I'm sorry I don't understand the scam. How did they make the cashier believe the newspaper was actually cash?
ATMs don't scan a deposited check or cash. They wait for someone in the bank to open it and determine whether it is legit, then the account is credited. But after a while your account becomes "trustworthy" and any deposits are credited to the account before it is checked.
You deposit the notes and the machine scans and count everything you deposited and gives you the number. If you agree, your account is credited.
I guess you could design fake notes that pass just the ATM...
