Morgansaki,

You have a dirty scanner lense. when you lift the top cover, as though you were going to do a copy from the platten glass, you will see there is a smaller glass to the left hand side of the scanner. look very hard at this glass and you will see there is a dirty mark on the lense. clean the cglass thoroughly with some quality window cleaner and you will find you line will go away.

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.

The receiver of my FAXes says that there is a black line down the middle of each page. The FAX is a good copy-clear, etc.... but this line has to go. What can I do? Thanks, Donna

Dear Donna,
When a document is scanned from the top portion of the printer, it will loop around and output from underneath. The scanning glass on the far left side will have some debris on it. Lift the the lid exposing the glass portion, inspect for "stuff" on the glass, perhaps pen or white out. You can use a mild soap and lightly dampened cloth to remove any debris.
Good Luck,
Pre

My HP 7210 puts a line down the middle of the page, but there isn't anything on the glass. I think it is on the light, how can I check it?


I am assuming that you are talking about scaning or copying somethign when you mention glass. The line can be from memory or a driver, Try setting the scan quality down to see if it goes away.

Black line is present when copying document; not


This sounds as if you have some ink/contamination on the small scaning glass that sits to either the left or right of the main glass on the copier.(Depending on the model/make)As your original is scanned over this thin piece of glass the scanning device will see any spots and this will result in a black line down the page.Please clean the glass with a soft rag.

Black line down the middle of scanned documents.


Try leaving the cover open and run a test scan, once with a fresh sheet as the item to be scanned and then a second time without anything on the table.  You may see what is blocking the light source or possibly a defect in it.
Scanning is done left-right, left-right across the width of the page and the vertical stripe indicates that the blockage is present during each scanned line.
In servicing copiers and multifunction machines, I have found a number of curious contaminents, one of the most annoying was a moth, still alive, that would randomly sit on the lamp, causing some pages to come out OK, others not. 
If your copies and printouts are coming out fine, then only the scanner can be at fault.

Scanning multiple pages


Hi there

This could be one of many problems, i will tell you a few solutions that i know of, check the lid and see if there is a bulge in the middle of the lid (is the lid uneven in anyway?), if it is, i would suggest that you return your printer to the place where you bought it. This could also be a setting on your printer, the setting could be to scan a book or to scan two smaller pages.

If you would like a manual on how to sort this out (if the problem persists), please e-mail me at dustin_ellse@yahoo.co.uk

Kind regards and good luck
