An image forming device includes a first supplier configured to supply a long recording medium, an image forming engine configured to form an image on the recording medium supplied from the first supplier using a color material supplied from a color reservoir, a remaining amount output device configured to output a signal indicating a remaining amount of the color material. The image forming device derives a length of a recording medium on which images can be formed until a color material in the color reservoir runs out, and displays the length of the recording medium on which the images can be formed derived in the deriving on a display.

Provided is a technique that enables application of additional conveyance force to a print medium and conveyance of various sizes of print media without multi-feed. A conveyance device includes a feed unit, a first conveyance unit that conveys a print medium, and a second conveyance unit that conveys a print medium fed by the feed unit to the first conveyance unit, and is capable of correcting the skew of a print medium by causing the second conveyance unit to convey the print medium with its leading edge in abutment with the first conveyance unit. This conveyance device is configured to cause the feed unit to apply conveyance force to a print medium conveyed by the second conveyance unit, depending on the size of the print medium in the conveyance direction.

An ink-jet recording apparatus includes: an image recorder; a first supporter including support ribs extending to positions under the image recorder; an ink receiver disposed downstream of the support ribs; first and second roller pairs disposed downstream of the first supporter; a guide; and a protrusion disposed between the ink receiver and the first roller pair and having an upper end located below upper ends of the support ribs and above a first imaginary line connecting between a nip position of the first roller pair and a downstream end of the ink receiver. A distance between an upstream end of the ink receiver and a nip position of the second roller pair is less than a length of a first-size sheet and greater than a length of a second-size sheet. The protrusion is disposed, in a widthwise direction, in a region through which the second-size sheet is conveyed.

A recording apparatus includes a plurality of medium containing units that is provided along a vertical direction and contains a medium before recording, a liquid ejecting head that performs recording by ejecting liquid toward the medium, and at least one liquid containing unit that contains the liquid. The plurality of medium containing units includes a first medium containing unit located at an uppermost position, and a second medium containing unit located below the first medium containing unit. A size of the first medium containing unit in a medium feeding-out direction, in which the medium is fed out, is smaller than a size of the second medium containing unit in the medium feeding-out direction, and the at least one liquid containing unit is provided above the second medium containing unit in such a way as to overlap with the first medium containing unit in a vertical direction.

The sheet discharge device includes a sheet discharge port, a discharge member, a sheet discharge tray, a support member, a drive mechanism, and a controller. The discharge member conveys sheets in a discharge direction. On the sheet discharge tray, the sheets discharged from the sheet discharge port are to be stacked. The support member is movable by the drive mechanism between a projective position in which the support member is projected to above the sheet discharge tray so as to support the sheets, and a retractive position in which the support member has retracted from the projective position to an upstream side of the sheet discharge port. The controller is enabled to adjust at least one of a projective length of the support member in its projective position and a shift timing from the projective position to the retractive position in response to characteristics of the sheets.

When discharging a sheet onto a discharge tray, a control unit sets position of the discharge tray in an up and down direction to a predetermined discharge position. When loading the sheet onto a processing tray, the control unit sets the position of the discharge tray in the up and down direction to a loading position lower than the discharge position.

An example method comprises providing a textile on which a printing fluid is to be deposited at a printing station and supporting the textile by a support member. The support member is to advance the textile through the printing station. The example method comprises increasing a dimension of the support member to increase a dimension of the textile, and advancing the textile toward the printing station by advancing the support member toward the printing station.

A method of detecting feeding status and width of paper is disclosed in this present invention, steps of the method include: step a, using at least one infrared light transmitter to transmit infrared light signals; step b, using a light-gathering element to gather together the infrared light signals transmitted by the infrared light transmitter; step c, using a light receiver to receive the infrared light signals gathered together by the light-gathering element, when paper is fed forward, the paper will be located between the infrared light transmitter and the light-gathering element, and will cover a part of the light-gathering element so as to cut off a part of the infrared light signals, how many infrared light signals the light receiver received will be changed, a feeding status and a width of the paper is determined according to how many infrared light signals the light receiver received.

A control apparatus includes a grouping unit configured to divide a plurality of sheets, each associated with a plurality of pages included in a processing target job into groups, and a control unit to control feeding of a sheet from a feeding unit onto a conveyance path and refeeding of a sheet that has been conveyed on the conveyance path onto the conveyance path. The grouping unit sets a group size that is not less than a maximum sheet size used in the processing target job, and the grouping unit decides the group of the predetermined page as the first group. The grouping unit also decides the group of the predetermined page as a second group different from the first group, and the control unit controls feeding and refeeding for each group grouped in the grouping unit.

An image forming system includes a transport section that includes a support surface supporting a sheet-like medium and transports the medium while supporting the medium on the support surface, a first pressure generating section that generates pressure used to suck the medium supported on the support surface, and an image forming section that forms an image on the medium transported by the transport section. First suction holes that communicate with the first pressure generating section, first protrusions, and sealed portions that are disposed at positions where end portions of the medium in the medium width direction are supported and restrict inflow of air to regions, in which the first suction holes are arranged, from the outside of the end portions of the medium in the medium width direction are arranged on the support surface in a medium support region where the medium can be supported.
