Either faulty Bk IU or dirty laser view window. Maybe both if modifications have not been done!

Try this: BTW all the below is in the USER MANUAL or Administrator Manual freely available on konicaminolta.com site


Open Tray 1 or 2 and take out the cleaning tool
Open front cover, take out waste box, clean the laser window for Bk Imaging unit (may as well do the other colors CMY).
Put Waste box back in to machine, close front door.
Put Cleaning tool back to tray 1 or 2.

Go to Admin Mode:

System > Expert > Image Stabilization > Stabilization Only> Start
Gradation adjust> print > put the print on glass > start >

Come out of admin mode>

Make a print.

If it isn't working for you you may need a Bk IU or a technician to check out for all the modification that are necessary to avoid developer dropping on to the laser window.
