SOURCE: black line down right margin

Have you tried a new toner and drum unit? if not please do so. If that doesn't work then it is a scanner lamp failure and will need replacing.

You can fix it but trying to obtain this part for such an old machine will be hard. Don't know the part number sorry.

Thanks J

SOURCE: Black line

Black lines are caused by the scanner failing. Grey or light areas are either the ****-glass under the drum unit or the drum unit itself. If you use aftermarket toner, that could be your problem. Brother is really touchy when it comes to supplies.

SOURCE: Lines of copies utilizing automatic feeder

look to the side of your big glass and you'll see a piece of glass about 1.5" wide. thats the galss that is used for scanning from the feeder. theres got to be something on that glass. possibly white-out or even a small speck of toner can cause that. look closely.

Officejet 9600: vertical lines (4) in center of page when copying using ADF. No lines when copying from glass. I tried the cleaning procedures on your trouble shooting pages. They did not help. How ca


John:
When using the ADF, the scanner doesn't move. The long rectangular platen glass on the left side of the machine is used, not the large glass. I believe that if you clean the long, thin piece of glass on the left side of the platen, your lines will disappear.

My officejet pro 8500A prints black vertical lines down the page when I make a copy. I have cleaned and aligned the printheads. What else can I do?


Happened with me too. Turned out to be a small sticky smudge on the ADF glass. That is the smaller glass scan area to the left of the large glass scanning area.
When using the ADF to scan or copy, make sure the smaller glass area is clean along with the rollers.

When scanning or copying on my C4180 a thick black line appears on the right hand side of the page. This does not happen when printing.


clean the scanner glass... completely .. if you are scanning /copying from ADF .. then clean the adf rollers as well ..

You will be able to lift the ADF rollers and there will be a mat as well underneath the rollers.. clean them as well ..
the issue would be resolved.

Savin 2545 document feeder gives a gray band on the copies


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.

When i scan or copy there is a 3/4 inch black stripe down the right side of the paper about a half inch from the side


If you are getting this result with the automatic document feeder then you should check the glass for any kind of debris that may be in way. The ADF glass should be a small strip to the left of the large plate glass. If not, or if the ADF glass is clear it is possible that particular section of the scanner has given up the ghost. Probably not worth repairing. Best off to buy a new machine. I would recommend staying away from Lexmark next time, they kill you on ink anyway.

Stripe on copy


When you copy through the ADF, the machine scans over what is called the '**** glass'. If you lift the ADF you will see a thin strip of glass that runs front to rear, just to the side of the original glass.
You must clean the glass--- probably white-out, ink, etc... also look to see if a piece of paper, staple, etc.... is laying over the glass. When something is on the glass, the machine scans it down the page.

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.

Black streaks across the page


hello,first of all,make a copy true the adf,and the next on the platen glass,if both copys are good,then the problem is inside the machine,i.e.drum unit or fuser roller damage.
if the strikes only occurs,by using the adf,then cleaning the scanner platen glass,it is the small glass unit!!! on the left side,from the big platen glass..

good luck Sjeuf
