If the reflectivity of the black marks is higher than the specified
value, the black marks may not be recognizable. Infrared light is
used for black mark detection, and the infrared reflectivity needs
to be the specified value or lower.
Check the specifications of black mark printing, and use black
marks that comply with the printer specifications.
The black marks may become recognizable by adjusting the black
mark detector.
On the operation panel, select [Menu] - [Maintenance] - [Calibra-
