Abstract: A method for imprinting objects, including providing a printing machine configured to deliver at least one object to be imprinted to a printing apparatus using a retaining apparatus or an inscription carrier. A data processing system is provided and includes at least one print pattern stored in at least one database. The data processing system is connected to the printing machine and configured to control the printing machine. A liquid is applied so as to generate the at least one print pattern on a surface of the at least one object using the printing apparatus. The at least one object is then exposed to a radiation so as to dry and cure the liquid and then the retaining apparatus or the inscription carrier is conveyed to an output station. The retaining apparatus and inscription carrier are stackable in the output station.

Abstract: A method for inscribing a substrate with an inkjet printer using a light-curing ink. The method includes traversing, by the carriage, to the first end position at a first travel speed. The light-curing ink is sprayed-on along an inscription row onto the substrate using the print head during the traversing to the first end position. The sprayed-on ink is irradiated, for curing, using the illumination head during the traversing to the first end position. The carriage is traversed from the first end position to the second end position along the inscription row at a second travel speed, the second travel speed being lower than the first travel speed. The print head is inactive during the traversing to the second end position. The sprayed-on ink is irradiated using the illumination head during the traversing to the second end position. The substrate is then advanced using the transport apparatus.

Abstract: An ink printer having a printer body having two side walls arranged at a longitudinal distance from one another and a user side as defined along a longitudinal side of the printer body between the two side walls, the printer body defining a reservoir within the printer body. An exchangeable tank is removably insertable into the printer body so as to supply ink to the reservoir. A printer ink connection is arranged at the printer body, an ink connection arranged at a side of the exchangeable tank, the tank side having a defined cross-section, the printer ink connection and the tank ink connection being arranged so as to be connectable to one another after insertion of the exchangeable tank into the printer body. A basin-type transverse carrier arranged longitudinally between the two side walls proximal the user side, the basin-type transverse carrier having an open top portion that accommodates the at least one exchangeable tank.

Abstract: A computer printer which has a print head and a printing bed plate comprises an apparatus to adjust the distance between the print head and the printing bed plate to thereby allow for printing on charts which are not of uniform thickness. The distance adjustment apparatus comprises a rigidly mounted sensing roller and/or a leading or trailing feeler lever, which electronically controls the print head distance.

Abstract: An arrangement for detachably securing together pairs of substantially perpendicular thin-walled, planar, generally flat structural parts (1, 2) which may define wall, top, bottom and/or side members as in the frame of data processing apparatus. A first structural part (1) is provided with calibrated slot openings (3a) for receiving contoured projections (4) on the second structural part (2). The first part (1) also includes at least a passage (8) through which a threaded screw (6) is journaled, and the second part (2) is provided with a cutout 10, opposite the screw passage (8) and aligned with the passage axis (9), configured and dimensioned for engagement with the threads of the screw (6). This arrangement enables detachable securement of the first and second structural parts (1, 2) utilizing a minimum of separate components and a minimum number of assembly steps or operations thus yielding a considerably more cost-effective attachment arrangement than heretofore known.

Abstract: A sensing device is disclosed for sensing the front edge (1a) or the rear edge (1b) of a recording material carrier (1) in a processing apparatus, wherein a feeler probe lever (2) rests on the spring-supported switching element (3a) of a microswitch (3), and wherein the connection terminal contacts (5a, 5b) of the microswitch (3) are connected to an electronic control or, respectively, display circuit (4). The invention device presents a purely mechanical, economically produceable sensing device which functions for all kinds of recording material carriers and which is wear-resistant and allows to determine with high accuracy the front edge (1a) or the rear edge (1b) of a recording material carrier (1).

Abstract: The print head (9) disposed on a print-head carriage (8) can be moved back and forth parallel to a print support (13) between end positions (8a, 8b) and can be set perpendicular to the print-surface support (13) against a spring force of, for example, a leg spring (14) relative to the print surface support (13) in the context of a device for the setting of the distance of a print head (9) on a thick print material (10) in an office machine, in particular in a printer for savings booklets or vouchers.In addition, at least one rotatable roller (15), supported at the print-head front face (9a), is provided, which roller rests on a bendable strip (16) running in parallel to the print surface support (13), where the bendable strip (16) rests solidly on the thick printing material (10) during the printing process.

The print-head carriage (3) supports a print head (4) and an ink-ribbon guide (8), disposed on the print-head carriage (3). The print head (4) can be exchanged even by the operating personnel of the matrix printer by using a print head (4) which is exchangeable in a mechanical guide (6) and which is connected with an electric plug connection (7) and is thus removable and again insertable into the print-head carriage (3). At least one tiltable ink-ribbon guide (8) is disposed on the print-head carriage (3) and serves as a locking means (9) for the inserted print head (4) on the print-head carriage (3).

Abstract: A printing mechanism is provided with a rotary cutter mounted on a printing trolley to enable a recording medium or document to be cut as the printing trolley moves during a printing operation. The recording medium is supported by a platen which has a counteracting edge cooperating with the rotary cutter and a control mechanism operates to actuate the rotary cutter between an active position for cutting and a lifted inactive position with a spring operating to apply a spring force against the rotary cutter tending to urge it against the counteracting edge.

Abstract: A printing apparatus of modular construction includes a printing mechanism with a pivotally mounted printing head, a continuous form feed part and an individual form feed part. To provide a compact construction in which the printing operation can be viewed by the operator, the individual form feed part is constructed as a base unit so that the individual form is fed into the apparatus and transported horizontally. The printing mechanism and continuous form feed part are positioned above the base unit. As a result, with the apparatus mounted on a table, printing on the printing base of the continuous form feed part takes place below the eye level of the operator. To insert the continuous form, the continuous form feed part can be pivoted away from the printing mechanism. In addition, the printing mechanism and the continuous form feed part can be pivoted relative to the base unit to gain access to the path of the individual forms on the base unit.
