Paper Jam on a HP Deskjet 450

This seems to be a fairly common issue on this printer model. The paper will jam just as it passes the exit rollers. Sometimes the paper will skew with just one side feeding and the other side stuck. You’ll see two black rollers at the exit slot of the printer. Sometimes one and more commonly both rollers will just not pick up the paper anymore and cause the paper jam. If you’re up to it, pull out the screwdriver and unscrew the case and then pull apart the top and bottom plastic casing. My first try at this resulted in breaking one of the plastic tabs located internally at the front of the case. It is not the most user friendly device to take apart. The objective is to get access to the two black rollers at the exit slot and swab them with alcohol. If you get the case open, go ahead and clean the rollers really well. If you prefer not to open the case, you can try alcohol on a q-tip, print a test page without paper loaded and when the rollers start turning, quickly swab and clean the rollers. You might have to do this a few times to get it clean. Once the rollers are clean, it should once again paper feed without jamming.
