HP 6313 scanner driver for win7 64bit

[ponder]

I have my HP6313 All-in-one printer/scanner/fax/copier connected via the LAN.

Win7 autodetects and installs the printer driver but not the scanner driver.

Now HP has the 363MB HP Photosmart and Officejet Full Feature Software and Drivers package on their website but I don't want all that bloatware.

Any ideas as to the driver only files?
