  • Patent number: 11483442
    Abstract: A method is disclosed. For example, the method executed by a processor of a multi-function device (MFD) includes monitoring operating parameters of a component in the MFD, calculating a life set point for the component based on the operating parameters, and changing a default life set point for the component stored in a memory of the MFD to the life set point that is calculated based on the operating parameters.

  • Publication number: 20220305815
    Abstract: 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 comprises a movable support surface to transport a print medium along a process direction through the deposition region, the media transport device holding the print medium against the movable support surface by vacuum suction. The air flow control system is arranged to selectively flow air through the opening of the carrier plate between the carrier plate and the printhead based on a location of a print medium transported by the media transport device relative to the printhead.

The print fluid deposition assembly comprises a printhead to eject a print fluid through an opening of a 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 is to flow air through the carrier plate to the movable support surface via a port through the carrier plate on an inboard side the carrier plate and to control a flow rate of the air flowed through the port based on a size of a print medium transported by the media transport device.

  • Patent number: 11198580
    Abstract: An apparatus is disclosed. For example, the apparatus includes a paper feed to feed print media a single sheet at a time, a plurality of rotating discs, wherein each one of the plurality of rotating discs comprises an elastomer ring to secure a leading edge of the single sheet against a registration wall and initiate a flipping process, a curved baffle positioned above the plurality of rotating discs and the single sheet, an air duct located above the plurality of rotating discs and the single sheet to force an air flow towards the curved baffle, wherein the air flow follows a shape of the curved baffle to create a low pressure zone above the single sheet to keep a trailing edge of the single sheet levitated during completion of the flipping process, and a movable platform to hold a stack of the print media.

  • Patent number: 11188013
    Abstract: An apparatus for stripping light weight and ultra-light weight media from a photoreceptor that is tacked thereto by electrostatic or vacuum force includes a set of low-tip stripper fingers configured to strip the light weight and ultra-light weight media from the photoreceptor. The low-tip stripper fingers are adjustable both in the cross process and in attack angle with respect to the photoreceptor in order to change the height at which the tip of each stripper finger is in relation to the photoreceptor and thereby prevent jams due to miss-strips. Additionally, dual stripper fingers are disclosed that support inboard and outboard edges of larger media in order to reduce dog ears and jams.

  • Patent number: 11117774
    Abstract: A system for controlling curl in sheets passing beneath a camera includes applying a thin layer of high velocity air to a curved baffle positioned beneath the camera. The high velocity air layer, which will have a tendency to follow the curved baffle (Coanda effect), will divert sheets (Bernoulli effect) towards the curved baffle. By positioning the curved baffle along the media paper path and by applying a uniform air stream to it, a lower pressure area will be created. This will flatten the trajectory of the sheets and thereby remove curl before the sheets pass the camera.

  • Patent number: 11046544
    Abstract: An apparatus for controlling cross curl in corners of sheets between in-line transports includes a curved baffle placed between the two transports. A thin layer of high velocity air is applied to the curved baffle only at lead edge corner regions of the sheets. The high velocity air layer, which will have a tendency to follow the curved baffle (Coanda effect), will divert corners of the sheets (Bernoulli effect) towards the curved baffle. By positioning a curved baffle between the two transports and by applying a uniform air stream to it, a lower pressure area will be created. This will flatten the corners of the sheets and ensure passage between downstream baffles and acquisition by a downstream transport.

  • Patent number: 10836189
    Abstract: A movable cleaning web can be positioned and allowed to move from a supply spool, between a platen (e.g., vacuum, marking) and the inside of a belt (e.g., marking, transport), into a take-up spool. The cleaning web can move opposite the process direction of the belt. The web can reduce contamination on the platen, inside of belt and along belt rollers.
