Paper Support Arm stuck in

[minimanam]

The arm which comes out when the printer starts printing is stuck in the closed position meaning that any printed pages just fall on the floor.

Can anyone advice how to open the arm manually if the automatic function is not going to work

Hi @inimanam,

Welcome to the HP Support Forums! 

I see that the output tray extender is stuck in and will retract on your HP Envy 4520 Printer. I would be happy to help you and please remember to return to this thread and mark 'Accept as Solution', if I have successfully helped you resolve the issue. If you wish to say 'thanks' for my effort to help, click the 'thumbs up' to give me a Kudos. 

I understand the frustration that you're experiencing. It is possible that the tray extender is locked in the closed position. 

To extract the automatic output tray extender manually.

NOTE: The output tray should be similar to the Envy 7640.

If the automatic output tray extender does not deploy automatically, you can extract it manually.

1. Remove the output tray from the printer.

2. On the bottom of the output tray, move the output tray lock to the unlocked position, and then shift the release lever to release the tray extender.

3. Insert the output tray back into the printer leaving the tray extender in the released position.

If the issue persists and the tray does not extend there could be an issue with the hardware. 

I would do a hard reset to see if that will resolve the issue.

1. Leave the printer on and unplug the power cable from the printer and wall outlet for 60 seconds.
2. Then reconnect the power cable to the printer and wall outlet rather than a surge protector. This ensures the printer is receiving full power and may help this situation.
3. Wall outlet
4. Make sure the printer is connected directly to a wall outlet (don't use a power bar or a surge protector). This ensures the printer is receiving full power and may help this situation.

If you completed all the preceding steps and your product still has an issue, service the product.
