Techniques for handling and reducing ink overspray of an ink jet printer are provided. In an example, an ink overspray collector for an ink jet printer can include a first opening defining a first print area of the ink jet printer, and a frame about the first opening. The frame is configured to receive overspray from operation of the ink jet printer and can be formed of a woven material. In some examples, a controller of the ink jet printer can reduce an amount of ink ejected near the edges of the print media to reduce overspray.

In a printing apparatus, a platen configured to support a sheet to be printed includes an ink receiver configured to receive ink discharged from a print head. The ink receiver includes a plurality of first ink grooves and a plurality of second ink grooves configured to guide the received ink, the second ink grooves having a tilt angle greater than that of the first ink grooves. The platen includes an absorber configured to absorb the ink received by the ink receiver, the absorber being arranged on a back side of the ink receiver.

A tray includes a holding portion configured to hold a print medium in a predetermined holding area and an ink absorption portion positioned adjacent to the holding area.

A printing apparatus includes a conveyance unit configured to convey a sheet in a conveyance direction, a print unit configured to perform printing on the sheet conveyed by the conveyance unit, a light receiving unit configured to receive light and make an output according to the received light, and a control unit configured to control borderless printing by the print unit, the borderless printing including extra-printing from a sheet edge to outside of the sheet. The control unit sets an extra-printing amount by which printing extends off the sheet edge after the light receiving unit makes the output according to the received light.

A platen includes: a plurality of supporting portions capable of supporting a sheet; negative pressure chambers, to which a negative pressure is supplied, so as to suck a sheet facing the supporting portions to the supporting portions; and ink receiver and that receive ink ejected from a printhead to the outside of the sheet supported by the supporting portions. The plurality of supporting portions are arranged in a sheet width direction (i.e., an X direction) transverse a sheet conveyance direction. The plurality of negative pressure chambers are disposed in a manner corresponding to the plurality of supporting portions, respectively.

A printer includes a printing head and a plurality of recessed portions disposed to oppose the printing head. A depth of each of the recessed portions is larger than a shortest distance of an opening portion of each recessed portion in a planar view. The shortest distance is a width of the opening portion in a view from a medium feeding direction or a width of the opening portion in a view from a moving direction of the printing head.

A platen disposed at a position at which the platen faces a printing head includes a contact portion that comes into contact with a recording medium, a non-contact portion that does not come into contact with the recording medium, and an ink receiving portion that receives ink ejected to beyond the recording medium. A recessed portion is formed between the ink receiving portion and the contact portion in the width direction of the recording medium so as to be lower than the contact portion in the vertical direction. A supply portion that supplies air to the recessed portion is formed upstream of the recessed portion in the conveyance direction of the recording medium.

A platen disposed so as to face a printing head includes a third support portion. A second suction hole is formed in an area through which a recording medium passes at least beyond the third support portion in the width direction of the recording medium or downstream of the third support portion in the conveyance direction. A supply port is formed between the third support portion and the second suction hole. Air is sucked into the second suction hole and supplied toward the recording medium through the supply port.

A recording apparatus discharges an ink in a first color to a position at which an accumulated state on an ink absorber is to be detected. After that, a light is emitted onto the position from a light emitting unit, and reflected light is received by a light receiving unit.

A recessed portion is a portion that is provided to an end of a platen in an X direction and is recessed from the supporting surface of the platen. A discharge portion discharges the ink in the recessed portion along a +Y direction. A width of the discharge portion in an X direction is smaller than a width of the recessed portion in the X direction, and a position of the discharge portion in the X direction is arranged on an inner side with respect to a position of an edge of the roll paper. An end side of the discharge path, which is positioned on an inner side of the roll paper in the X direction, is arranged continuously to an end side of the recessed portion, which is positioned on the inner side of the roll paper, on an extension line of the end side.
