The present invention relates to a device for treating substrates which device is modular and versatile in use. The device for treating substrates comprises a feeder and one or more first sub-structure modules which each comprise a pressure cylinder with devices for fixing a lift and a sheet-conveying device and one or more second sub-structure modules which respectively have a transport cylinder with openings formed on the cover surface thereof, and having devices for fixing a lift and a sheet conveying device. All of the first or second sub-structure modules have the same intersection point for connecting the sub-structure modules on one of the inlet and the exit side and they all can be equipped with an attachment module.

A post-processing apparatus includes a transport path having a first path member and a second path member, a punching member disposed on the transport path to perform punching on the medium. The transport path includes a first transport path disposed downstream of the punching member in a transport direction and a second transport path continuously extending downstream of the first transport path in the transport path, the second transport path having a curved shape to hold the medium in a curved state, the first path member in the second transport path forms an outer side of the curved shape and is disposed at a position further separated from the first surface than the first path member in the first transport path, and an upstream end in the transport direction of the medium in the curved state is moved from the first transport path to the second transport path.

A device for processing substrates uses a separation system. Processed substrates can be separated into one or more waste parts and at least one blank. Improved flexibility for treating substrates is provided. The separation system comprises a transport cylinder and a stripping cylinder associated therewith. The transport cylinder has first openings and has a detachably secured packing having depressions in which perforations are formed, with at least one perforation covering at least one first opening. The stripping cylinder has a detachably secured packing having raised areas that correspond to the depressions.

A sheet processing apparatus includes a blade having a plurality of teeth aligned in a row, a mover to move in a direction in which the plurality of teeth is aligned and form a perforation in a sheet sandwiched by the blade and the mover, and a pressure device to press the mover toward the blade.

A printing system is disclosed. The printing system includes a printing unit, a sheet processing unit, and a control unit. The sheet processing unit performs a designated sheet process for the printed sheet using a die that is manually selected by a user and attached to the sheet processing unit. When the die for performing the designated sheet process is not attached to the sheet processing unit, it is determined, before the printing unit starts printing the image on a first sheet on which the printing unit prints the image firstly among sheets on which the designated sheet process is to be performed, not to perform the designated sheet process for the sheets on which the designated sheet process is to be performed. The printing unit starts printing the image on the sheets on which the designated sheet process is to be performed after the determination.

A device for treating substrates has a separation system, with which processed substrates can be separated into one or more waste parts and at least one blank. The device for treating substrates offers improved flexibility. The separation system comprises a transport cylinder and a stripping cylinder associated therewith. The transport cylinder is able to secure replaceable packing, along with first and second openings which, when the packing is secured, are covered at least partially by perforations that may be formed in the packing. A first air supply supplies air to the first openings and a second air supply supplies air to the second openings independently of the supply of the air to the first openings. The first and the second air supply are switchable between a suction air supply and a blower air supply.

A printing system is disclosed. The printing system includes a printing unit, a sheet processing unit, and a control unit. The sheet processing unit performs a designated sheet process for the printed sheet using a die that is manually selected by a user and attached to the sheet processing unit. When the die for performing the designated sheet process is not attached to the sheet processing unit, it is determined, before the printing unit starts printing the image on a first sheet on which the printing unit prints the image firstly among sheets on which the designated sheet process is to be performed, not to perform the designated sheet process for the sheets on which the designated sheet process is to be performed. The printing unit starts printing the image on the sheets on which the designated sheet process is to be performed after the determination.

Provided is a sheet processing apparatus having a configuration that a processing mechanism to perform a process on a sheet, a first conveying path to guide a sheet to the processing mechanism, and a second conveying path to guide a sheet are configured to be integrally removable from another component.

A method of self-adaption adjustment for post-printing treatment including steps of S1: printing a plurality of identifiers on a paper sheet for positioning actual locations of treatment on the paper sheet; S2: detecting the identifiers on the paper sheet, and locating the actual locations to be treated according to the locations of the identifiers and/or relative locations among the identifiers; and S3: adjusting locations of treatment from a post-printing treatment mechanism to the paper sheet according to the actual locations output in step S2. A system of self-adaption adjustment for post-printing treatment including a printing module, a detection module, a treatment module, a driving module and a post-printing treatment mechanism. The method and system realize the self-adaption adjustment, which effectively solves the problems that an actual value after skewing or stretching or shrinking the actual printing content is inconsistent with a theoretical value of typesetting, thus effectively improving the production efficiency and production quality, which has favorable economic and social benefits. The method and system can be widely applied in various post-printing treatment systems.

An image forming apparatus including: a printer; a puncher configured to punch the sheet printed by the printer; a binder configured to perform a bookbinding process to form a bound product in which a binding member penetrates punch holes of sheets; a first detector configured to detect a first jam of a sheet in the binder; a second detector configured to detect a second jam of a sheet which occurs upstream of the binder; an annunciator configured to notify information; and a controller configured to cause the annunciator to notify first instruction information for instructing removal of a sheet and the binding member, when the first detector has detected the first jam; and cause the annunciator to notify second instruction information for instructing removal of the second jam when the second detector has detected the second jam and the first detector has not detected the first jam.
