[Star Wars/Alien] How long would it take to infest the Death Star?

A queen Xenomorph is found on a Outer Rim planet.  She is brought in to be tested on.  She escapes and disappears into the DS bowels.   For weeks, she is not found and is laying eggs.   An unsuspecting engineering team is overtaken by facehuggers...  

Assuming a normal infest rate, how long before either the troops kill them off or the station is overrun.   

Also, No Vader or Palpatine are around to use the Force on them.

•The DS came equipped with multiple scanners, cameras, and sensors, that would be able to tell them where all the Xenos are.

This would allow them to send wave after wave of Stormtroopers, all equipped with blasters and grenades, after them. 

If somehow that doesn't work, they can utilize the Blast Doors to lead the Xenomorphs to traps, like a hanger, where they can instantly decompress the room.

•They can use mouse droids to carry explosives over to them

•They can pull a minigun from storage and shred them to pieces.

•Their Helmets would help stop face huggers.

•The Stormtroopers wouldn't care about killing their infected comrades

•They have flamethrowers.

•Darth Vader

Seriously, it would not take very long for them to be rid of this menace. Even with all that, it takes one Stormtrooper patrol to see it, and it suddenly got dozens of blaster holes in it.

Edit: Honestly, the hardest thing for them would be somehow cleaning up the Acid blood after the 
Xenomorph massacre.
