Thick Black Line on my copies and faxes

When I make copies or send faxes a 1/2 x 11" perfectly even line appears down the middle of the page.  When I print pages from my computer, everything is fine.  I have cleaned the scan glass and white piece strip inside of the printer, but that has not helped.

Can't image it being anything but scan glass, if prints are fine, are you sure you cleaning scan glass(inside of where originals are fed)?

If so then scanner lamp faulty, but I've never come across it myself on this model.

I have a Epson cx11 and get a black vertical line down the middle of scans and copies


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

4215 all in one office yet. When making a copy


Sounds like you're having a problem with the automatic document feeder. The scanner is continuing to scan but the paper is not advancing as it should during the first part of the infeed. Check to see if something is inside retarding the path of the scanned document. Or it could be worn rollers in the ADF.

My brother MFC 8500 is receiving alright but everything I send out has a big black streak going down the right side of the page. Confirmation page also has big black streak.


Let me see if I got this right.

The received fax is clean but when you send one out it has a black streak on it.
Cool! So far so good.
Makes sense because for sending, the fax scans the original document and parts of the scanning area could be dirty and so on. Therefore a black streak may appear.
The same black streak would also appear when you make a copy, because the original document must also be scanned.
Logical!

However for receiving faxes, the machine uses the internal memory and the print engine only, and the same applies to printing the transaction report, which comes from inside via the print engine.
The scanner has no rol in either situation.

Now I'm lost!

Unwanted verticle line on fax copies


Most likely a fax has been sent or a page copied with 'white out' (Liquid Paper), still wet on the page. As the page feeds over the scanner, (a narrow strip of glass that runs across the width of the page along the feed path) the wet liquid paper comes off on the glass as a thin line and dries. Thereafter, when copying, scanning or sending a fax, the scanner light does not go through the liquid paper streak and the result when printed is a thin vertical line that runs the full length of the page. If this is the cause you will also find that faxes you send to other people will also have this line (although faxes you receive are not affected by this problem with your machine).

To fix the problem: follow the path that the paper travels when sending a fax or making a copy, until you find the scanner (narrow glass strip). Take a clean, soft cloth and a small amount of methylated spirit (or white spirit) and remove the now dried Liquid Paper from the glass. Clean the whole strip ensuring that the glass is left clean and dry.

Black line going down the middle of the page


lift the auto feeder and clean the scanner glass that your pages scan across -it is dirty. You can make a copy afterward and this will tell you if you have solved the problem.

Paper has dark marks down middle


If you make a copy, does the copy have dark areas down the middle of the page? If so, remove the toner cartridge and gently roll it around to redistribute the toner inside, maybe even replace the toner cartridge if you've had it a long while. If you still see unevenness, you may need to have the machine looked at.

If the copies you make on your machine look fine, then I would suspect that the person sending you the fax has a dirty scanning element. Check with them to see if they can clean the scanning element and it should improve the fax quality.

HORIZONTAL Lines on faxed/scanned pages.


I've seen this before. Since the printer portion is working fine that points to the scanner mechanism as the culprit. There are two things I have seen cause this. 1) If the line is a perfect rectangle all the way to the edge of the page then the light bar itself is dying and there isn't much you can do to save the unit. Send it in for warranty repair if you have the option. 2) If the line is more like a skid mark like you mentioned, then the paper that is being scanned is not pressing up fully against the light bar. Not enough light is bouncing off the page and the scanner can't read it well. This can also be caused by a roller not feeding correctly and then bunching up the paper a little bit. I would check the rollers for wear or something being off center. This can sometimes be caused if the machine has ran a high volume or thick paper. I would really think the cause would be one of these two since you are getting the marks at odd intervals, if the intervals were regular it could *possibly* be the drum but as I stated before, with the print function working right, I doubt it.
