after scanning one page .. do not save the page but choose "add another image /page option " and scan accordingly.. and save the entire document after you are done with the scanning of all the pages.

The rollers that pull the paper through could need a cleaning. With general usage these parts do get worn down. By having your printer cleaned by certified technician it would resolve this problem.

If line is vertical.

Try scanning a bigger document. Use a blank page big as the scan capacity and scan the blank page.

If for example you are using an a3 scanner, scan a blank A3 page.

When scanning blank page set resolution to an high value, so that you does not lose pixels.

Check scan result, and explore the whole document using zoom to see if the line is still present on the test scan of the blank page.

If there is still the line, then it is either a scanner dirty, probably inside glass, or a dafective sensor on CCD sensor array.

If there is no line, then the problem is usually depending on the software.

In that case uninstall the software and install it again.

If that is not enough to fix the problem, try uninstalling software, doing a system restore to a date before the problem started , and then installing software again.

If the line is horizontal , that is usually a loss of power on the high voltage to lamp.
Try reinstalling software first, if that does not fix the problem , and line is horizontal, then it is fault mentioned above.
Horizontal lines at the end of a document may also be caused by faulty scanner control board, or scanner going out of memory.

try reinstalling the scanner softwares and if this doesnot help do a master reset of the scanner

If you are scanning using the Auto Document Feeder be sure to clean the glass where the documents get scanned. A small speck will cause a line down the page. On HP there is often a narrow strip of glass on the left side of the platen glass.

first of all try to make a copy..when you make a copy if you get lines..then clean the scanner glass and the rollers..if its still the same..connect the printer directlu to the wall outlet and then check

Try to use Compact PDF or a lower resolution.

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.
