An image forming apparatus includes plural rotating members that are rotatable; an annular circulating member that is wound around the plural rotating members and circulates when the rotating members rotate; a retaining member attached to an attaching portion of the circulating member and that circulates together with the circulating member, the retaining member being configured to retain a recording medium in an area where the attaching portion comes into contact with one of the rotating members; an image forming section that forms an image on the recording medium at an image forming position defined on a circulation path along which the circulating member circulates; a delivering unit that delivers the recording medium to a retaining position where the recording medium is to be retained by the retaining member; a detector that detects rotation of the one rotating member; and a controller that controls delivery of the recording medium from the delivering unit to the retaining position, the delivery being controlled with reference to information detected by the detector.

A printing apparatus including a plurality of printing units along one guide can read test patterns printed with a plurality of types of conveying amount of a recording medium and determine a conveying amount based on the reading result.

A digital printing machine includes a first sheet-conveying belt made of a first material, a second sheet-conveying belt made of a second material, and a print head for printing on a front side and a back side of the print sheet. The print head is directed towards the first sheet-conveying belt. A reversing device reverses the print sheet between receiving a print on the front side and receiving a print on the back side. A drier dries a print that has been printed onto the print sheet by the print head. The drier is directed towards the second sheet-conveying belt. For instance, the first sheet-conveying belt may be a metal belt and the second sheet-conveying belt may be a plastic belt.

A sheet-fed press includes at least two units embodied as modules. At least two of the modules respectively comprise at least one individual drive which is used to transport a sheet through the respective module or through at least one active region of the respective module. At least one of the at least two modules is configured as a non-impact cover module. At least one component of the at least second module comprises at least one drying system or one drying device. The sheet-fed press includes a transport path for transporting the sheets. At least the section of the transport path provided for the sheets, and secured by the non-impact cover module, extends at least essentially flat or essentially horizontally.

There are provided a liquid jetting apparatus and a method of coping with the floating of a medium that enable the originally required moving distance of a liquid jet head to be set in a case where the contact between the liquid jet head and a medium caused by the floating of the medium is to be avoided. The liquid jetting apparatus includes a first medium floating detection unit (140) that detects the floating of a medium, a first head raising/lowering unit (400) that moves a first liquid jet head, a first movement parameter setting unit (142) that sets a first movement parameter, a first head raising/lowering control unit (120) that controls the first head raising/lowering unit, a second head raising/lowering unit (400) that moves a second liquid jet head, a second movement parameter setting unit (142) that sets a second movement parameter separately from the first movement parameter, and a second head raising/lowering control unit (120) that controls the second head raising/lowering unit.

A printing system is described that has an intermediate transfer member in the form of a seamed endless belt for transporting an ink image from an image forming station, at which an ink image is deposited on the intermediate transfer member, to an impression station, where the ink image is transferred onto a printing substrate. The belt has along its edges formations of a greater thickness than the belt. The formations are received in channels to guide the belt and maintain the belt under lateral tension. Two drive members are provided, each located within a respective one of the channels. The two drive members are connected for movement in synchronism with one another and each has a respective laterally projecting gripper shaped for form locking engagement with the formations on a leading end of a strip from which the intermediate transfer member is to be formed. Rotation of the drive members during installation of a new intermediate transfer member serves to thread the strip through the printing system by pulling the strip from its leading end.

An aqueous ink printer includes a dryer that enables coated substrates to be printed with aqueous ink images. The dryer is configured to receive substrates from a first substrate transport and to hold a plurality of the substrates for a predetermined period of time to dry the aqueous ink images on the substrates before independently releasing each substrate in the plurality of substrates to a second substrate transport.
