How the other halftones look like?

White voids be Dev unit or laser dirty.

If belt is worn and has some embossed lines from blade it can do similar lines. You should be able to match them with the rest of colours.

Dear Thread
try to change drum magenta with cyan! if the problem appear on cyan you should try to clean the charger if you can't do that replace the drum unit.

If the white line is opposite to feed direction then you can eliminate dirt on laser glass or even foggy edges of polygonal mirror.

to update you guys the void lines is happening in all color but only more visible on magenta color. i see some toner remain in transfer belt. i will try to clean it or replace the cleaning blade and inform you guys if this will solve the problem.
