Question about HP DeskJet 940c InkJet Printer
Clear the paper jam. Then with a cotton pad and some alcohol, clean all the rollers that you see. If you can get to the rear of the printer, make sure that there isn't any paper residue back there, and also clean the rollers in the back. There is a platen (rod that the print head slides on) clean that too.
Then carefully clean the strip in front of the print head.
Also, never move the print head while the power is on, it will cause the unit to get off it's alignment.
Let me know what results.
