Press ◀, ▶, ▲ or ▼ to move the center of the blade over the crop marks. The center of the blade should only be over the crop marks, and does not need to be aligned with the center of the crop marks. Press ENTER. Check whether crop marks can be read. If reading succeeds, the following message appears. Proceed to the next step. If reading fails, the following message appears. It is possible that crop marks cannot be detected because they are not the crop marks output from the software RIP that is compatible with this machine. Crop marks drawn using drawing software also cannot be detected. Use the software RIP that is compatible with this machine to output the crop marks and redo the correction from the start. If detection failed even with crop marks output by the compatible software RIP, redo the correction from the sensor correction stage.
