Scratched glass on the scanner

My ADF feeder has a slight scratch on the glass which is resulting in black streaks on photocopies. Is this repairable or will I need to replace the machine? Much thanks in advance.

You could take it out and take it to a glass shop and have a piece cut - will probably be costly. I doubt it could be fixed

Black streak on scanned printed copies


Hi

Open your scanner lid and make sure their is no dirty marks sitting on your scanner glass. Also does this happen on the scanner glass or when using the ADF? If its on the ADF its most likely that the glass is dirty and needs to be cleaned. 6c66c542-b5d2-4d0a-8a21-00c054973a29.png

Black lines when sending faxes or making copies


I've been getting many calls asking me why their fax/copiers/printers are getting black lines when they send faxes and making copies while using the automatic document feeder, and not when they open the document feeder and use the glass.

What happens, when you fax or copy papers that has white-out or some material that can flake off, it gets embedded on the ADF glass and the unit thinks its part of the paper.

99% of the time, what needs to be done is to clean the small glass, usually using fingernails to scratch off the dirt, or using a lint free cloth slightly moistened, should do the trick. Just go over it several times until it comes off.

If the lines are thick, it usually indicates a damaged scanner assembly, in cases with the Brother machines, not expensive to fix. With other units, its a different story, either because they do not sell the scanner assembly as a part, or units are sent in for whole unit repairs.

Copies run through the feeder have black line on them, copies on glass & faxes are okay


Clean the ADF scanner glass. This is the small strip of glass that is just to the left of the large glass. Normally there is a label on the machine right by this glass that instructs you to clean this strip of glass whenever streaks appear when using the ADF or Automatic Document Feeder. Sometimes toner/dirt gets stuck on this strip of glass so clean it well using a soft cloth with some glass cleaner.
Good Luck and Thank You for using Fixya

When I make a photocopy I get a dark vertical line down the page. In fact, now I get two dark lines. It has something to do with the scanner, because it happens when I send someone a fax as well. ...


Do you use the automatic document feeder (ADF) when you photocopy and fax? Do you use the platen (lift the cover up) when you scan a document? If so, you probably have some dirt or foreign material in the ADF scanner area, which is a thin glass area to the left of the glass platen. Clean this area with a damp cloth and dry it before trying again. There is a plastic strip covering this area, and if this is scratched it can be removed and replaced.

Your glass is dirty. The reason you don't get it from the ADF is because it uses a smaller different glass ahead of the glass that you use when you put it on the scanner. Clean the glass using a lint free cloth and some glass cleaner or, better yet, lens cleaner.

Panasonic UF-490 - Two streaks down page


Either the glass is scratched or the sensor has gone bad that is used to scan the image.  Are you using a document feeder or laying it flat on the glass?  If you are laying it flat on the glass then it is most likely a sensor going bad.  If you are feeding it through the document feeder it could be that the feeder itself needs to be cleaned, or the paper path through the feeder.
If it is the sensor you will need to send it out for repair.  There may be an option to re-calibrate the scanner in the software, that may help if the sensor has just degraded and not failed.
I hope that helps.

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.

Line in copies that go thru 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.
