Lines across scanned images

SOURCE: My scanner always scans with blurry lines across scanned images from it

Hi,

I believe that you are trying to scan via HP solution center.
Did u tried scanning from Scanners and Cameras in control panel, and did u notice any lines?

If u get the same lines, we have to remove the USB Composite device and imaging device drivers.

1.Right click on MY computer ->Properties->Hardware->Device manager.

2.You will get Device manager window popping out.

3.Check for Imaging Devices, click on + sign, then u will see "hp photosmart c3100" right click on it and click Uninstall. Then, Scroll down to "Universal Serial BUS controllers".Click on the (+) sign.

4.Check for the "USB Composite Device" and right click on it, click Uninstall.(IMPORTANT NOTE:wE HAVE TO UNINSTALL THE PRINTER'S USB COMPOSITE DEVICE, TO KNOW WHETHER IS THE PRINTER'S USB COMPOSITE DEVICE, RIGHT CLICK ON USB COMPOSITE DEVICE AND PROPERTIES,look for wat location says, Eg -LOCATION : HO DESKJET F300)

5.Disconnect the USB and reboot the PC.

6.Connect the USB after reboot, you will get popup "Found new hardware".Then the Drivers will be installed Automatically.

7.Try scanning.Please let me know after following the steps!

SOURCE: Vertical lines when scanning using automatic document feeder...Glass is clean

It is not in the glass. More than likely it is in the rollers of the ADF feeder. If you open the cover of the ADF feeder you can see there are 3 screws (! is found under another small cover furthest to the back of the machine. Once these three screws are removed you can left the entire ADF feeder from the unit. You will then be able to clean all the rollers. Do not use alcohol as this will dry our your rollers and cause them to eventually crack. Just use soap and water to clean the rollers. Then reinstall the ADF feeder assembly back on the machine.
