A liquid droplet ejecting apparatus includes a medium supporting portion that moves in a transport direction in a state of supporting a medium; a liquid droplet ejecting portion that ejects liquid droplets (ink droplets) onto an ejection area of the medium supported by the medium supporting portion; a detection portion that detects a light amount of reflected light of light having been emitted toward the medium supporting portion or the medium supported by the medium supporting portion; and a carriage that reciprocates in a width direction intersecting the transport direction, in a state of supporting the liquid droplet ejecting portion and the detection portion, and a reflection pattern constituted of a high reflection portion having a high reflectance and a low reflection portion having a low reflectance which are repeatedly arranged in the width direction is formed on the medium supporting portion.

An inkjet recording apparatus configured to perform recording operation by ejecting ink at least from a first recording head, includes an ink tank configured to contain the ink to be supplied to the first recording head, a tube configured to connect the first recording head and the ink tank, and a carriage including a first mounting portion on which the first recording head is mounted, a second mounting portion on which a second recording head is detachably mounted, and a contact portion electrically connected to the second recording head, and configured to reciprocate. A protection member protecting the contact portion can be detachably mounted on the second mounting portion.

A liquid discharge apparatus includes a conveyance roller, a liquid discharge head, and a control device. The control device controls the head to discharge liquid onto a medium X times in the main scanning direction and Y times in the sub-scanning direction and controls the roller such that a position of a droplet on the medium discharged by an m-th discharge and a position of another droplet on the medium discharged by an (m+Y)-th discharge are same in the sub-scanning direction, where m is an integer not smaller than one and not greater than ((X−1)×Y). Where P is a circumferential length of the roller and L is a difference in a conveyance distance in the sub-scanning direction when the m-th discharge is compared with the (m+Y)-th discharge, the following relation is satisfied:
L=(n+(Δθ/2π))×P, where |π−Δθ|<60° and n is an integer.

An inkjet printing apparatus includes: a print bar unit including an inkjet head configured to eject ink to a web being conveyed; and a guide configured to guide movement of the print bar unit in a print bar movement direction intersecting a conveyance direction of the web between a first position, a second position, and a third position. The first position is a position where the print bar unit performs printing on the web. The second position and third position are located on one and the other sides of the first position in the print bar movement direction.

A printing apparatus includes a printing head configured to eject ink onto a medium based on print data, a carriage that is mounted with the printing head and that is configured to reciprocate along a main scanning direction, a control unit configured to control the carriage and the printing head and execute a pass corresponding to ink ejection of the printing head along with movement of the carriage, and a colorimetric unit configured to measure density on the medium when the pass is completed.

A print module includes: a body housing first and second opposed printed circuit boards (PCBs), each of the first and second PCBs having heat-generating electronic components; an air inlet and an air outlet positioned towards an upper part of the body; an air pathway extending between the air inlet and the air outlet; a plurality of heatsinks, each heatsink being thermally coupled with one of the heat-generating components and having an array of cooling fins extending into the air pathway; and an inkjet printhead receiving power and print data from at least one of the first and second PCBs. The inkjet printhead is positioned toward a lower part of the print module.

A printer includes a printing unit, a casing, a scanner unit disposed in an upper portion of the casing, and a discharge unit that, below the scanner unit, is connected to the casing pivotably between a closed position and an open position and that a sheet of paper is discharged to. The discharge unit includes a placement surface for the sheet and a medium support unit capable of supporting the sheet from below while in a state of being protruded from the placement surface. The medium support unit is displaceable between a maximum protruded position and a minimum protruded position. When the amount of protrusion of the medium support unit from the placement surface when the discharge unit is in the open position is less than the amount of protrusion of the medium support unit in the maximum protruded position from the placement surface.

A recording device includes a carriage that has a recording head that performs recording on a medium and a plurality of liquid cartridges that house a liquid to be ejected from the recording head, the plurality of liquid cartridges being arranged in a line in a direction that intersects the movement direction of the carriage and being provided with target detection units, and a detector that includes a moving part which moves in a direction that intersects the movement direction of the carriage and that, by the movement of the moving part, detects the residual amount of the liquid between the detector and each of the target detection units of the plurality of the liquid cartridges.

A printing control method, a printing control device and a storage medium are provided. The method includes steps of: acquiring first scan times of first ink used for printing a unit area; acquiring second scan times of second ink used for printing a unit area; comparing the first scan times with the second scan times; according to a comparison result, controlling a printer to eject the first ink or/and the second ink in each scan in a main scan direction. The method and device are able to efficiently and quickly print a three-dimensional effect image.

A carriage includes: a base plate; a liquid jet head including a support plate attached to the base plate; a first engagement portion formed on one end in a Y direction of the support plate; a fixing tool for positioning and fixing the support plate with respect to the base plate, the fixing tool being fixed to the base plate slidably in an X direction by screws and engaged with the first engagement portion; and a flat spring portion that presses the fixing tool toward the base plate. The fixing tool allows movement in the Y direction of the first engagement portion with respect to the fixing tool, and restricts movement in the X direction of the first engagement portion and movement in a thickness direction of the base plate of the first engagement portion with respect to the fixing tool.
