Scanning

Guys, I use HP Deskjet 3515 AirPrinter to Mavericks 10.9.4 beta iMac. But now mentioned that the previously used by my default scanning app in Mavericks disappeared.. Or, i simply cannot find it Just installed the HP software . By it - I can scan, but do not like it, it is very slow. Please advise what app inside Maverick do you use to scan? I would prefer to use the os build in one, instead of 3rd party HP sw..
