A for detecting an interchangeable worktable of a laser plotter for cutting, engraving, marking, and/or labeling a workpiece, wherein at least one radiation source in a form of a laser is used in a housing of the laser plotter, and when the at least one radiation source is activated, a laser beam is directed via deflection elements to a focusing unit, and the worktable is captured by at least one camera wherein the at least one camera captures at least one image of the worktable of the laser plotter and sends it to a table analysis software of a software on the laser plotter, whereupon one or more defined evaluation positions of the captured image of the worktable are evaluated by the table analysis software, in which features of the worktable are compared with stored features of possible worktables, or types of markings are read out.
