Hello,

A dirty glass base can cause ‘spots’ or blemishes to appear on your final printout. Additionally, if you had some sort of opaque liquid that may have transferred on to the glass base from a previous operation. But the majority of the unwanted vertical lines are generally caused by either a dirty or damaged print roller or faulty LEDs in the Scanner Module.

To separate one from the other you have to check the following:

Do you only see the lines with a Scan operation?
Do your print jobs print fine without any unwanted lines?

If you only see the unwanted lines during a Scan operation, then most likely you have a fault/dirty/obstructed LED module.

If you see the unwanted lines with all print operations (Scan, Print and Copy), then you most likely have a worn out, damaged or dirty Print Roller.

Hope this helps…

    Hi, I found the balck line with a Scan operation when I choose the "auto" scan source" in my Dell 2335. As you mentioned, it could be a fault/dirty/obstructed LED module. How can I do for the issue? Thanks.

Colored lines on a copy page


To fix the colored lines on a copy page do the below steps

  1. Disconnect the power cord, wait five seconds, and then plug it back in. This will reinitialize the unit and force the scanner to calibrate again.
  2. Examine the scanner glass and white scan backing. Clean the scanner glass and scan backing if they are not clean. To clean the scanner glass and scan backing, use a soft cloth towel slightly dampened with clean water.
  3. With the product turned on, open the scanner cover and check the bulb assembly. If the scanner bulb is not lit, the unit must be serviced.
  4. Verify that the alignment page is placed on the scanner glass or in the automatic document feeder (if equipped) correctly. Place the printed side down.
  5. Make a copy of the alignment page. The unit will make a copy even if the alignment message is displayed. Compare the copy to the original. If vertical lines appear in the copy, check to see if the scanner assembly requires cleaning. If cleaning the scanner assembly does not correct the problem, service the product.

Brother MFC-7820N Printer--vertical lines


You need to clean the scanner glass. Also known as the strip glass. It is a 1 inch wide strip of glass that runs from the front to the back. Your documents pass over this glass when they are scanned. Some of the wax crayon probably smeared off onto the glass and now when you scan the scanner sees these marks as stationary and thus records them as solid lines. Just look into the scanner section where your documents are fed in or depending on model, some are just to the left of the large original glass.
Good Luck and thank you for using Fixya.

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

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.

Vertical line on page when scanning/faxing


Clean the scanner glass. You probably have some dirt or whiteout on it. Open up the top feeder and look at the narrow glass and you'll probably find it.

Brother Scanner, scans the page but prints black and vertical


I called technical support for this issue previously with my brother mfc. It would only do this during color scanning. b&w scanning was just fine. The tech support put me through resetting the reference point of the scanner through a series of button pressing and closing and opening the paper feeder. I kept gettting the same lousy results. Then they determined that the scanner module needs replacing and I needed to take to the nearest service center.

Vertical lines in scanned documents


Scan glass has muck on it, needs to be perfectly clear, it is just in where you feed originals.

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.
