An inkjet printer uses ink supply containers that includes bladders for holding waste fluids produced by printhead maintenance stations. The bladders are connected serially or in parallel to the output ports of the printhead maintenance stations to store waste fluids within the bladders of the ink supply containers. As the ink supply containers are depleted of their supply ink, they are replaced and new ink supply containers having bladders within them are installed to renew the capacity of the printer to store waste fluids. In two embodiments, the need for a waste fluid reservoir is eliminated and in a third embodiment, the operational life of a waste fluid reservoir is extended. In all of these embodiments, the production of plastic waste by the printer is reduced.

System and method for reducing plastic waste in inkjet printers

An inkjet printer includes a waste ink treatment system and a humidification chamber to separate waste ink produced by a printhead maintenance station into solid ink pigment particles and a solvent stream and use the solvent stream to maintain inkjets in the printheads of the inkjet printer in operational status. The waste ink treatment system mixes the waste ink with a metal salt to precipitate the solid ink pigment particles out of the waste ink. The solvent stream remaining after the precipitation of the pigment particles is humidified and directed to air baffles positioned on opposite sides of each printhead in every other printhead module in the process direction. A kit is provided to retroactively modify an existing inkjet printer to treat the waste ink and use the solvent stream to maintain the operational status of the inkjets in the printheads of the inkjet printer.

A method of manufacturing a three-dimensional object operates components in an additive manufacturing system with reference to a difference between quantifications identified for different properties of at least two materials in a same layer. The method enables the layer to be formed with compensation for the differences in the quantifications of the properties of the two materials.

An MFD is disclosed. For example, the MFD includes a printhead to dispense print material, an enhancement printhead to dispense an enhancement printing fluid, a processor and a non-transitory computer-readable medium storing a plurality of instructions. The instructions when executed by the processor cause the processor to perform operations that include determining that an automated enhancement feature was selected, analyzing each pixel of an image to be printed to determine one or more pixels that are to receive the enhancement printing fluid, controlling the printhead to print the image, and controlling the enhancement printhead to dispense the enhancement printing fluid on the one or more pixels that are to receive the enhancement printing fluid.

Automated enhancement of printed documents

A method of inkjet printer operation produces a sneeze pattern having a uniform sneeze pattern portion and a tapered area portion within the uniform sneeze pattern to operate inkjets in the printer to eject ink drops within an image area of media sheets passing through the printer to maintain the operational status of the inkjets. A dynamic threshold is applied to a portion of an uniform sneeze pattern to produce the tapered area within the uniform sneeze pattern. The dynamic threshold is changed as a function of distance between a pixel in the portion of the uniform sneeze pattern and the closest edge of an image area of the media sheet on which the tapered area of the sneeze pattern is to be printed. A second threshold can also be changed to alter a volume of ink associated with a pixel in the tapered area within the uniform sneeze pattern.

A printing system comprises an ink deposition assembly and a media transport device. The ink deposition assembly comprises printheads to deposit a print fluid, such as ink, on print media, such as paper. The media transport device holds the print media against a movable support surface, such as a belt, by vacuum suction platen and transports the print media though a deposition region. The vacuum suction is communicated to the movable through platen holes and platen channels in a vacuum platen. At least some of the platen channels have a high impedance region that has a reduced open cross-sectional area as compared to another region of the platen channel.

A color inkjet printer includes an electrode that emits an electric field into a gap between a printhead and a media transport that carries media past the printhead. Image data generated by an optical sensor after an ink image is printed on the media is analyzed to measure at least one image quality metric. When the measured image quality metric is outside of a tolerance range, the voltage of a voltage source electrically connected to the electrode is adjusted to improve the wetting of the media type with the ink ejected by the printhead.

A printing system comprises a print fluid deposition assembly, a media transport device, and an air flow control system. The print fluid deposition assembly comprises a carrier plate and a printhead arranged to eject a print fluid through an opening of the carrier plate to a deposition region. The media transport device holds a print medium against the movable support surface by vacuum suction and transports the print medium through the deposition region. The air flow control system comprises an air supply unit comprising air flow guide structure extending into the opening of the carrier plate between the carrier plate and the printhead to flow air through the opening. The air flow control system controls the air supply unit to selectively flow the air based on a location of a print medium relative to the printhead.

A method of operating a printer extends the print zone of the printer by separating at least two printhead modules in the print zone by a distance that is greater than a width of a printhead module. The printhead modules are operated to print multiple color separations of an ink image and operates an optical sensors generates image data of the printed multiple color separations. The image data of the printed color separations are used to adjust distances between printhead modules in the print zone.

An optical gloss meter above an imaging member surface measures fountain solution surface gloss on the imaging member surface in real-time during a printing operation. The measured gloss corresponds to a thickness of the fountain solution layer and may be used in a feedback loop to actively control fountain solution layer thickness by adjusting the volumetric feed rate of fountain solution added onto the imaging member surface during a printing operation to reach a desired uniform thickness for the printing. This fountain solution monitoring system may be fully automated.

Fountain solution thickness identification via gloss measurement system and method

Apparatus and method for using a line laser (LL) to quickly mark a substrate or media by utilizing a laser additive on/within the substrate/media, which greatly reduces the power requirement for marking the substrate/media. The combination of the LL wide swath (&#x3e;305 mm) and the improved media/surface sensitivity to laser wavelength allows the LL marking system to achieve faster marking than other systems. The LL is mounted over a transport which transports the sensitized substrate/media past the LL for marking. The desired image is projected from the LL line by line in synch with the moving media and once the media passes the beam path of the LL, marking is complete. In this case, the media has been physically-altered via the heat generated by the LL interacting with the photosensitized media and is permanent. A second method would use a photosensitizing agent coated on top of the media to be marked.
