A method for a printer 1 comprising a transport device comprising an endless transport belt 4 for a stepwise transport of a print medium in a transport direction x from an input roller 2A to a print station 7 and supported on a pair of support rollers 3A, 3B, 3C, which between them define a medium support plane, over which medium support plane the print station 7 is provided, wherein the method comprises the step of repeatedly applying a feedforward to the input roller to get a correct media step.

A multi-lane printer for printing rigids and a method therefor. The print controller of the multi-lane printer comprises a first print queue comprises a first group of print jobs to be printed on print media which is intended to be left aligned in a lane, a second print queue comprises a second group of print jobs to be printed on print media which is intended to be right aligned in a lane, and a single print queue comprising both the first and the second group of print jobs. The single print queue is shown on the user interface in a single queue view. The first and second queue together are shown in a dual queue view on the use interface screen. The method provides rules for ordering the print jobs when switching between the single queue view and the dual queue view.

A method for a printer comprising a transport device comprising an endless transport belt supported on a pair of support rollers, which between them define a medium support plane, over which medium support plane a print station is provided. The method comprises the steps of determining a plurality of different positions in the plurality of parallel lanes for the individual print media, the plurality of positions spread in a direction perpendicular to a scanning direction of the print station, transporting in parallel but not necessarily simultaneously a plurality of individual print media perpendicular to a scanning direction of the print station in a plurality of parallel lanes towards the medium support plane, and based on the determined plurality of different positions, independently activating a signalling object in each lane when a leading edge of a fed individual print medium reaches each of the different positions in the lane. Each determined position in a lane has a different distance to a start position for a start of an automatic transport of the print medium to the medium support plane for ejecting marking material on the print medium by the print station, and each determined position in the lane corresponds to a different signal given by the signalling object in the lane when activated.

A method for calibration of a printer for a transparent medium. The printer comprises a feed table for feeding media to a print surface comprising a vacuum system to suck media to the print surface, an area camera above the feed table for detecting fed media, and a print controller for controlling of printing on print media. The method comprises the step of placing a sheet with an indicator line on top of the feed table at the position of a trailing edge of the transparent medium.

A printer for printing on print media to be fed in at least one lane of a feed table set up in front of a roller conveyor belt for feeding the print media in a transport direction (x) on the roller conveyor belt to a print surface comprising a vacuum system to suck media to the print surface. The at least one lane is provided with a signalling element at a first position which corresponds to a position of a trailing edge of a print medium fed in the lane at a start moment of a transport of the print medium from the feed table to the print surface by means of the roller conveyor belt.

A method of conveying a sheet (16) in a sheet processing apparatus comprising a perforated sheet transport belt (10) and a vacuum source (14) disposed underneath the belt (10) so as to attract the sheet (16) to the belt, wherein a suction pressure is varied dependent upon the position of the sheet (16), characterized by a step of creating a suction pressure wave that propagates along the belt (10) and accompanies the leading edge of the sheet (16).

A user interface for a printer, the user interface having a screen and being arranged to display a plurality of display items on the screen simultaneously in a configurable layout. The layout specifies at least one of a selection of display items to be displayed simultaneously and a configuration of frames to be displayed that are related to the display items,. Each display item is related to a data object for a printing device. Each data object has a fluent level relative to a window of opportunity for an efficient use of the printing device. A size of a frame dynamically corresponds to the fluent level relative to the window of opportunity of a data object related to a selected display item.

A printer for outputting output stacks of printed print media. The printer comprises a print controller for controlling the printing process and a plurality of modules through which a paper path is defined along which sheets are transported from a first module of the plurality to a last module of the plurality. The printer comprises a user display which is bi-directionally movable by a driving device along a track system extending on top of and over at least two of the plurality of modules. Upon a receipt of an error signal by the print controller from a module out of the at least two modules, the user display is automatically moved to the module along the track system.

A hot steam generator (100) comprising: a thermally conductive and heatable body (1) having at least one internal channel (3), each with a channel inlet (2) and a channel outlet (6), into which a catching means (4) for catching carried-away water droplets is embedded; a water supply to the channel inlet adjustable to a feed volume rate; a heating device adapted to heat the body to a temperature greater than or equal to 100°C.

A printer comprising a plurality of displays for parallel user interaction, a print controller for controlling the printer, wherein the print controller comprises a session system which registers a session from a user via a display of the plurality of displays, wherein the session system keeps track of which session is requested per user per display and an authorization system which keeps track of rights given to the user of a display for a kind of action to be performed during a session.
