Sharp MX3571 voids on black print only

[Oso]

Hey y'all I've replaced the K drum, the ITB, fuser and have tried a different developer unit and i'm still getting voids across the pages at the top and about midway down the page. The void is even ands across from left to right. Color samples print just fine. This only happens with the black print. Anyone have any ideas where else to look?

Did you clean the LSU slit glass? If it was the DV, you would think that you would see it on the brush.

I've seen issues with the process unit cover, the one you remove to replace the blade behind the chare unit. The tab that clicks it in to place can break and cause similar issues. Also, clean the discharge lamp/charge unit.

Thank you for your answer. That was, in fact the solution to my issue. Cheers!
