C250 K image units getting black line LE to TE.

K Image units not going to life, getting toner on edge of copies.
Suspect waste toner auger in image unit.
Can anything be done to get more life from K image units.

I see this one alot I think its because of the charge getting dirty at edge of the image causing it to leak and pull up toner onto the drum. I'd love to know how to fix it aswell though because I see this almost all the time normally what I do is adjust the actual tray a couple of mm so its off the copy edge but really I'd rather be able to fix it.

Thanks for the reply, I have been sending them back to Konica for credit.

This is due to Charge Grid, which gets contaminated at both ends, especially at back side as waste toner outlet is at backside.
