Hi Cathy, no you can't get both the will & the blueprints with one number.
To get the will, as Bennet, talk to Johnson about the will (or will & blueprints) He can give you the will - go to the machine, scan your fingerprint & from what I can remember you can just take the will. (You might have to calibrate the machine to M20 first).
To get the blueprints you need to have a master keycard which you can only get from solving the puzzlebox at Tortoise Security.
As Ray (making sure he has the keycard), once you have both the numbers for the will & blueprints use the master keycard on the machine - choose 'retrieval arm manual alignment', move it to Q24 & click save.
As Bennet, interrupt the conversation in the copier room then ask Johnson (when he's back behind his desk) for another copy of the will. As before scan your fingerprint & hopefully you should be able to pick up the blueprints.
Hope that helps - please say if you need more detail!
