HP 3570c scanner software for Leopard and Snow Leopard

Update: The instructions below probably don’t work anymore. The installer requires (?) Rosetta, which Apple has deprecated as software companies had their 10 years or so to port software to be native on Intel. If you still have this scanner, I recommend you recycle it and get a $50 Canon scanner, which will have better image quality and save you hours of frustration.

HP doesn’t officially support 3570c on OS X 10.5 nor 10.6, but I’ve found the software is installable once you work around bugs in the driver installer. The software is prone to crashes, but tends to do it’s job on my machine the next try after the crash.

DISCLAIMER! WARNING! Installing unsupported software on your Mac can cause severe problems. Please do not follow these instructions. They worked for me, but might not work for you.

1) Download this: ftp://ftp.hp.com/pub/softlib/software5/COL10835/sj-31472-2/COL10835a.dmg
2) Mount DMG
3) Right Click the Installer and select Show Package Contents
4) Navigate to Contents/MacOS/Sub Installers
5) First install the “HP Scanjet 3500”, “HP Scanjet Scanner – Common” and the “HP Scan Pro” packages
6) Go to /System/Library/Extensions and delete “hpPlugInInit.kext” (why does a scanner want to install a kernel extension which isn’t even needed, is beyond me)
7) Do not restart your computer immediately, as OS X rebuilds your kernel
8) Done, use the HP Scan Pro application Hewlett-Packard folder under Applications

With this method, in addition to working in both Leopards, you don’t get any of the useless crap the standard installer wants to put on your computer. Snow Leo will probably prompt you to install Rosetta during the installation.The only reason I’m keeping the HP is that it still works for the little scanning I’m ever doing, so I can’t justify getting a new one (from some company that is not HP). I guess I might have been happier if the install hadn’t worked for Snow Leo.

    Hi Sulka,

    thank you for your walkthrough. I’ve tried it but unfortunately it won’t work with my Snow Leopard 10.6.8

    How long do you suggest I should wait for OSX to rebuild the Kernel before I restart?
    Do you restart OSX first and then start the HP Scan Pro application or the other way round (I’ve tried both ways but knowing how you did this might still help)

    Thank you in advance

    PS
    Any other suggestions how I might get the scanner back to work?

    Dump the sucker. You can get a much better machine at a fairly low cost. I personally regret purchasing the scanner in the first place – the software is awful, the hardware is slow, and there’s much to be wished on the image quality of the scans. If I had to choose now, I’d got with a Canon, probably the Canon CanoScan LiDE 700F model.

    I think this method might work only if you have Rosetta still present in your Snow Leopard installation. A fresh/clean install of Snow Leopard from the disc does not install Rosetta. However if one upgraded from Tiger through Leopard to Snow Leopard then the Rosetta PPC emulator program is retained and you will find this description works, in addition to previous “PPC only” programs like Microsoft Office 2008. Another example of the computer software and hardware industry forcing consumers to throw away old software and hardware and buy all new stuff.
