In a printer, a controller controls a printing portion to execute a sample print to print on a sheet a plurality of barcodes. Each of the plurality of barcodes is represented by a received barcode data and printed in a different printing condition. The controller controls a reading portion to read the plurality of barcodes printed on the sheet in the sample print process to obtain a plurality of sets of scan data corresponding to respective ones of the plurality of barcodes. The controller performs a quality determination process to determine qualities of the plurality of printed barcodes based on the respective ones of the plurality of sets of scan data, and a printing condition setting process to set a printing condition based on the qualities determined in the quality determination process. The set printing condition is to be used to print a barcode by the printing portion.

A first surface of a first sheet has a second image formed in advance. An image forming system generates reference data based on a result of reading an image on the first surface of the first sheet on which a first image is not formed, generates first image data that represents a result of reading an image on the first surface of the first sheet having the first image formed on the first surface, and determines, based on the reference data and the first image data, a relative position between the first image and the second image on the first surface of the first sheet.

Provided is a sheet conveying apparatus that includes a conveying unit capable of changing its posture through rotation, and forms a sheet conveyance path capable of conveying a sheet without fail regardless of which posture the conveying unit is in. A first conveying unit is capable of being in a first posture and in a second posture by rotating from the first posture. In a case where the first conveying unit is in the first posture, a sheet conveyance path is formed in which the first conveyance path, the second conveyance path, and the third conveyance path are connected in this order. In a case where the first conveying unit is in the second posture, a sheet conveyance path is formed in which the first conveyance path and the third conveyance path are connected in this order.

A medium transport apparatus includes a main body that is switchable between a first posture and a second posture and a rotatable route-forming member that forms an exterior of a turning route. The route-forming member couples a first transport route to a second transport route when the main body has the first posture and couples the first transport route to a third transport route when the main body has the second posture. The medium transport apparatus further includes a transport route switching section having a switching member that engages with both the body support and the route-forming member. In response to switching between the first posture and the second posture of the main body, engagement of the switching member with the main-body support changes to rotate the route-forming member and to switch the medium transport route to which the first transport route is coupled.

A reading device and an image forming apparatus. The reading device includes a reader disposed at a scanning position, the reader being configured to read an image formed on a surface of a sheet, a movement mechanism to move the reader between the scanning position and a separated position away from the scanning position, and a reference plate disposed at a first position facing a reading face of the reader, the reference plate being configured to obtain a reference value to be used when the reader reads the image. In the reading device, the reference plate rotates around an axis from a second position facing a side of the reader to the first position or from the first position to the second position in conjunction with movement of the reader from the scanning position to the separated position by the movement mechanism The image forming apparatus includes the reading device.

An image reading device includes a tray, a paper feed roller that conveys a sheet, a first sensor that detects a front end and a rear end of the sheet, a second sensor that detects the front end of the sheet, and a scanner that reads an image on a front side of the sheet and reads an image on a back side of the sheet. A controller determines a first time duration that elapses from the detection of the front end of the sheet by the first sensor to the detection of the rear end of the sheet by the first sensor and operates the scanner to read the image on the back side of the sheet over a second time duration equal in length to the first time duration. The second time duration begins after the front end of the sheet is detected by the second sensor.

Method and systems of automated document processing described herein include activating in sequence a plurality of illumination modules of an illumination source to illuminate a document, where the plurality of illumination modules are located at different positions relative to the document. The document can be imaged each time the document is illuminated by an illumination module to provide a plurality of images. A shadow profile of the document can be obtained based on the plurality of images. One or more of a boundary of the document and presence of a fastener attached to the document can be identified using the shadow profile. Any fasteners present may be removed using a robot arm.

An information processing apparatus, an information processing method, and a storage medium that execute density characteristics acquisition processing at an appropriate timing are provided.

A sheet feeding device includes a roller pair being mutually non-separable; and a roller pair being mutually separable. The sheet feeding device temporarily stops a sheet in a registration position of the non-separable roller pair and then resumes feeding the sheet. The sheet feeding device feeds sheets such that a following sheet reaches the registration position from the separable roller pair after completion of ejection of a preceding sheet.

A control unit is capable of selectively executing a first mode and a second mode, the first mode being a mode in which a plurality of sheets having different sizes including a non-standard size are fed by the feeding unit, and the second mode being a mode in which a plurality of sheets having different sizes including only standard sizes are fed by the feeding unit. If the detection unit detects a sheet in a state where the supporting portion is located at the second position and the first mode is selected, the control unit waits for an instruction to start sheet feeding without causing the lifting unit to lift the supporting portion to the first position, and causes the lifting unit to lift the supporting portion to the first position in response to the instruction to start sheet feeding.
