Vertical lines when copying from feeder or glass - does not happen when printing from computer or scanning documents.


Inspect the glass below the feeder for ink or ink correction liquid remnants from previous scanned documents. Clean them out.

Black vertical lines come and go for scans to computer and copies


I suspect the Document Feeder is not aligned properly and light is leaking in. You will need to have a technician in to check the alignment of the scanner to see if it needs to be readjusted. random black lines on edges usually indicate light leaking into the scan area.

Probably there is nothing wrong with that scanner, just open and clean document feder with alcohol or glass cleaner.

Xerox WorkCentre 4150, 3 vertical white lines in all feeder scans


the problem is in the scanner, open it up and see if you can find any smudges, and clean any obstruction, any ink, liquid eraser residuals, can cause this part to appear as lines on your copied faxed image.
dont concentrate on the printer this is a scanner problem

Vertical lines about one half inch apart down center of the page when fed through the document feeder. No problem with fladbed copying or scanning.


If you open to document feeder and look at the glass when scanning via flatbed, just to the left will be a smaller piece of glass. That is the glass used when scanning through the feeder. Clean that glass as there is probably a couple of spots on it.

Vertical black line in scan document not in copies through document feeder


Lift the lid and to the left of the main glass is a smaller glass; that is what scans during the feeding process. Make sure that it is completely clean; even a speck of dust can cause a line to appear. I took a lens wipe and cleaned mine and my line was gone.

Print Problem - vertical lines


If the problem only occurs when using the document feeder, the problem is not usually caused by the drum. When using the document feeder, try to notice where the scanner (the light assembly under your scan glass)stops just before the paper is being fed. Some multifunction machines have a small piece of glass that is separate from the large scan glass and the scanner assembly stays parked underneith it as the original is being fed over it. Most likely there is something on the glass where the scanner parks as originals are being fed thru the feeder. When putting your original on the large scan glass to copy, the mark on the glass will only show as a spot, but will show as a vertical line thru the whole copy when using the feeder.

Scanner inserts vertical line on some documents


Clean the glass with IsoPropyl Alcohol. Dont use any other solvent. A speck of dust stuck to the glass can give a continuous line in the output
