With an older (HP Scanjet 3300C), I have nothing to lose by ''learning'' to open the case myself in order to clean the ''fog'' off the bottom side of the scan-plate-glass....if i break something... fine.. goes in the trash....... but i would hope someone out here knows the secret to opening the case without causing irrepairable damage... I have already discovered the several ''TABS'' along 3-sides of the printer that i can deflect with a ''slotted'' screwdriver to separate the case.... BUT.... then my access is Thwarted by unknown physical ''locking mechanisms'' preventing full separation of the upper / lower halves of the unit.... does anyone out here know what is preventing me from opening the top? part of the case (nearest the hinges)????????????????
I recently picked up a SJ 3300Cse and have the same issue.
On mine, on the top of the scanner near the hinges there are two small white rubber peices that are very well camoflaged. If you remove them you'll see the two screws to open the hinge side of the case.

My 3300C is back from dead. It's ALIVE!!!!
I am not a geek - just a stupid gene cloner/researcher/academic faculty/administrator (I have never changed oil in my car). The steps I took are as follows (the order is important):
1) Go to "http://www.ellert.se/twain-sane/" and you will see a scary table. Do not get intimidated. You will only download "packages" under the system your mac is running (check "About This Mac" under apple). Forget the rest.
2) Open "Libsub - binary" and install it. Then open Libsub SDK and install it.
3) Open Sane Backends - and install binary and then SDK.
4) Open Twain-Sane Interface and install it.
5) Open Sane preferences and install.
I then restarted my computer (may be not necessary) and opened Photoshop - under File>Import, I had a new option "SANE...". It found the scanner and presented an extremely funky window to adjust coordinates some choices. Don't mess with coordinates, choose "Preview" instead. Give some time for scanner to respond. A few groans later preview is presented next to the funky window - adjust the coordinates and scan :-)
I had the same problem and was having no luck with suggested solutions from HP. But the following procedure did work for me. It disables WIA, the built in XP scanning software. See http://forums13.itrc.hp.com/service/forums/questionanswer.do?admit=109447627+1280600613997+28353475&threadId=124494
1. Right click My Computer. 2. Click Manage. 3. On the left, click the plus sign on Services and Applications. 4. Double click Services. 5. On the right side, scroll down to Windows Image Acquisition (WIA) and right click. 6. Click Properties. 7. On the General tab, set Startup Type to Disabled. 8. Click OK. 9. Exit Computer Management.
Go to the HP website and under the support section see if there is a windows vista driver available for your model #. If there is then download & install. Scanner should then work. Hope this helps & please remember to rate my answer. Thanks.
