Inkjet printing apparatus and determining method

An inkjet printing apparatus includes a print head that ejects ink, a waste ink tank having an absorber that absorbs ink discharged from the print head. The inkjet printing apparatus further includes a counting unit that counts a waste ink amount discharged to the waste ink tank, a timer that measures an elapsed time from installation of the waste ink tank in the apparatus, an acquiring unit that acquires a waste ink retention amount by obtaining an evaporation amount from evaporation of waste ink retained in the waste ink tank based on the elapsed time and subtracting the evaporation amount from the waste ink amount, a notifying unit that notifies that the waste ink retention amount exceeds a threshold; and a setting unit that sets the threshold based on a waste ink evaporation rate calculated by using the evaporation amount and the waste ink amount.

Inkjet printing apparatus and method of controlling inkjet printing apparatus

An inkjet printing apparatus is provided with a tank that stores ink, a print head that performs print operation by ejecting ink supplied from the tank, a circulation unit that establishes a circulating state to circulate ink in a circulation path if print operation is performed and establishes a stopped state to stop circulation of ink if print operation is terminated, and a deaeration unit that performs deaeration operation to deaerate ink inside the circulation path. The apparatus includes an estimation unit that estimates a dissolved gas amount in ink inside the circulation path based on dissolved gas amounts increased in the circulating state and in the stopped state, respectively, and a control unit that causes the deaeration unit to execute deaeration operation after completion of print operation if the dissolved gas amount estimated by the estimation unit exceeds a predetermined threshold.

RECORDING APPARATUS AND METHOD FOR SUPPRESSING DEVIATION OF RECORDING POSITION OF RECORDING APPARATUS

A recording apparatus includes a cassette or a feeding tray that is configured to mount a medium thereon, a transport unit that transports the medium mounted on the cassette or the feeding tray, and a recording head that performs recording on the medium. Furthermore, the recording apparatus includes a medium detection device and a deviation amount acquisition section. The medium detection device detects at least one of both side edges in a width direction intersecting a transport direction of the medium that is transported from the cassette or the feeding tray (step S12). The deviation amount acquisition section acquires a deviation amount of the recording head in the width direction of the medium based on at least one side edge detection position detected by the medium detection device (step S13).

Method for creating a print control profile for printing on a contoured axially symmetric object

A process is disclosed for creating a print profile to control the operation of a direct-to-shape printing system for applying images on the exterior of an axially symmetrical media object that has a contoured, varying exterior surface, such as occurs on curved wine bottles and sports equipment like bats. The process takes a media recipe holding media geometry information and an image intended to be printed and processes that information to control a motion control subsystem and a print engine subsystem. The geometry information is manipulated to generate a CAM table suitable for the motion control subsystem, and the image file is processed to create a raster image file suitable for ink head expression. Various setup values are included in the process to prepare the direct-to-shape printing system for use of the media recipe.

Printing apparatus, control method, and non-transitory computer-readable storage medium

A printing apparatus includes a conveyance unit including a pair of rotation members that nip a roll sheet, and configured to convey the sheet by rotation of the pair of rotation members, a printing unit, and a control unit configured to, upon executing a new print job, cause the conveyance unit to perform a preparatory operation in which the sheet is conveyed in a forward direction and then conveyed in a reverse direction and stopped. If a predetermined condition is met after completion of a previous print job, the control unit causes the conveyance unit to perform the preparatory operation, and if the predetermined condition is not met after completion of a previous print job, the control unit does not cause the conveyance unit to perform the preparatory operation.

Pressure diffrentials at printers

An example method comprises identifying, by a processor, a gap in a housing of a printing apparatus and positioning an inlet of a conduit inside the housing proximate the gap. The inlet is fluidly connected to a fan, and the fan is powered to create a pressure differential across the housing to minimize the amount of air inside the housing being able to escape the housing via the gap.
