On The Binding Edge On A4 & SRA4 We Are Getting Frequently. Magenta Mainly Rubbing Against The Sheet Now The First Thing I Thought It Could Be The Paper But We Have 4 Different Stocks And It Does It On All.
The Engineers Fix The Problem But Maybe Only For A Couple Of Days Is There Anyone That Could Give Me A Clue As To What It Could Be As I'm Having To Run The Paper SEF Due To It Rubbing Against The Sheet On LEF.
At The Moment It's With Yellow Magenta & Black.
Changed The Cleaning Blade,Transfer Dicorotron,Detack Dicorotron,Preclean Dicorotron & The Pretransfer Dicorotron And Still it is there.

Do the markings appear evenly spaced?

Hard to picture what you are describing. What do the marks look like?

On the LE of the stock, at times the TAB assembly will leave marks roughly the width of the plastic tabs. They appear as streaks or just small markings, but always approx 1/4" apart. Replacing the TAB usually takes care of the issue.
