is positioned against the roller to remove ink from the roller.

Ink collection for printers

A printing system includes a printhead; a print drum for transporting print media in the printing system including to the printhead; and a spittoon disposed on the print drum for receiving ink from a spitting operation of the printhead. A method of performing a spitting operation for a printhead includes rotating a print drum with respect to the printhead, where the drum comprises a spittoon disposed on the drum for receiving ink ejected from the printhead during the spitting operation; aligning the spittoon on the drum with the printhead; and spitting ink with the printhead to the spittoon.

Printhead spittoon

Various embodiments of a web are disclosed.

Web apparatus for cleaning arcuate printhead arrangement

Various embodiments of a system and method for spitting are disclosed.

Drum-mounted roller spittoon system and method

Methods and apparatus are provided. Nozzles of a fluid-ejection device of an imaging device adapted to eject a clear fixing liquid are purged by ejecting a number of drops of the clear fixing liquid through the nozzles onto a non-imaging portion of a media sheet.

Purging fixing-liquid ejection devices

Techniques for dispensing a wiper cleaning fluid onto a printhead ink-ejecting nozzles, wherein the fluid is sprayed onto the nozzles, effectively dissolving ink and residue on the surface.

Wiping fluid spray system for inkjet printhead

A snout wiper assembly includes a support member, a supported member and a snout wiper. The support member defines a travel slot. The supported member is movable along the travel slot between positions including a wiping position and a resting position. The snout wiper is carried by the supported member.

Snout wiper assembly

A modular ink absorbent system for channeling waste ink spit from a printhead in an inkjet printing mechanism to a permanent storage location while isolating the ink from contaminating other components in the mechanism. An absorbent core has a spit target that receives the waste ink and an exit surface. A pair of support walls of a flexible or rigid, fluid impervious material sandwich the core between them. The exit surface is in fluid communication with the storage location and the support walls channel the ink from the target surface to the permanent storage location. The support walls have mounting structures which mate easily with mounting structures on the printer service station frame to accurately locate the target from the printhead. A method of conducting ink spit through a printing mechanism, along with an inkjet printing mechanism having such a modular ink absorbent system, are also provided.

Modular ink absorbent system for inkjet spittoons

A spittoon system is provided for an inkjet printing mechanism to handle waste inkjet ink spit from an inkjet printhead during a nozzle clearing, purging or &ldquo;spitting&rdquo; routine. The spittoon system includes a frame defining a spittoon chamber having an entrance mouth, and a chimney passageway extending between the mouth and the chamber. A hard porous plastic liner lines this passageway from the mouth and into the chamber, with the liner material having no troublesome fibers projecting from a spit target platform so the platform can be located closer to the printhead than the earlier fiberous liners. This close spit target to printhead spacing, along with a larger spit target area traps inkjet aerosol and misdirected ink droplets ejected during a spitting routine. A method of purging ink residue from an inkjet printhead, along with an inkjet printing mechanism having such a spittoon system, are also provided.
