JVC Comcorder in a safemode

Safemode 06 on JVC camcorders usually indicates a problem with the tape transport mechanism. It could be a mechanical issue or an electrical issue. It's possible that the black rubber you found inside the camera was a part of the tape transport mechanism that came loose or broke off. It's also possible that there is some debris or dirt stuck in the tape transport mechanism, preventing it from functioning properly.
One thing you can try is to clean the tape transport mechanism with a soft brush or compressed air. Be careful not to touch any of the delicate parts inside the camera. You can also try using a different tape to see if the problem is with the tape itself.
If cleaning the tape transport mechanism and using a different tape doesn't solve the problem, it may be necessary to take the camera to a professional for repair. They will be able to diagnose the issue more accurately and determine if any parts need to be replaced.

Rewind the tape ?

If the camera becomes damp or cold and brought into a warm atmosphere damp forms in the mechanism which would cause the tape to stick and become damaged or fouled.

leave the camera to warm up for a few hours and the fault should clear.

If not the most common reason is the dew sensor has failed and needs replacing

i had the same problem with my cam JVC GR-DVL309 and i solve it.
HOW!
Eject the tape, reinsert it BUT while the tape is going down to read, push the door with your hand just a little bit to right side just a few seconds while is reading the tape and close the door, (i had done this 2 or 3 times) this way i have solve the E04 Error, now i can record and play with my cam.

There should be a error code,what is that?

JVC has some known faults with their camcorders-- and most of the solutions are outside the abilities of average users. JVC says in this instance, to remove the battery and the charger, and let the camera sit for some period of time. If the camera also has a small battery for keeping the date, remove it as well. Let is sit and then replug it in and see if this cures it.

man just try pushing that place by a small support on its lower side. ( imean below... just the opposite side where it is told to "push here". i hope if you didnt broke its locking mechanism, it will work..
