    摘要: A thermofixiug device for fixing toner images on a strip-shaped or sheet-like recording substrate (17) of an electrophotographic printing or copying machine contains a thermoprinting fixing station (11, 12) and a heated preheating saddle (15) located upstream of the thermoprinting fixing station in the recording substrate running direction. The preheating saddle (15) is designed as a low temperature saddle with the largest possible constructional length, so that the temperature difference between recording substrate (17) end saddle surface (24) is as small as possible. The preheating saddle has, in the recording substrate running direction, a plurality of heating zones (21, 23). A control device controls the heating zones (21, 23) in such a manner that, along the preheating saddle (15), an approximately constent thermal energy flow occurs on the saddle surface (24) to the recording substrate (17). For matching the preheating saddle (15) to various recording substrate widths, the preheating saddle is subdivided, transversely to the recording substrate heating direction, into individually drivable transverse heating zones (30/1 to 30/3).

    摘要: A printer for printing endless paper webs on both sides has two printing stations with a web turnover station therebetween. The paper web is fed in parallel side-by-side to the two printing stations which are on the same rollers. The drive of the web through the printer is by a positive drive, using pins to engage holes in the paper web, for example, into the first printing station. The drive of the paper web thereafter is by friction drive to permit slippage in the drive to compensate for variations in paper length during heating, etc. The slippage is controlled by brakes or other drag inducing devices acting on one or both of the two portions of the paper web.

    摘要: An electrographic printing or copying machine contains, by way of example, a preheating saddle (20,21) positioned upstream of a pair of fixing rollers in the recording substrate running direction and a braking element (10). The preheating saddle (20,21) and braking elements (10) form a gliding surface (23). Suction openings (18,19) in fluid communication with a vacuum-generating device ensure good contact between gliding surface (23) and recording substrate. With the aid of a valve (1), the vacuum can be matched to the operating parameters of the printing and copying machine, or to the parameters of the recording substrate.

    摘要: A printing or copying apparatus is provided having a thermofixing device for fixing a toner image to a sheet recording medium or substrate, such as paper. The apparatus has at least one cooling device operable to cool the substrate after it passes through the thermofixing device and before the substrate is stacked. The cooling performed by the cooling device prevents the toner image from undesirably sticking to an adjacently overlying substrate surface after stacking.

    摘要: The device for transporting recording media (100), used especially in a fuser station of a printer or photocopier, comprises a counter-roll (201) and a feed roll (205), mounted movably relative to the counter-roll (201), between which rolls the recording medium (100) is transported by friction. Furthermore, a guide bar (214) is arranged in the manner of a balance beam with spacing parallel to the feed roll (205) and so as to be pivotable about an axis of rotation (216) relative to the feed roll (205). In order to press the feed roll (205) against the counter-roll in a force-compensating manner, as required, spring elements (218) are arranged on the guide bar (214) on both sides of the axis of rotation and are coupled to bearing elements (206) of the feed roll (205). The guide bar can be deflected via an adjusting motor (224) for controlling the position of the recording medium (100) between the rolls (201, 205).

    摘要: A printer for selectively printing on one or both sides of a web-shaped recording medium includes a paper turn-over apparatus in the paper conveying channel. The turn-over apparatus is a removable unit and can be changed from a turn-over operation for two sided printing to a parallel conveyance for one sided printing of two recording mediums. A conveyor that moves the recording medium through the printer has an adjustable width to adapt to different recording medium widths. The conveyor includes a return which returns the recording medium to the turn-over apparatus after being printed on one side. The return includes a traction roller pair and a lever to swivel one of the rollers in and out. A connecting channel leads from the traction rollers and includes guide baffles. Conveyor rollers are arranged along the connecting channel at less than the spacing of the folds in the folded recording medium. The guide surfaces for the recording medium have air openings to generate an air pillow between the recording medium and the guide surface.

    摘要: An electrographic printer has an intermediate medium for simultaneously printing a first web section of an endless medium and a second web section arranged next to and at a distance from the first web section. Both web sections are drawn along a path past the intermediate medium by a transport system. During the printing process, a tensioning device biases the first and second web sections against the intermediate medium. A web-tensioning unit located downstream relative to the direction of transport of the transport device, applies a traction force to the web sections in the direction of travel. In addition, a first compensation device and a second compensation device separated from the first compensation device are provided between the transport device and tensioning device. The compensation devices bias the first or second web sections as appropriate, against the direction of transport during the printing process.

    摘要: An electrophotographic printer has an electro- thermally operating fixing station (23) with a heated fixing roller (86) and a feed roller (87) which can be pivoted between at least one position against the fixing roller and another position away from the fixing roller. With the aid of an unheated, pivoting paper guide saddle (93), the reel paper is guided around the fixing roller (86) at a predeterminable wrapping angle (U) for the purpose of preheating before the actual fixing. In order to fix the printed image on the reel paper (12) in an offset-free and smudge-free manner during the starting and stopping process, the movements of the elements of the fixing station (23) and the transport of the paper are coordinated in such a way that there is no relative movement between the fixing roller (86) and toner image on the reel paper (12) when the reel paper is placed against the fixing roller (86) and when the reel paper (12) is stripped off the fixing roller (86). The printer also has a pivoting print transfer station and a paper dividing device separately pivotable from the print transfer station.
