How to release tray on dvd2040

First, remove the paper tray from your printer. On a Canon printer, this is done by pressing the release clips located on the right and left side of the paper tray. On an HP printer, press the release button to remove the paper tray. Once the paper tray is released, locate the broken paper tray clip. This clip is usually a plastic piece that is clipped onto the paper tray. Using a pair of needle nose pliers, carefully remove the broken clip from the paper tray. Once the broken clip is removed, carefully inspect the paper tray to make sure that the area where the clip was attached is clean and free of any debris. Next, locate a replacement paper tray clip. You can find these clips online, or at a local office supplies store. Using the same needle nose pliers, carefully attach the new clip to the paper tray. Make sure that it is securely attached to the paper tray. Finally, re-insert the paper tray into the printer following the same instructions used to remove it. Once the tray is inserted, test its functionality to ensure that the new clip is securely in place.

Some have a tiny hole in the tray front to manually release it/push the tray open.

pls have a look on picture you may find several mechanism involved to eject tray check might be bent or tension spring in not good condition

Spray trays with pam. Usually does the trick

Check if the tray got a belt and change it

If the tray does not open when you press the eject button, try to manually open it. To do this:

1. Unplug your Xbox console from the power source.
2. Locate the manual release button on your Xbox console.
   
   For most Xbox consoles, the manual release button is located in a small pinhole to the left of the eject button under the disc tray.
   
   For some Xbox consoles, the manual release button is located under the disc tray. It can be under the "O" or the "B" in the word "XBOX" that appears on the tray.
3. Insert a straightened paper clip or other small tool in the hole at an angle to the left. Gently push the paper clip to try to press the manual release button and partially open the disc tray. This may take several tries. Typically, a thin paper clip works better than a thick paper clip.
   
   If you insert the paperclip in the hole and find an obstacle, this indicates that your Xbox console's manual release button is located in a different area of the console. Look under the "O" or the "B" in the word "XBOX" that appears on the tray. If this is the case, insert the paperclip under the "O" as outlined in step C. If you find an obstacle, insert the paperclip under the letter "B”. The manual release button is located in one of these three locations.
4. After the disc tray partially opens, pull the tray with your fingers to fully open the tray

Hope this will help u.

You can manually eject the tray, you have to take the faceplate off to do this, but here is the instructions:

http://www.llamma.com/xbox360/repair/manual_eject_xbox_360_dvd.htm

try this

Insert any disc into unit, press the PBC button on your remote, followed by the play button, the PBC function should open the higher level menus thus allowing you to change RCE coding

there is a small hole in the front of the tray that will accept a straightened paper-clip. gently insert the clip and the tray should release. if the cd/dvd disc is dislodged from being flat in the tray, it may not come out. you might need to open the cover and manipulate the disc to get it back flat in the tray. a good first test is to see if the disc plays. if it does, it is in the tray correctly and should be easily released with the paper clip. the try might work after you release it.
another possible first try would be to gently push inward on the tray after telling it to release. if there is extra tension on the tray it could cause the mechanism to not release. freeing the tension on the tray could be all that you need to get the 'unlock' to release. (kinda like trying to open a door when someone is pushing it very hard against the lock mechanism. it wont be able to move).
good luck
