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

We have a black line down the center of all copies...

If the problem only happens on copies or sent faxes then no it is not your drum. There is something on your scan glass. My guess is you are getting the line on your copies when you run the original through the document feeder. If you get lines through the document feeder but not on copies made off the glass then it is a dirty scan glass. There is a thin glass strip where the document feeder feeds the original. Usually something like white out that did not dry smears off an original and ends up on this thin strip of glass. Scratch it off with your finger nail and use some glass cleaner to resolve the problem. The scan glass is about 1/2 an inch to an inch wide and will be on the same side of the machine that the copier feeds the originals in on

Black lines down on printed page

This is caused by dirt/debrise on the ADF (automatic document feeder) scanner glass. You need to open up the feeder where your originals are fed in and look for a strip of glass that runs from front to back. It is about an inch or so wide. You need to clean this glass to get rid of the lines. Some models have this glass just to the left of the large main glass, but in your case I beleive it is in the feeder itself.
Good Luck.

Blank line down left side of outgoing fax or feeder copy

The most common cause of blank (void) lines on a scanned document is from whiteout on the glass where the page is scanned when using the document feeder.
If there is a clear mylar sheet on the bottom of the document feeder, the whiteout may be there instead.

If there was dirt or a dark smudge on the glass (or mylar), it would show up as a black line, but whiteout is white, and shows up as a void (blank) line.

Vertical lines about one half inch apart down center of the page when fed through the document feeder. No problem with fladbed copying or scanning.

If you open to document feeder and look at the glass when scanning via flatbed, just to the left will be a smaller piece of glass. That is the glass used when scanning through the feeder. Clean that glass as there is probably a couple of spots on it.

Black line when using feeder

Not familiar with this model in particular, but if you lift the document feeder, as if to place an original on the glass, there is either a narrow filter glass on the left of the main contact glass, or in many cases it is attached (clipped on) and lifts up with the document feeder cover. Clean this glass. If it is clipped on to the cover, remove it, and clean both sides. I hope this helps.

Please rate solution :)
