Extracting, as a candidate printing medium and based on the acquired measurement result and the acquired characteristic reference range, a type of printing medium using the characteristic reference range including the measurement result and notifying information indicating the type of the candidate printing medium are performed. The input unit inputs information, wherein a type of printing medium on which recording is to be performed by the recording unit has a first reference range which is the characteristic reference range of the type and corresponds to the input information. The extension unit extends the first reference range.

An image forming apparatus includes a double-sided image forming portion capable of forming an image on each of first and second recording surfaces of a recording sheet, a double-sided image reading portion configured to acquire a pair of divided images each constituting a half of an original image, and an image forming control portion configured to supply a folded recording sheet folded in half to the double-sided image forming portion, and cause the double-sided image forming portion to perform processing of forming the pair of divided images on the first and second recording surfaces, respectively, of the folded recording sheet.

A method of controlling an image forming apparatus having an image reading unit capable of conveying and reading a plurality of documents of different sizes includes determining whether an automatic magnification function is set in a case where an instruction to read a plurality of documents of different sizes is given, and performing control such that, in a case where the determining determines that the automatic magnification function is not set, a first document reading mode in which the plurality of documents is conveyed at a constant conveyance speed and is read is set to the image reading unit, and, in a case where the determining determines that the automatic magnification function is set, a second document reading mode in which the plurality of documents is conveyed at a different conveyance speed for each document and is read is set to the image reading unit.

An apparatus according to the aspect of the embodiments includes a phase determiner configured to determine a rotational phase of a rotor, a speed determiner configured to determine a rotational speed of the rotor, a controller having a first control mode for controlling the motor by supplying constant currents to windings, and a discriminator configured to discriminate whether a rotation of the motor is abnormal based on the rotational speed when the rotational speed corresponding to a command speed is equal to or higher than a predetermined value in a state where the controller is controlling the motor in the first control mode. When a signal output from the discriminator indicates that the rotation of the motor is abnormal, the controller stops the motor. When the signal output from the discriminator indicates that the rotation is not abnormal, the controller continues a drive of the motor.

An image reading apparatus includes an image reading portion; a main assembly; a rotatable member; a damper unit mounted to either one of the main assembly and the rotatable member and including a cylinder portion and a piston portion inserted into the cylinder portion, wherein the damper unit is expanded in an expansion direction and contracted in a contraction direction by sliding the cylinder portion and the piston portion relative to each other; and a contact portion provided on the other one of said main assembly and said rotatable member and configured to contact said damper unit, wherein the damper unit suppresses a speed of said rotatable member when said rotatable member lowers from an upper position toward a lower position in a state in which the contact portion contacts and presses the damper unit in the contraction direction.

In a reading device, a controller performs: detecting occurrence of a double-feed; executing a double-feed process; detecting a state of double-fed sheets; executing a first process when a command is inputted; and executing a second process when the command is not inputted. The double feed process includes: halting conveyance of an original document; and making notification of the occurrence of the double-feed. The first process performs, in accordance with the command, one of: resuming the conveyance of the original document; and quitting the conveyance of the original document. The second process performs, in accordance with a determination result, one of: resuming the conveyance of the original document; and continuing the halting and the making. The resuming is performed when the determination result indicates that the conveyance of the original document is possible. The continuing is performed when the determination result indicates that the conveyance of the original document is impossible.

Various embodiments disclose a method for operating a printer apparatus that includes a print head. The method includes causing a media hub to retract a media in a retract direction along a media path. Further, the method includes causing a first media sensor to generate a first signal during retraction of the media. Furthermore, the method includes monitoring the first signal to detect at least one of a leading edge or a trailing edge of a label of the plurality of labels. Upon detecting the at least one of the leading edge or the trailing edge of the label, causing the media hub to retract the media by at least a predetermined distance, wherein the predetermined distance is a distance between the print head and the first media sensor.

An image reading device includes a tray having a document, first and second rollers, a reading unit to read a document image of the conveyed document at a reading position, and a controller to selectively execute first and second controls. In the first control, the controller changes a drive speed of the first and second rollers from a first to a second speed faster than the first speed after the document reaches the first roller and before the document passes through the reading position, and changes the first and second rollers drive speed from the second to the first speed after the document reaches the second roller and before the image is completely read. In the second control, the controller maintains the first and second rollers drive speed in a section from a position where the document reaches the first roller to a position where the image reading completes.

An image forming device and a sheet conveyance method are provided. An image forming device includes a feeder, a first conveyor, a second conveyor, and a conveyance controller. The feeder aligns a sheet and feeds the sheet to a transfer system that transfers an image to the sheet. The first conveyor is arranged at a first position on an upstream side of the feeder in a sheet conveyance direction and conveys the sheet to the feeder. The second conveyor is arranged at a second position on an upstream side of the first conveyor in the sheet conveyance direction and conveys the sheet to the first conveyor. The conveyance controller performs high-speed control for causing a conveyance speed of the second conveyor to exceed a conveyance speed of the first conveyor when a specific sheet different from a normal sheet is fed by the feeder.

A control device includes a processor configured to: instruct a document reading apparatus that reads a document at a first speed to read image data of the document; and control an image output device that outputs an image to a medium at a second speed higher than the first speed such that the image data of the document starts to be outputted to the medium after reading is started and after a wait time depending on a position at which an additional image starts to be composited when it is determined that reading is finished has elapsed.
