    You must have disloged the paper sensor in the ADF. Open the ADF cover and look for the paper sensor. It is spring loaded and it may have come loose. Also, with the ADF cover openned, try to manuall feed a piece of paper to see where it gets stuck.

    Was the black line showing with the old cardtridge?

    Are you trying to feed throught the ADF (document feeder, but cannot?

    If you cannot feed using the ADF, you may have to clean the rollers. And if the black line shows up when you do feed from the ADF, you have to clean the narrow glass pane on the left of the big glass pane.

Something might be blocking the light from the scanner lamp to fall on the originals. Try cleaning the glass covering the lamp.

If this is happening when copies are made only and not on prints from the computer, lift the top doc feeder lid and located the strip of glass. You should be able to locate a spot of ink or white-out or something else on the glass strip. The scanner for the doc feeder moves the original paper over this strip window to scan it. A dot will appear as a line. Put some Windex or similar glass cleaner on a rag and clean the glass well. Shoot, while you have it open clean all the glass and all your copies will look better.

If it's happening in copy and printer mode (sent from computer), check the toner caridge for damage to the drum. To check the drum, simply flip open the shutter that has the HP logo and part number on it. You'll see a black tab hanging out past the left handle. Move the tag downward to momentarily view the drum. Keep the drum out of direct sunlight or bright lights as they are light sensative.

If there is a line on the drum, replace the cartridge.

Hope that helps you. If so, hit me with a FIXYA. If not click on my user name and let me know what you find so I can isolate it further for you.

Hp 2840 "Replace supplies"

If one of the color cartridges runs out the machine will switch to black only mode. However, I have found no way to force it to continue printing in color mode when any one of the cartridges runs out.

Make sure all cartridge are install and secured into place...(take all the cartridge out and back in ) close front door cover and it will go into cartridge calibration...If not, press the "menu" key and with the arrow go to print quality and confirm with the enter key. Go to calibration and confirm...

Let me know....
