Even if Auto 2 is selected, the black areas or text will be printed using three colours ( CMY, composite black ).
Cause:This might occur when using KPDL Classic Driver or KX Driver in KPDL Emulation.
Solution:Use PCL Classic Driver or change emulation in KX Driver to PCL. Alternatively, the passthrough mode can be deactivated in KX Driver with KPDL Emulation, to solve this problem.
