vertical yellow lines>

Looks like a hardware problem to me. When the scanner is moving down and a part of it's "vision" is blocked, a vertical line will appear. Did you check the moving "reader" for any obstruction or dirt ?

definate hard ware problem. Needs to go to a bench for a service

Uninstall the scanner and all of its softwate (if you have norton anti virus go itno it and disable auto protect mode) then reboot once back in windows hit ctrl,alt,delete on your keyboard and end task everything except for explorer and systray then reinstall the scanner.


2. If that did not work then go into your BIOS and do the following

turn off power saver mode
set parallel port to ECP

3. Clean the scanner glass make sure there is nothing on it.

4. Make sure scanner is plugged direct to the wall no powerstrips and no surge protectors.

if none of this worked let me know how you have this connected to the pc i.e. Parallel SCSI etc.. also what model scanner do you have ?


if you have an hp 5100 try this

HP ScanJet 5100C Scanner Family - Vertical or Horizontal Lines Appear on Scanned Images, Grinding Noise
ISSUE: Vertical or horizontal lines appear on scanned images. The top lines of the source document may repeat as the image is drawn on HP PrecisionScan. Or the image may appear distorted or muddy. A dark border may appear all the way around the image.

Or

The message "No regions were found during the preview scan" appears when trying to scan. The scanner may make a grinding noise while scanning.

SOLUTION: Unlock the scanner:

Turn the computer off.
Unplug the power cord from the back of the scanner.
Locate the lock lever on the back of the scanner next to the socket for the power cord.
Pull the lever all the way out (toward the side of the scanner) until you hear the scanner unlock.
Plug the power cord back in.
Restart the PC and retry the scan.

First thank you very much for your input to this problem but i must say i have tried all that you had mentioned in your answer for me and i keep hoping that some one will have an answer,
And yes this is the 5100c hp scannar. I still have the yellow vertical lines or what ever you may wish to call it on all scan in colour projects.

at this point then the scanner is probably going to need to be serviced as said before by the other experts

If scanner under 18 months old call HP. Your scanner is about to start "Grinding"

Just what figured (service). Probably pay to just chuck and by a new scanner.  Thanks for the unlucky advice.
