A multifunctional printer comprising a printer section, an auto-document feeder, a scanner section, and a finisher, wherein a finisher path leads from the auto-document feeder into the printer section and converges with a print path into a shared finisher path leading to the finisher, such that documents scanned with the auto-document feeder can be conveyed to the finisher such that it can perform a finishing operation on the documents.

In some examples, a sheet processing machine includes an at least one pile formation device. The at least one pile formation device is arranged so as to be displaceable at least in an inward-moving direction. The at least one pile formation device includes a plane. The at least one pile formation device is displaceable at least in a vertical direction relative to at least one lower multiple-up separating tool by means of a lifting device. In a temporary storage position, at least the plane is arranged in a vertical direction beneath a plane of the at least one lower multiple-up separating tool.

A sheet feeding apparatus includes a sheet stacking portion, a lift plate, an actuating segment, driving unit, a sheet feeding portion, a first detecting portion, a remaining amount detection portion. The remaining amount detection portion includes a detection piece, a link mechanism, a second detecting portion, a controller. The link mechanism couples together the driving shaft and the detection piece at a coupling position attained by pivoting the lift plate through a predetermined angle from a lower limit position in rotation direction, so as to let the driving shaft and the detection piece rotate together. The second detecting portion senses whether or not the detection piece is present. The controller determines the remaining quantity level of the stacked sheets according to whether or not the second detecting portion is detecting the detection piece being present.

A substrate handling system including an infeed system for feeding stacked substrates and including a processing machine for processing stacked substrates, and in particular a printing press for printing stacked substrates. A robot cell is provided between the infeed system and the processing machine. The robot cell comprises one or two gripper systems, each for handling a plurality of substrates. The robot cell is configured in such a way, that selectively differently stacked substrates, which are feedable by the infeed system, can be handled.

A corrugated board plant includes a corrugated board production assembly for producing a double-face laminated web of corrugated board, and at least one cutting assembly arranged downstream of the corrugated board production assembly, which has a cross-cutting device for producing sheets from the double-face web of corrugated board, and is capable of producing at least one identification sheet from the double-face laminated web of corrugated board, which is different from the sheets. The corrugated board plant further has a stack depositing area arranged downstream of the cutting assembly to stack the sheets and the at least one identification sheet in such a way as to form a stack, which is identifiable by means of the at least one identification sheet, in particular for further processing.

An image reading apparatus connectable to a post-processing apparatus includes an image reading unit for transmitting image data to an inspection processing unit, and a communication unit for outputting a sheet discharge timing signal to the post-processing apparatus through a signal line. The communication unit outputs the sheet discharge timing signal having different waveforms to the post-processing apparatus on the basis of an inspection result of a sheet obtained from the inspection processing unit such that the sheet discharge timing signal includes a first waveform when the sheet determined by the inspection processing unit as that there is no image abnormality is discharged and such that the sheet discharge timing signal includes a second waveform different from the first waveform when the sheet determined by the inspection processing unit as that the image abnormality occurs is discharged.

An image forming system includes an image forming apparatus, a first conveyance path, a sheet feeding unit, a sheet post-processing unit, and a controller. The image forming apparatus has a first feed portion, and an image forming portion. The sheet feeding apparatus has a sheet stacking portion, a second feed portion, a relay conveyance portion, and a remaining amount detecting portion. When, during continuous printing, the existing number of recording sheets present in a conveyance passage from a confluence portion to the first feed portion is more than the constituting number of recording sheets contained in one bundle of sheets and in addition the sensing result of the remaining amount sensor is equal to or less than a predetermined amount, the controller controls first feed portion such that the existing number of the recording sheets is less than the constituting number of recording sheets.

An image forming apparatus that assists classification of printed sheets of documents of print jobs includes: a correspondence table showing correspondence between sticky note attributes and keywords; and a hardware processor. The attributes represent appearance features of sticky notes to be attached to edges of the sheets so as to protrude from the edges. The keywords are extracted from the documents and denote topics of the documents. In response to execution request of a new print job, the hardware processor extracts a keyword from a document of the new job, judges whether the extracted keyword partially matches any keyword in the correspondence table, and when judging positively, creates a new sticky note attribute partially having an appearance feature represented by the sticky note attribute corresponding to the partially matching keyword in the correspondence table, and adds the new sticky note attribute to the correspondence table together with the extracted keyword.
