Provided are systems and methods for identifying, isolating, and/or aligning sheets. An identification system can facilitate accurate identification of a sheet by (i) vacating one or more components of the system that are not the sheet from a zone of detection, and/or (ii) determining a reference axis of the sheet. An isolation system can facilitate accurate isolation of a sheet by (i) providing targeted air flow, and/or (ii) introducing a wave into the sheet. Identification systems and/or isolation systems described herein may facilitate isolation of sheets that were previously fastened together by one or more fasteners. An alignment system can facilitate accurate alignment of a first sheet at an upstream location relative to a second sheet at a downstream location via machine learning.

In an example, a conditioner module may include a bridge to receive media from a media path of an imaging device and to deliver the media to a media input of a finisher module. The conditioner module may include a calender nip disposed at an output end of the bridge. The calender nip may compress the media and may feed the media into the media input of the finisher module.

A motor control unit controls a driving current that flows through a coil of a motor to be driven, by controlling a PWM signal supplied to an H bridge circuit constituted by FETs. A current value generation unit detects a driving current based on a voltage that occurs across a current detection resistor, and corrects a detection value by using a first or second correction value. The current value generation unit, if the driving current is detected in the H period of the PWM signal, corrects the detection value by using the first correction value, and if the driving current is detected in the L period of the PWM signal, corrects the detection value by using the second correction value that has a polarity different from a polarity of the first correction value.

An image forming apparatus includes a conveyor configured to convey a sheet along a conveyance path, a communication interface, and a controller. The wireless tag communication device is configured to wirelessly communicate with a wireless tag of the sheet. The controller is configured to read, by the communication interface, first data from the wireless tag of the sheet on the conveyance path. The controller is configured to compare the first data with second data.

An image forming apparatus includes: an image former that forms an image on a recording medium; a slip sheet inserter that inserts a slip sheet; and a hardware processor capable of controlling image formation, slip sheet insertion and post-processing, wherein the hardware processor acquires a read image obtained by reading the recording medium on which the image is formed and determines whether an abnormality is present in the image on the recording medium based on the read image, and when detecting the abnormality in the image on the recording medium of a page to which bundle post-processing to bundle recording media as one bundle is applied, the hardware processor performs control to discharge the slip sheet after producing a bundle including the recording medium by the bundle post-processing without inserting the slip sheet.

The present invention is related to a scanning device for scanning documents, comprises a flat-bed scanning glass; a contact image sensor arranged above the flat-bed scanning glass separately to form a scanning path therebetween, a bottom surface of the contact image sensor being arranged with a protecting glass, a middle area of the protecting glass being configured as a scanning area, and a chamfer being arranged at the bottom surface of the protecting glass at a downstream position relative to the scanning area. Hence the dust of documents in this invention would be stacked in the chamfer during the scanning process temporarily and then be wiped away by the document itself, so as to assure the dust would not be stacked in the scanning area. The scanning device in this invention is capable to maintain the scanning quality without clearing the dust even after scanned a massive quantity of documents.

A sheet feeding sub tray is detachably attachable to a sheet loading stand of a sheet conveying device that includes a setting reference part on one end side of the sheet loading stand in a sheet width direction. The sheet feeding sub tray includes a small-size setting reference part disposed at a position closer to a center of the sheet loading stand in the sheet width direction than the setting reference part in a state in which the sheet feeding sub tray is installed to the sheet loading stand.

An image reading apparatus includes a shooter where a first mounting surface that is inclined with respect to a horizontal plane is formed thereon, a stacker, a supporting unit that movably supports the stacker in such a manner that the stacker is arranged in a first region or a second region, a conveyance unit that conveys a document from the shooter to the stacker when the stacker is arranged in the first region, and a reading unit that reads an image from the document when the document is conveyed by the conveyance unit, wherein a surface area of a region of the first mounting surface that is covered by the stacker when the stacker is arranged in the first region is greater as compared with that when the stacker is arranged in the second region, and the stacker is formed to be capable of being lengthened or shortened.
