  • Patent number: 11960947
    Abstract: Variable data printing operations use static and variable content to create many different documents. An estimation system for printing operations implements accelerated consumable use estimation for variable data printing operations by tagging reused objects having static content. The static content is rendered within the estimation system once and then stored for use in later estimation operations, as needed. Variable content is rendered for each record. Using this process, the estimation system does not need to render reused content repeatedly in providing consumable use estimates.

  • Patent number: 11586399
    Abstract: A printing system includes a printing device, a color management server, and a client device. An estimated ink use is determined for a print job within printing system. After printing operations, a baseline average ink use is determined for a set of printed pages of the print job. If the baseline average ink use varies from the estimated ink use, then a corrective action is taken to adjust ink use to be closer to the estimated ink use. The corrective action is a global corrective action for the entire document of the print job or a targeted action that adjusts only specified features or pages of the document.

  • Patent number: 11513471
    Abstract: An image forming apparatus includes: a casing having an opening; a cover for opening and closing the opening; a cartridge attachable to the casing through the opening; and a controller. The casing includes a first memory. The cartridge includes a second memory storing consumption state information representing a consumption state of the cartridge. The controller performs: determining whether the cartridge attached to the casing is unused; storing, when the attached cartridge is unused, the consumption state information acquired from the second memory in the first memory; determining, when the image forming apparatus is powered on or the cover is closed, whether the consumption state information in the first memory and the consumption state information in the second memory match; permitting use of the cartridge when the two sets of consumption state information match; and prohibiting use of the cartridge when the two set of consumption state information does not match.

  • Patent number: 11498339
    Abstract: An ink-jet printing apparatus includes an ink-cartridge mounting unit to which an ink cartridge having a first ink chamber containing ink is to be mounted, and a second ink chamber. The second ink chamber stores ink supplied from the first ink chamber. The ink-jet printing apparatus is configured such that, in a case where the ink cartridge is mounted to the ink-cartridge mounting unit, the second ink chamber can be viewed from outside of the ink-jet printing apparatus. An equation 0.5?L?d?1.2 L is satisfied, where d is a length of the second ink chamber, and L is a length of the ink cartridge in a direction in which the ink cartridge is inserted into the ink-jet printing apparatus.

  • Patent number: 11485146
    Abstract: An Imaging device includes a print monitoring engine to monitor an ink level of an ink cartridge installed in the imaging device and track a print count for each ink level. The print count for each ink level indicates a number of prints printed during a one percent drop in the ink level. Further, a print capacity estimation engine is to determine an average print rate for the ink cartridge based on the print count for each one percent drop in ink level and determine a print capacity estimate of the ink cartridge based at least on the average print rate and the current ink level. Further, an Ink cartridge controlling engine is to deactivate the ink cartridge upon occurrence of a predetermined event and activate the deactivated ink cartridge in response to an activation input from a user, wherein the activation input is based on the print capacity estimate.

  • Patent number: 11407221
    Abstract: A printer includes a print head to print a pixel by ejecting drops of a printing fluid from the print head, and a controller. The controller monitors a drop volume of the printing fluid ejected by the print head. When the drop volume is below a threshold, the controller controls the print head in accordance with a first print mode to increase the frequency of ejecting drops of the printing fluid within the pixel print time with a decrease in the drop volume that maintains a print quality parameter. The controller changes to a second print mode to increase the pixel print time that maintains the print quality parameter.
