Pull out the laser cart and see if you can locate a sheet from that end.

Orange light blinking, cleared paper jam, changed printer cartridge, won't print subsequent documents.


Double check all doors/ rollers for small pieces of paper stuck in the rollers. Sometimes just opening the door in question and closing will reset the paper jam sensors. Paper jams can be smaller than your pinky finger nail. So double check,

Comment if it still isn't working.

    Paper was jammed, it split. We went through back of HP Officejet7310 to remove paper. After we removed it three lights came on and kept coming on without stop constantly. Auto Answer, Exclamation, and...


    FLOWO THE STEPS

    1. 1
    Switch off the printer and disconnect the power supply. Allow any residual charge to fade away before putting your hands or metal tools inside the chassis.
    2. Step 2
    Pin down the exact location of the jam. The three hot spots for a jam are the paper tray, anywhere between the feed tray and the print carriage, or between the print carriage and the output tray.
    3. Step 3
    Take off the front paper tray if the sheet got stuck while it was still in the front area of the printer. If the sheet jammed here, you should be able to see most of the paper.
    4. Step 4
    Pull on the sheet with both hands and steady pressure. Do not tug as you might rip the paper, leaving a chunk of it deeper in the machine.
    5. Step 5
    Open the back panel to reach paper jammed between the feed tray area and the print carriage of the all-in-one printer. Carefully remove the jammed paper from the machine.
    6. Step 6
    Use the carriage access door to reach a jam further inside the all-in-one printer. You may need to move the print carriage out of your way to clear the jam.
    7. Step 7
    Return any access panels to their closed and locked positions. Plug your printer back in and flip the power switch.

    The printer is constantly sending a message- 'paper jam'


    HP Officejet 7200, 7300, and 7400 Series - 'Paper Jam: Clear jam, and then press Enter' Message Displays on the Control Panel Display
    Issue
    During printing, the paper becomes stuck in the all-in-one and the error message 'Paper Jam: Clear jam, and then press Enter' displays on the control panel display.
    Solution
    Use the following instructions to clear a paper jam from the product:
    Step one: Check for and remove any loose paper from the In tray
    Do not try to remove jammed paper from the In tray. First remove any loose paper from the In tray to avoid worsening the jam.
    CAUTION: Always try to remove jammed paper from the back of the printer first to avoid mechanical damage.
    Step two: Clear the jam from the back of the printer
    Follow these instructions to clear jammed paper from the back of the product. If the product is equipped with a two-sided printing accessory, skip to that section.
    Remove the rear access door to clear the paper jam

    1. Remove the rear access door by pressing the buttons on the side of the door and pulling it toward you.
    Figure 1: Removing the rear access door
    Rear access door
    2. Gently pull the jammed paper out of the rollers.
    WARNING: If the paper tears while removing it from the rollers, check the rollers and wheels for torn pieces of paper that might remain inside the product. If all the pieces of paper are not removed from the product, more paper jams might occur.
    3. Replace the rear access door. Gently push the door into the all-in-one until it snaps firmly into place.

    Remove the two-sided printing accessory to clear the paper jam

    1. Remove the two-sided printing accessory by pressing in the buttons on the sides and then pulling the accessory toward you.
    Figure 2: Removing the two-sided printing accessory
    2. Gently remove any jammed paper.
    WARNING: If the paper tears while removing it from the rollers, check the rollers and wheels for torn pieces of paper that might remain inside the accessory. If all the pieces of paper are not removed from the accessory, more paper jams might occur.
    3. Press the button on top of the two-sided printing accessory to open the door.
    Figure 3: Opening the two-sided printing accessory door
    4. Gently pull the jammed paper out of the rollers.
    5. Close the accessory door.
    6. Reinstall the two-sided printing accessory.

    Step three: Clear the jam from the automatic document feeder (ADF)

    1. Remove the document feeder tray from the product by gently pulling it.
    2. Lift the cover of the automatic document feeder by pulling it outward.
    Figure 4: Lifting the cover of the automatic document feeder
    Automatic document feeder (ADF) door
    3. Gently pull the jammed paper out of the rollers.
    WARNING: In the rare occurrence of a severe paper jam, you might need to remove the face plate from the front of the automatic document feeder and lift the pick assembly to remove torn pieces of paper from deep inside the automatic document feeder.
    4. Close the cover of the automatic document feeder, and then reattach the document feeder tray.

    Step four: Verify that the print carriage can move freely
    Follow these steps to try to move the print carriage.
    CAUTION: Do not force the print carriage to move if it is out of plain view or feels stuck. Forcing it may damage the printer.

    1. With the product turned on, open the print cartridge access door. The print carriage might try to move into the access area. If so, allow it to move to that position.
    2. Without turning off the product, unplug the power cord from the back of the product. Unplug the power cord from the power source. The power cord must be unplugged to allow the parts to be moved by hand and to reset the paper feed mechanism, without the risk of an electrical shock.
    3. Looking in through either the print cartridge access door or the output paper tray, make sure the print cartridges are locked into the carriage and have not come loose. Also, make sure that there are no obstructions under or around the carriage to block it from moving.
    4. Make sure the print carriage can move freely across the width of the product by gently pushing the carriage to the left and then to the right. Clear any obstructions found.
    You may have to reach through the output paper tray to access the print carriage.
    5. Close the print cartridge access door and plug the power cord back to the back of the product. Plug the power cord into the power source.
    6. Press the On button to turn on the product.

    Step five: Reload and test the printer
    After you have removed the jammed paper, make sure the product is still functioning properly.

    1. Reload the product with plain paper.
    2. Peform a self-test by pressing and holding the RESUME button on the control panel until the product begins printing. A test page prints.

    Step six: Service the printer
    If you have completed all the steps listed above and are still experiencing a problem, service the product.

    Turned it on and it says paper jam. There is no


    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


    try this....
    try this, its probably a small part of jammed paper or then theres a problem with the pickup, try cleaning it.

    1. Turn off the printer.
    2. Remove any paper trays. Inspect them for wrinkled or damaged paper.
    3. Also open the back cover of the printer if this model has one.
    4. Open any other doors that give access to the printer's paper path and to the toner or ink cartridge.
    5. If necessary, remove the toner or ink cartridge. Place it away from light/ sun light to avoid damaging it.
    6. If you find a piece of jammed paper, remove it by holding it with both hands and pulling firmly. The goal is to keep the paper from tearing. If several pieces are jammed together, try pulling out the middle piece first to loosen the jam.
    7. If the paper does tear, try rotating the roller gears manually to free the paper. Don't force anything, though. Do this step especially if the jam message comes up repeatedly without any obvious paper jam, there may be a small tear of paper inside.
    8. Ones the printer is free of paper Replace the toner or ink cartridge and paper trays, close any doors you opened and turn the printer back on.
    9. If the printer paper jam message still appears, then there is still some paper in the printer. Reinspect the paper path.
    10. see alternative if the problem is still not solved.



    alternative :
    Load a piece of thick paper, for example photo paper and press the resume button (may be diffrent button on diffrent models) a few times to the printer picks up the paper and puts it through the machine.

    HP 6940 will not print


    Turn the printer off
    Open the back door and
    gently turn the paper roller upward until it clicks. Make sure the door is securely closed. Wait a few more minutes then turn the print back on. I hope this helps.
