MFC-7460DN Smudges of Ink Appear When Printing

Hello, MFC-7460DN. Smudges of ink (about 2cm in diameter) appear when printing, in regular intervals vertically along the page, about 6 per page. Replaced toner, replaced drum, opened front and back covers and cleaned everything in site. No change. Any ideas? Thank you! <!-- also-read --> <h3><b>Also Read:</b></h3> <ul> <li><a href="/diagnosing-dead-dcp-l2520dw">Diagnosing Dead DCP-L2520DW</a></li> <li><a href="/how-to-wind-a-bobbin-in-brother-printer">How to Wind a Bobbin in Brother Printer?</a></li> <li><a href="/how-to-fix-brother-scanner-not-working-issue">How to Fix Brother Scanner not Working Issue?</a></li> </ul> <!-- /also-read -->
