Since the same sensor is used for both paper end and black-mark detection, the printer must
know the length of the black-mark to avoid signaling end-of-paper when it detects a black-
mark. The default setting accepts black-marks in the range 3 –16 mm, and works perfectly
with the recommended black-mark length of 5 mm. Marks shorter than 3 mm are interpreted
as dirt, and marks longer than 16 mm as out-of-paper. Change both these values by changing
the printer default settings.
Black mark mode is selected by setting parameter 35 to 1, and storing the parameters.
Important • It is essential that you store the parameters in the printer for black mark
synchronization even if you enable black marks in the Windows driver. This is because
Windows is not used at paper loading, and feeding with the Feed button on the printer.
