Canoscan lide 70 stopped working

Guide to installing Canon CanoScan LiDE 35, 50 and 60 on Mac OS X 10.8. Mountain Lion:

FIRST PART: DELETING OLD LiDE DRIVERS AND SOFTWARE

• If this is the first attempt to install the scanner, skip this part

• Trash the following files/folders from these folders:

HD:/Library/Image Capture/Twain Data Sources

delete the CanoScan CanoScan XXXX.ds file

(Make note of any other files that may be in this folder. If other files are present, move them to the desktop for now. Then place them back after successfully using the scanner.)

HD:/Library/Preferences

delete the 'CanoScan XXXX' folder

HD:/Users/Shared

delete the folders containing the name CanoScan, or starting with CNQL.

HD:/Applications

delete the CanoScan Toolbox Application

HD:/Users/YOUR-MAC-USERNAME/Library/Preferences

delete any items named "CanoScan Toolbox"

• Restart your computer, then empty the trash

SECOND PART: MAKING YOUR SCANNER WORK

• Make sure your scanner is well connected

• Download the right driver depending on your Model. Also download the Scanner Software. Copy the filenames and search them via Google. Make sure you download the Canon files from an official Canon domain.

CanoScan LiDE 50 and LiDE 35 work both with the 35 driver:

lide35osx7721en.dmg

CanoScan LiDE 60 driver:

lide60osx11131en.dmg

VueScan Software:

http://www.hamrick.com/#download

VueScan 9.2 (or later) x32 for Mac OS X

Alternative to VueScan: CanoScan Toolbox. I prefer VueScan.

Try your luck with Version 4 or Version 5.

CanoScan Toolbox 4: cstbosx4934ej4.dmg

CanoScan Toolbox 5: cstbosx5014ej4.dmg

• Open the downloaded driver file (lide35osx7721en.dmg or lide60osx11131en.dmg)

• and Double-click the ScanGear file, install and restart when prompted

• Open the downloaded VueScan file (vuex3292.dmg) and drag the VueScan application to the Mac Applications folder

• Open the VueScan application. The scanner should be recognized automatically.

(Alternatively try and install CanoScan Toolbox 4 or 5)

You just need to point the program to where the scanning program was installed. If you just let it auto-load it should be here: (assuming you loaded the free toolbox software)
C:\Program Files\Canon\CanoScan Toolbox Ver5.0\CSTBox.exe
or just look at where the toolbox is installed by searching for the CSTBox.exe file.

Vista is the laughing stock of IT pros everywhere.  Vista is truly the bastard child of Bill Gates.  Go on Canon web site and look for updated drivers to run on Vista or downgrade back to XP, which is more user friendly with peripherals.

hi um i don't know if this will actually work but it did for me, I had 2 problems with the lide 60 scanner-one was a connection/cable thing and another was this "TWAIN source thing" and after installing this:
http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=DownloadDetailTabAct&fcategoryid=351&modelid=11446
i seem to only have one....i think the connection/cable got fixed.
oh well, give it a try anyway :) cant hurt

I was able to install the CanoScan Toolbox by doing the following: MacIntosh HD --> Library --> CFMSupport --> Get Info. Under 'Sharing & Permissions', I added my name & changed 'Read only' to 'Read & Write' .

Problem now: I can't install the LIDE 30 Scanner Driver. I clicked on the downloaded driver & a box opened. I clicked on ScanGear CS Installer, but that didn't work. I then clicked on 'Into Plug-In' --> ScanGear CS 7.0X --> Choose Application --> CanoScan Toolbox 4.1 --> Plug-Ins, but couldn't continue as the 'Open' tab was greyed out. What should I try? Any suggestions would be appreciated.

Your Train source may be your scanner Twain driver. Reinstall the driver.

already install the scanner driver but still can't working properly.

Hi toolpusher

Try going to CanoScan Toolbox > Settings and reset the 'defaults' button at bottom... this will restore factory settings and hopefully fix your problem... The other error message you can expect to get is "unable to scan - insufficent memory, check your **** space' (or something similar)... same fix works for both! ...Have had both messages on mine, sounds like a semi-regular conflict on some sort, but seems to be easily fixed. Good luck :-)

Head for the Canoscan Toolbox and click on "Settings".
Under "select folder where temporary files are saved", click on "browser".
Choose where you want the scanned item to be sent and then click 'OK".
This works for me.

Hi there, yes I did everything per your instructions, Toolbox is installed and it still says, "release the lock switch, detach I/F cable and reconnect. Scanner driver will be closed" and then after clicking on that it says "Unable to open TWAIN source. Please check connection then restart toolbox" I have been to the Canon site and downloaded driver sites and it says everything is working. but when I go to scan it comes up with the boxes I said before. Quite lost at the moment? Thanks Maureen. PS I have unstalled and reinstalled
