Re: hp 2840 laser printer
Are you feeding in the copies from the Automatic Document Feeder? Open the top of the flat bed scanner and look to the left you will see a small piece of glass that is used for the ADF and then you will see a large piece of glass that is used for the flat bed scanner. Clean the small piece of glass used for the ADF and let it dry before trying to use the copier again. Test the copier and see if the gray line is still there.

If I am copying or printing from the computer, the printer will only print the right side of the page. ... something obstructing the laser scanner blocking that side of the media path.
Clean the adf scanner glass. This is the thinner strip of glass that is just to the left of the large original glass. Just lift up the top feeder and look to the left side of the glass. Clean this strip of glass with a soft cloth and some glass cleaner. Sometimes whatever is stuck to the glass is hard to get off so keep at it till it goes away. Another tip is if the line is in the middle of the copy then the "spot" to clean is going to be in the center of this strip from front to back. If the line is to the left side of your copy then the spot is going to be towards the front side.
Good Luck and Than You for using Fixya
hello does the grey line appear if you scan true the "upper" scanner.(set paper on top of printer and sscan it that way)? you should also clean the smal slim glass that is at the side of the big scanner glass. also try to remove all cartridges and tilt them side to side several times. then put them back and test your printer.
