Question about HP LaserJet 2420 Printer

1 Answer

HELP Had a paper jam. We were able to retrieve the paper but in the process pushed the green button on left side inside the first paper tray. I believe this caused some type of flap to drop down inside the printer which doesn't allow us to put the tray back into the printer. Any solutions? Thanks

    Paper jam


    The way you describe your error, it seems that there is still some residual paper stuck inside the printer that may cause subsequent paper to be mis-aligned.

    Paper jams can be tricky to solve. The paper is usually stuck inside the printer mechanism so even if there is no visible paper jam, you will still get the paper jam error. Try this:

    1. Turn off your printer
    2. Open all trays and remove any paper stuck there
    3. Locate the button to open the printer, open it and remove any paper stuck there also.
    4. Repeate the above step for all buttons that you can find to access the inside of the printer
    5. Close all doors and put back all trays
    6. Turn on your printer

    Paper jam at B2


    remove the paper tray or all paper trays that you have.
    To remove the a tray first you should pull it towards you the most you can than by pulling towards you and in the same time you should lift it up.So again i will explain the procedure, first when is pulled to the max out of the copier you should lift it up for some 45 degrees and than pull it toward you. When you will remove the paper tray or trays inside of the copier where ware the paper tray on the right side of the inside should have some piece of paper which is stuck there. After you will remove the piece of paper the copier should not jammed the paper in B2.
    Also see do the paper in the tray is putted as most close to the right fence of the tray, also see do the right green leveler is also closest to the paper in the tray. If the paper on the left and right side of the upper named fences is loosen than the rubber on the right side of the tray will not be able to pull up the paper in the copier when it will need to do it.
