I’m not sure whether it is actually plugged into the computer on the desktop next to it or not…
If you have your own laptop, you could probably just roll the cart with the flatbed scanner out to the bowling table in the main CA area, plug yourself in, download the driver, and go to town.
If it is connected to the desktop computer, as far as I know, you just log in with your DMS member id (not your talk id - the one attached to your account.) Be forewarned it may take a LONGGGGGG time for your account to be created. I thought the stupid computer had locked up on me, but after about 45 minutes, it finally recognized me.)
Since that is now a BRAND NEW desktop, I will tag @jast In case he has some special login tips that are ACCURATE vs. the “judy shooting in the dark” method(s) described above.
