Re: I have a dark line across copies
Whats the make and model of the copier?
One culprit might be the drum. If you can take a look at the drum from your copier and you see black lines on it. It could be scratches on the drum or it may need a new cleaning blade to clean the toner off the drum.

When copying from the feeder the page is fed across a fixed point at the head of the flatbed. Any dirt etc on the glass at this point can present as a dark line running vertically down the printed page. When copying from the flatbed, the scan head is moved down the page so any dirt on the glass will only appear as specs. Try cleaning the glass, especially at the head of the flatbed where the feeder is loading the page to be copied.
Does this happen when you print, or only when you copy? If you print out a configuration or user settings page, or print a page from the computer, is it also missing two vertical lines of print or is it only when you are copying?
If it happens when you print, you may need a cleaning, or you may need to replace the toner or drum cartridge. If it's an inkjet machine, there's a possibility there is some ink or grease on the encoder strip (a small belt-like plastic strip that goes through the print-head carriage).
If it only happens when you copy, test both the flatbed and the document feeder. If it happens on both then you may have a bad scanner. If it only happens when using the document feeder, you likely have some whiteout (or something) on the glass. When you make a copy in the flatbed, the scanner moves across your document. When you make a copy using the document feeder, the document moves across the scanner. In this case, if there is anything on the scanner glass (like whiteout) your copies will be missing a vertical line of print data (it could be white if there is whiteout on the glass, or it could be dark if something dark is on the scanner glass).
Usually you can lift the flatbed cover and look at the glass to see if anything is on it (usually at the left side of the scanner). Clean the glass, first with alcohol to remove the obstruction, and then with a little windex to remove anything the alcohol may have left behind.
if the glass is totaly clean and top servers is not damaged in some way then i will say that perhaps the light. not familiar with the term. Do a scan or copy with the lid on and watch the scan head and see if there is a dark spot there or if it will show something on the glass.
Does this happen both when copying and printing? For printing solution, try another toner cartridge. If lines continue to appear when copying (primarily through the automatic feeder) then lift the auto feeder, and clean the glass -mainly the narrow piece on the left side.
It depends... never use a Reman cart in these machines... only use sharp...especially if the machine is under warranty. Does this happen when, Using the Doc Feeder When making copies from the Glass Or when you print from a computer (assuming you print from a PC) If you print something and this happens then it is inside the machine Probably toner or developer dumping... Take a few pieces of large white paper and cover the entire glass surface... make a copy is the line there? If so see the answer above... if not then close the top and make a copy with no paper on the glass... is that black line there.. If so then your top needs adjustment... One more test If you make a copy using the doc feeder, this black line only occurs when making copies with the doc feed, clean the **** glass, and try again...
Do the black lines only show up when useing the adf???? Or do they show up on both the adf and the copyboard glass??? If it is only when using the adf...... The fix is easy.... you have to clean the smaller piece of glass that is to the left of the copyboard glass with windex or rubbing alchola. If it is with both you may need a new drum and blade or a new ufr... Good Luck
I will give you all the reasons I can think of.
1, If the line is only there when running through a document feeder and not there off the glass. The small strip of glass directly under the document feeder is dirty.
2. The drum has a scratch on it, or the cleaning blade is not cleaning the drum properly. Would require that cartridge replacement.
3. The fuser roller may be work in the middle. You would notice some reprinting , or ghost copying if that were bad.
4. Less likely would be some piece of fuzz in the light path, or a small piece of paper or tape in the paper path smearing the ink across the page.
If your machine prints, see if the line is on a print, if its on a print and not on the copy then it is scanner related.
