    Hi there
    Firstly you will have to get your paper tray unstuck! You have two sensors on the side of the paper elevator upper and lower those two give you T2 errors! Once the tray is at the bottom again then the T2 error will be gone.

    Then check paper feed tray I check that your connecter of your paper feed tray is plugged in, and check the safety bar under your paper tray is not, bend and that it makes that safety switch all the time.

    Good luck

    Hi


    First check your paper detection sensor in the middle of your paper tray make sure it is working see if it is not come undone, that is the harness from the paper tray to the connector on machine.

    Check to see if your tray lift motor is plugged in, go to test mode 102 and press the paper tray down button, the green one above the feed wheels and see if it lifts.

    T2 is a paper tray safety error this means one of the sensors on the side of your paper tray is made when it is suppose to be open. You will find them at the elevator motor side one at the top and one at the bottom. Swap them around and see what happens.

    Also check the safety bar above your feed wheels and make sure it is not stuck.

    What? HuH?
