In this method, first a plurality of register marks, each consisting of at least one starting line, a background line and a first register line, is printed, said background line consisting of a second color which offers sufficient contrast with respect to the first color for a detection above the specified threshold value on the register sensor if the first register line is printed on the background line, and said background line having a width that is by X mm greater than the first register line, and said starting line, said background line and said first register line being printed with the use of the pre-determined control parameters, which, in the normal case, cause the first register line to be printed on the background line. Subsequently, it is detected whether the first register line has been recognized by the register sensor above the pre-determined threshold value as being completely positioned on the background line. If this is not the case, then, in accordance with the method, at least one pre-determined control parameter for printing the first register line is changed and printing of the register marks and the detection are repeated.

If the sheet does not match the frame position within predetermined limits, the start of frame signal is issued at a specified time following the generation of the frame clock signal in accordance with which the sheet was fed into the frame, wherein the specified time corresponds to the predetermined fixed time to which a time shift is added, wherein the time shift is determined on the basis of the deviation of the actual sheet. Finally, the sheet is aligned in-track in accordance with the start of frame signal, and the thus aligned sheet is transported through the print module in alignment with the latent toner image to transfer the same to the sheet. | 04-19-2012 |
