  • Patent number: 11491799
    Abstract: A transport section transports a continuous printing paper in a predetermined transport direction. A first print section ejects first ink to the printing paper. A second print section is provided in a downstream side of the first print section in the transport direction, and ejects second ink to the printing paper. An ink amount estimating section estimates an amount of ink ejected to the printing paper from before printing by the first print section to before printing by the second print section, based on print data. A deviation amount obtaining section obtains a deviation amount between a print position by the first print section and a print position by the second print section at least based on the estimated ink amount. A print control section controls the print position by the second print section based on the deviation amount.

  • 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: 11489146
    Abstract: An ink printing process employs per-nozzle droplet volume measurement and processing software that plans droplet combinations to reach specific aggregate ink fills per target region, guaranteeing compliance with minimum and maximum ink fills set by specification. In various embodiments, different droplet combinations are produced through different printhead/substrate scan offsets, offsets between printheads, the use of different nozzle drive waveforms, and/or other techniques. These combinations can be based on repeated, rapid droplet measurements that develop understandings for each nozzle of means and spreads for expected droplet volume, velocity and trajectory, with combinations of droplets being planned based on these statistical parameters. Optionally, random fill variation can be introduced so as to mitigate Mura effects in a finished display device. The disclosed techniques have many possible applications.

  • Patent number: 11479043
    Abstract: Since a head part is arranged in an inclined posture, the ink ejected from a nozzle surface of the head part may drip to a first lower surface peripheral edge portion along the nozzle surface, and then drops from a first long side of a lower surface of the head part toward a first side wall of a cover member being arranged below the head part. The first side wall having an upper end portion is located away from the first long side. Thus, the dropped ink is collected by the cover member without being attached to the upper end portion of the first side wall. Therefore, the ink can be prevented from being solidified at the first lower surface peripheral edge portion and the reattachment of the ink to the nozzle surface can be effectively prevented.
