I have a problem
with M & K on a Konica 8050
Test circles C & Y are perfect M & K scattered
Bar test the right side is perfect the left almost very light
Are you getting this when you copy or are you printing internal test patterns?
Are you a technician if your are have you check the DV units, charge coronas, transfer belt and M & K transfer rollers?
If not time to call one.

Get your facts first, and then you can distort them as much as you please.
I’m not as of yet familiar with the terminology (right side, left side) but if this is operator non-operator density, check corona wire is on the post.
