Where is the red card?

Hint 1 of 5:

Actually, I don't believe it's vital to get the red card, but if you're
stuck, look for it.

Hint 2 of 5:

Once you get past the second conveyor door and have to jump over some more
muck, look to your right for another room with Imperial bad guys.

Hint 3 of 5:

Just jump into that room to get the red card.

Hint 4 of 5:

You can exit with the card.
