Black line when scanning or copying from top feeder

I think there must be something on the rollers or something causing a problem. If i scan or copy from glass, all is well but when i run a paper through to either make a copy or scan, i have a black line on one side. thanks.

Please check whether their is any thing on the glass of the scanner or there might be some dust or something might be stuck the glass that's why this problem occurs. so kindly clean the scanner glass with neat and clean cotton with some spirit on it and this will help you resolve your problem.

Horizontal line on printed page


When you use the flatbed the copy is perfect because the ccd sensor is under the glass cover and obviously is free form dust/ dirt.
On the other hand if you use the feeder the ccd sensor is located in between the roller assembly (not sure exactly for this model).
This means that the page is scanned by the ccd in the feeder, any dirt on the ccd will appear as a black line. I assume that you are feeding papers from the side and not from the top that is why you get a horizontal line.

A quick test to see if the ccd sensor is dirty is to feed the paper from the top side to the feeder. If you get a vertical line it is a proof that your ccd sensor needs to be cleaned.
The worst case is that the sensor in the feeder assembly has a tiny spot that is damaged and it is causing the black line.
So , first try the test, then open the feeder assembly, locate the ccd and clean it. Hope that this helps.

My HP Officejet 6310xi displays a vertical line when copies are fed through the ADF and when sending faxes through the ADF, the same problem occurs. What could be the cause?


Open the Top Feeder Cover
Clean the Roller with lint free cloth.
Lift the Roller a bit up and you will find a glass strip underneath the rollers
Clean the glass strip with cloth and close the feeder
Try scanning or copying. it should work

HP OfficeJet J5780 Vertical Black Line Prints when copying or scaning only. Cleaned rollers and changed black ink cartrigde. Still problem.


Have you tried cleaning the document feeders Scan Glass? (small glass under doc feeder ~ 1" by 9") Most times there is dirt spot on this glass, causing a shadow on scans and copies.
Try copying from the large glass by lifting doc feeder / platen cover and manually placing original. If no line copying or scanning manually from large glass, then small scan glass is deffenitely the culprit. Hope this helps.

Black vertical lines in copies


You need to clean the glass. Open up the feeder and you have a large piece of glass for scanning and to the left a smaller piece of glass that it uses to scan from the feeder. Clean this smaller piece of glass; even the slightest smudge can leave a black streak.

A line appears down the length of the page on all copies, printing and scanning. How do I get rid of the line?


All you need to do is clean the top feeder which opens into two parts. make sure you clean the black rollers as well as the small strip of glass you will find when you open the second part of the top feeder . don't be afraid to pull open the top feeder it won't break

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.

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.

Black line on document when I scan from platen or ADF or scan to save as PDF.


As a tech I've never seen that happen. from the doc feeder only Yes, not both the feeder and the glass but not show up when you print from the computer ?????????

For sure there is a dot or something on the small strip of glass, only when you do it from the feeder.
the reason is that the document is moving and the dot on the "small" strip of glass now looks like a line to the copier.

You said it also does it when you lay it down on the glass !!??(platen) that should of indicated the drum has a ring around it, but since it doesn't come out on the PC copy then the glass must have a line on it.

Lines on copys when i feed through top feeder


There is a small strip of glass under the feeder.Not the main glass, but look where the lamp is sittting in the start position.
You have something on that section of glass.
It may be very tiny, but that is what causes that. Best way I have found to get that clean is with some alcohol and just a plain piece of copy paper crumpled and used as your cleaning towel.
The reason it is there only when you copy through the feeder is this. When you copy off the glass, the lamp moves and scans the original end to end. So a spot is simply a spot.
When you run through the feeder, the lamp parks and the document passes over the lamp scanning that way. So any mark between the lamp and document will repeat and be line down the page.
