My scanner just started smearing the first page of a duplex to pdf but when I scan just front of document it doesn't smear it
Your question is not clear.
Sometimes using technical jargon makes it harder for people to understand each other (this applies to both askers and answerers).
I always advise askers to use normal language as much as possible and answerers to do the same and where jargon is unavoidable, to explain as they go along.
Please post again to clarify what you mean by "..a duplex to pdf..", in normal language not in technical jargon.
A PDF is not a real, physical document. It is a digital document on a computer or a webpage created in PDF format.
A Duplex document is a real document, printed on both sides of each sheet of paper.
If you are trying to scan a multiple page Duplex Document using the Sheet Feeder of your scanner, the ink on the reverse side may be getting caught up in, affecting and/or staining one of the rollers in the Sheet Feeder.
The bottom roller in most non-industrial Scanner Sheet Feeders expects to touch only the plain reverse side of a sheet of paper as it is passed through and turned over to rest on the Platten (scanning surface) of the scanner ready to be scanned.
Multifunction printers with built in scanners and sheet feeders and duplex printing capability are designed in a way that makes them more forgiving of dealing with duplex printed paper.
Duplex printing printed in a laser printer is less likely to cause a problem as long as it is allowed to dry thoroughly. Inkjet printing that is allowed to drry thoroughly should also be okay.
If the scanning is being attempted very soon after printing, then the wetness of the printing may be the problem.
Sheet Feeders that handle duplex printed sheets invariably become stained and need periodic cleaning.
If the document is not too long, you may have to scan it manually, page-by-page.
If the document exists as a PDF somewhere on your computer or on the internet, then it is unclear why you would need to scan it. This is why your question is puzzling.
Post a further comment, if this answer does not help you solve the problem.
I hope this helps.
