Question about Canon CanoScan LiDE 30 Flatbed Scanner

1 Answer

Scanner won't communicate with my Mac

I have a CanoScan LiDe 30 attached to my intel core duo Mac using OSX 10.4.9. I downloaded and installed the latest driver, ScanGear CS 7.2.5, but I get this error message: "Cannot Communicate with scanner. Cable may be disconnected. Check status. Scanner driver will be closed. The cable is connected. I'd appreciate any suggestions.

Lide 60 not working in mountain lion

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


  • 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.)


delete the 'CanoScan XXXX' folder


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


delete the CanoScan Toolbox Application


delete any items named "CanoScan Toolbox"

  • Restart your computer, then empty the trash


  • 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:


CanoScan LiDE 60 driver:


VueScan Software:

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)

Will not work with Mac OS10.6.2. Is there an upgrade?

Try downloading CanoScan Toolbox it is supposed to be compatible with 10.6. Unplug your scanner before installing and then reconnect the usb.

Re: CanoScan LIDE 30 on Mac OS X (Version 10.5.6)

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.

Installing CanoScan Lide 20 / Lide 30 into Mac OS X 10.5.5

I found this scanner at a garage sale today, and had trouble finding this info myself. Finally stumbled upon this site ( )

I'm using it on a Powermac G5 but both the driver and toolbox app say they are univeral binary. Hopefully this gets you up and running too:

CanoScan LiDE 30 on Mac OS X 10.5
This technical help may seem completely out of place on this art blog but after scouring the internet for 3 hours trying to set my 6 year old scanner up on my new MacBook, I found this info half way down a lengthy comments section of a random blog. So I thought I'd post it here (slightly altered) as a message in a bottle to anyone else in need of it.

How to set up CanoScan LiDE 30 on Mac OSX 10.5
Select MAC OS X
Download BOTH:
LiDE 20/LiDE 30 Scanner Driver Ver.
(Mac OS X)

CanoScan Toolbox Ver.
(Mac OS X)

INSTALL CanoScan Toolbox Ver.
INSTALL LiDE 30 Scanner Driver Ver. . Make sure Applications>CanoScan Toolbox 4.1>Plug-Ins is selected as the install location.
You will be asked to RESTART. You should.
When you run CanoScan you can choose Photoshop as the default program to open the image in once it has scanned. You do not need Photoshop to open using Rosetta for this to work.
NOTE: If you want to scan directly from within Photoshop CS3, you need to copy the driver 'ScanGear CS 7.0X' which is found in Applications>CanoScan Toolbox 4.1>Plug-Ins into the photoshop pluggins folder, Applications> Adobe Photoshop CS3>Plug-Ins>Import/Export. You also need to open photoshop in Rosetta mode. Apple + I on the photoshop icon and select 'Open using Rosetta'. I would not recommend using this method though.
Go to System Preferences>Accounts>Login Items and remove both of the following:
