hi gluke
welcome to the forum

u attach all passport pages with anything written on it or with any stamp. You take b'w copies and get them attested.

The scanning part is for the visa application, you get colored scans which dont need attesting but if u scan b/w then u have to get them attested.

If u apply fr ACS online, you anyways have to send them hard copies as mentioned in this thread..

cheers and good luck
