Fiducials not found. Fiducial row not found. Use the Move Substrate buttons to position the first fiducial row on the print-zone back light line and try again. If the problem persists, call your support representative. Fiducial reading error Cannot read fiducial row properly. Check the sharpness of the white line inside the fiducial marks printed on side A. If a general defect is found, it can affect the reading. Align printheads and reprint side A. Top Row Left Fiducial measurement failed. Left-side fiducial measurement failed. Check whether the edge holder is too close to the marks, and ensure that the fiducial line is not too skewed. If so, correct it by reloading the substrate. You can also check that the platen protector is correctly positioned, not projecting any shadow that could affect the measure. Top Row Right Fiducial measurement failed.
