Abstract (en)
[origin: EP3528056A1] To achieve highly productive duplex printing in a compact printer, the present invention provides a method of correcting registration errors of media sheets that are fed to a print station via a first liftable pinch and a steering mechanism. The first liftable pinch is arranged in a sheet supply path. For each sheet fed to the print station via the supply path, there is performed a step of checking the sheet for registration errors and, if a registration error is detected, lifting the first liftable pinch and operating the steering mechanism so as to rotate the sheet. A fraction of the sheets is returned via a duplex loop and fed again to the print station, again with registration error correction.The sheets that are returned via the duplex loop are fed to the print station via a second liftable pinch without passing through the first liftable pinch again, and the liftable pinches are operated independently of one another.
