An image forming apparatus executes an image forming operation adequately while reducing a cumbersome work of a user of setting the sheet size. A processor of the image forming apparatus controls an image forming portion to form the image on the sheet even if the sheet size included in an image forming job is inconsistent with the sheet size stored in a storage portion. In such a mode, the processor controls a notification portion so as to give notification when a size detection portion detects one of regular sheet sizes and where the sheet size included in the image forming job is inconsistent with the detected sheet size.

A recording medium feed apparatus includes a manual feed unit, a first detection unit configured to detect a first size corresponding to a size in a first direction of a recording medium placed on the manual feed unit, a second detection unit configured to detect a second size corresponding to a size in a second direction of the recording medium placed on the manual feed unit, the second direction being different from the first direction, a memory configured to store priority setting information, which is to be preferentially used for the recording medium feed apparatus, and circuitry configured to estimate at least one candidate size of the recording medium based on the first size, the second size, and the priority setting information, and to display the at least one candidate size, on a display, as a candidate size of the recording medium.

A printer having a single-sheet manual feed tray improves user convenience. A printer configured to print based on print request data has a manual paper feeder in which only one sheet of print media can be loaded at one time; another paper feeder in which multiple sheets of print media can be loaded at one time; and a manual feeder priority function that prioritizes using the manual paper feeder over the other paper feeder when automatic paper feeder selection is specified in the print request data.

An image forming apparatus includes plural first transfer units, a second transfer unit, a first transport unit, and a drive unit. The first transfer units transfer an image formed on plural image holding units to an intermediate transfer unit. The second transfer unit transfers the image, which is transferred to the intermediate transfer unit, to a recording medium. The first transport unit transports the recording medium to the second transfer unit. The drive unit drives the intermediate transfer unit with at least some of the plural first transfer units separated from the intermediate transfer unit and with the second transfer unit contacting the intermediate transfer unit when the recording medium, which has been subjected to a transport failure, is transported to a feeding position by the first transport unit.

A sheet conveyance apparatus includes a first guide provided in an apparatus body, a second guide provided in an openable portion, a flag member supported by the apparatus body pivotally, a detection unit configured to detect pivoting of the flag member, and a jam release guide provided in the apparatus body. In a state where the openable portion is open, the flag member is protruded into a space that is created between the openable portion and the apparatus body by an opening operation of the openable portion. The jam release guide is disposed at a position not hampering conveyance of the sheet in a state where the openable portion is closed, and is disposed to come in contact, together with the flag member, with a jammed sheet to regulate a posture of the jammed sheet in a state where the openable portion is open.

Disclosed is a sheet feeding apparatus including a tray unit capable of stacking a sheet at an opened position; a feeding member which feeds the sheet stacked on the tray unit; a feed supporting portion which supports the feeding member such that the feeding member is capable of moving to a feeding position for feeding the sheet stacked on the tray unit and to a storage position at which the feeding member is stored in the apparatus main body; and an urging portion which urges the feeding member toward the feeding position, wherein the feed supporting portion includes an abutting portion which abuts against a region other than a sheet stacking region of the tray unit for moving the feed supporting portion and for moving the feeding member to the storage position when the tray unit moves from the opened position to the closed position.

A sheet holder includes a regulator, a rotary body, a detection target, a rotational position detector, and a biasing body. The regulator moves in directions to approach and separate from an end portion of a sheet. The rotary body has a contact portion and rotates according to movement of the regulator. The detection target is attached to the rotary body, has a contact target portion, and rotates together with the rotary body by contacting of the contact portion of the rotary body with the contact target portion of the detection target in a rotational direction of the rotary body. The rotational position detector detects a rotational position of the detection target. The biasing body applies a biasing force between the rotary body and the detection target to maintain a contact state of the contact portion of the rotary body and the contact target portion of the detection target.

A tray drawer and a multi-function printer using the same are provided. The tray drawer includes a drawer body, a tray and an indicating mechanism. The tray is disposed within the drawer body. The indicating mechanism includes an indicator and a linkage. The linkage pivotally connects the indicator and a lateral surface of a front end of the tray.

The present invention is to provide a configuration facilitating removal of a sheet stopped on a conveying belt. In a sheet conveying apparatus that conveys a sheet using a conveying belt and balls, a sheet may be jammed and stopped on the conveying belt. In this case, it is difficult for a user to take out the sheet through a take-out port if the sheet is nipped by conveying roller pairs disposed upstream and downstream relative to the conveying belt in a sheet conveying direction. Thus, conveying roller pairs and the conveying belt are operated such that the sheet, which is stopped on the conveying belt and hence should be taken out through the take-out port, is brought into a state of being nipped only by the conveying belt and balls.

An image forming apparatus includes an image scanning device, which comprises: a document tray to load an original document to be scanned; a discharge tray to load the original document after being scanned; and a frame which the document tray and the discharge tray are mounted on. A conveyance path is formed inside the frame to connect the document tray and the discharge tray. The frame contains a conveying structure to convey the original document along the conveyance path; a transparent support member located below the conveyance path to support the original document; a scanning member located below the transparent support member, the scanning member having a scanning position in which the scanning member scans the original document when being located on the transparent support member; and a pressing member disposed above the transparent support member and facing the scanning member for pressing the original document onto the transparent support member.
