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

Yes - surprisingly - we had the same problem, the gray stripe along the side of the page only showed up when the original was fed through the document feeder on top. Cleaned the small area of glass under the feeder repeatedly with no change to the resulting stripe, but then while cleaning the upper roller, above the area of glass where the scan lamp illuminates during the copying from the ADF, we found a small piece of paper adhering to the top roller in the paper path, cleaned it off, and no more band. We didn't see the bit of paper on the upper roller until we rolled it while cleaning. Still can't figure how that made a stripe....but hope this helps you.

You need to clean the glass. Open up the feeder and you have a large piece of glass for scanning and to the left a smaller piece of glass that it uses to scan from the feeder. Clean this smaller piece of glass; even the slightest smudge can leave a black streak.

There is something on your scanner glass. Clean the glass with glass cleaner. If this happens when using the automatic document feeder, open the top side cover where the paper feeds into. There is a narrow glass strip there. Clean that as well.

If this fails, the scanner head has a bad sector on the CCD and will need to be replaced. You will probably find that it will be cheaper to replace the printer entirely if that is the case.

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.

the document feeder of that unit have its own scanner glass. try opening the document feeder and clean the scanner glass with a lint free cloth that is moist with water and also clean the rollers of the document feeder

Hi,

Over time the automatic document feeder (ADF) will get dirty, occasionally causing vertical black streaks or lines in scans and copies .

Manual cleaning of the ADF might be necessary. Follow the procedure below to manually clean the ADF .

You will need the following materials:

• Soft lint-free cloths
• Glass cleaner

if you look carefully on the left side of ADF ( top feeder ) there is an assembly which u can lift , there wud be a set of rollers if u lift that part there would be a glass strip . u are suppose to clean that strip .
While holding up the inside of the ADF, clean the glass in the location of the vertical streak with one of the cotton swabs. Try cleaning the glass first with a dry cotton swab. If that does not correct the problem, then moisten the swab with glass cleaner .
If the vertical lines or streaks still appear, go through the above cleaning process again, this time cleaning the entire surface of the ADF scanner glass.
and after this try the following steps as well .
CAUTION: Use only glass cleaner. Avoid abrasives, acetone, benzene, and carbon tetrachloride, all of which can damage the scanner glass.

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.
