Hi Sally,

Open the flatbed lid and look on the left side, I believe there is the flatbed glass and another piece of glass to the left, the small strip of glass is the one used for the automatic document feeder. this piece af glass needs to be clean or you will get a line from top to bottom from any type of speck on the glass. hope this helps... if so please mark as FIXYA!!

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

When I use the feeder either for scanning or copying, the page has a black vertical line . When I make normal copies or print outs it is fine, only the feeder makes the black line. Thank you


Under the Automatic Document Feeder is a small glass.
This glass becomes dirty, creating lines on the page.
open up the scanner cover and clean the glass

Two lines, one on each side of copies made from feeder and faxes


Try cleaning the rollers inside the scanner including the glass inside and out with a soft damped cloth. Look also for a piece of paper, staple wires, paper clips or pencil lead jammed inside the rollers or somewhere in the corner.
Also, look for a foreign object or substance on the cold cathode tube light and clean it. Try also cleaning the mirror.

Black vertical lines on faxes sent using auto document feeder


If you lift up the lid on your scanning device you will notice a glass strip about 1 inch thick and then the large area of glass used for flatbed scanning. The 1 inch strip is used for ADF scanning. Because your papper is moving across the glass strip, any dot, smudge or scratch will affect your scanning and cause verticial lines down the page. Sometimes the dot is not visible to the eye. Get some glass cleaner that has alcohol in it and thoroughly clean the glass strip and it should solve your problem. If it turns out to be a scratch on the glass then cleaning won't help.

Dell All in One Printer 962-dark vertical line on photo copies


If you are running your copies through the document feeder then see if the line goes away if you make a copy directly from the glass. If the line goes away then open up the doc feeder assy. by hinging it to the left. Underneath you will find that there is a thin strip of glass that the document passes over when it is scanned. Clean this strip of glass and this should correct your problem. If there is a smudge of dirt or small line, it will come out as a solid verticle line when scanned.

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.
