Recording apparatus and method of controlling recording apparatus

A recording apparatus includes a liquid ejection head, where the liquid ejection head includes: an ejection port, a first substrate, and a temperature detection element. The ejection port ejects liquid and includes a protrusion extending toward an ejection port inside. The first substrate includes a heating element that ejects liquid from the ejection port using heat. The temperature detection element detects temperature of the first substrate. Driving of the heating element is controlled based on whether a difference between a voltage value Vp1 measured by the temperature detection element and a preset voltage value Vp01 has a positive value within or outside a predetermined range or a negative value outside the predetermined range. The voltage value Vp1 is measured when a temperature change amount becomes maximum in a temperature falling process of a second substrate located, after the heating element is driven, at a position corresponding to the heating element.

An inkjet recording apparatus includes a heater and a recording head. The heater is disposed upstream of the recording head in terms of a conveyance direction of a recording medium. The recording medium heated by the heater has a temperature of from 40 to 80° C. The ink contains a pigment, a cellulose derivative, first and second water-soluble organic solvents, and water. The first water-soluble organic solvent is glycol ether. The second water-soluble organic solvent is a water-soluble organic solvent that is not glycol ether. The cellulose derivative has a percentage content of from 0.01 to 0.20% by mass relative to the mass of the ink. The percentage content of the glycol ether is from 6 to 24% by mass relative to the mass of the ink and from 20 to 80% by mass relative to the total mass of the first water-soluble organic solvent and the second water-soluble organic solvent.

A cleaning method of a liquid ejection head where recording element substrates having an ejection orifice forming-face having ejection orifice arrays which are aligned, and at least one array ejects a different recording liquid than another, includes wiping and preliminary ejection. In the wiping, a wiping member is caused to move along and wipe the arrays. In the preliminary ejection, before the wiping of the entire ejection orifice forming-face is completed, preliminary ejection from the wiped ejection orifices is started. The wiping and preliminary ejection are sequentially performed from a recording element substrate at one end to a recording element substrate at the other end.

20220371325 · 2022-11-24 ·

A printing device includes: an inkjet printhead having a row of ink ejection devices; a lift mechanism configured for raising and lowering the printhead between a maintenance position and a printing position; a conveyor tape positioned below the printhead in the printing position, the conveyor tape defining a slot aligned with the row of ink ejection devices; and a tape movement mechanism for moving the tape longitudinally along the length of the printhead. The tape movement mechanism is configured to move the tape along the printhead during printing, thereby conveying condensate accumulated on an underside of the tape away from the printhead.

SYSTEM AND METHOD FOR DETECTING AND REMEDIATING SPLIT INKJETS IN AN INKJET PRINTER DURING PRINTING OPERATIONS
20220371348 · 2022-11-24 ·

A method analyzes image data of a test pattern printed on an image receiving member by a printer to identify split inkjets in the printheads of the printer. The test pattern is formed by operating each inkjet of a printhead to form a dash and the areas of the dashes are compared to an average dash area to identify split inkjets. Firing signal parameters for the split inkjets are adjusted and subsequent firing signals are generated using the adjusted parameters. Image data of the pixels formed by the split inkjets are analyzed after the split inkjets have been operated using the adjusted firing signal parameters. If the pixel size for a split inkjets indicates that the split inkjet has been remediated, then the firing signal parameters are returned to their nominal values.

Discharge apparatus and suction unit

A discharge apparatus includes a discharge unit configured to discharge a liquid to a medium, a suction unit, and a supply unit configured to supply a gas to the suction unit. The suction unit includes an opening facing the medium, and a suction groove including an arc-shaped inner wall surface inside the opening and configured to suck mist around the medium. An outlet portion configured to blow out the gas supplied from the supply unit toward the inner wall surface is provided in the opening.

Inkjet recording device

An inkjet recording device has a head base, a head unit, and an adjustment mechanism. The adjustment mechanism has a guide screw, a moving member, the operation member for rotating the moving member, and an adjusting member. The moving member has a shaft hole screwed into the guide screw, and moves in an axial direction of the guide screw by rotating with respect to the guide screw. The adjusting member has a first contact portion in contact with the moving member and a second contact portion in contact with the head unit. The second contact portion moves in a direction toward the head unit and a direction away from the head unit, by moving the moving member in contact with the first contact portion in the axial direction of the guide screw.
