When we send a document to the printer from a computer it works great. But if we take that same piece of paper and run it through the top feeder or place it on the glass then the result is an offset document. It seems to shift the document over and up about 1/4". Did something get moved on the inside?

Check your flat bed and Document feeder scanning glass need to be clean, if any dot or dust in scanning glass of document feeder it will appear a line, check this points first 1- Check printouts from computer or FAX if it is clean problem in scanning section 2- Check using Copying a blank paper using only Flatbed if it prints without any line its problem from document feeder Scanning glass So solution is clean the Document feeder scanning glass using wet cloth, note careful about wet cloth switch off the machine and clean it
If it is just puting lines on the copies ONLY when using the feeder here is all you need to do to clean that thoroughly.
Get a phillips screw driver. Lift the document feeder, you will see the "seal glass" about 1 inch wide on the left side. Remove the 2 silver screws, One on each end. Lift that glass up and out. Lay it on a white piece of paper. Take some alcohol and a regular piece of copy paper and clean that until you see nothing on that glass by placing it against the white paper. Get every little speck off. Then put the glass back in.
If you want to clean the entire scanner that is a different procedure all together. Let me know .
You need to lift the document feeder and clean the small **** exposure glass located to the left of the main exposure glass.Any foreign substance on this glass(ink, glue, correction fluid,etc.)will cause lines on copies when you use the feeder.
You load the originals print side uo on the document feeder tray or print side down on the glass.
To send a single page fax you can either load the original on document feeder tray or on the glass; to send a multi-page fax you must use the document feeder tray.
Document feeder Paper feed rollers should be cleaned with alcohol, blow out the document feed area with compressed air (computer duster), check feeder for bits of paper, post it notes, and signature flags. Clean glass, check for sticky areas on the glass.
As the page you wish to copy goes through the document feeder, it passes the scanner as well as a white plastic band that the scanner "compares" the dark writing or data on the page to. If this white plastic band is not very clean, the scanner reads the dirt as if it is part of the image you are scanning. Try cleaning the band as thoroughly as possible, as well as the small piece of glass to the left of the larger glass on the flat bed scanner. Make another copy to test your results.
look to the side of your big glass and you'll see a piece of glass about 1.5" wide. thats the galss that is used for scanning from the feeder. theres got to be something on that glass. possibly white-out or even a small speck of toner can cause that. look closely.
If you lift the document feeder, you will see a narrow piece of glass
on the left side. Originals are scanned across this when the feeder is
used, so a small speck of dirt becomes a line when copying. clean the
glass, and it should be good to go.
The problem is that that there a small piece of glass that the doc feeder use's to scan the orginal. You will have to clean the small glass it's about a half of a inch piece and is normally under the doc feeder unit. It will either be to the right side of the main copy board glass or it is under the doc feed unit where the paper goes down through the feeder. It is mostly some white out on the glass, just clean with a dam cloth with water or windex..... Good Luck
