Uninstall the driver and reinstall the driver. Make sure your driver supports the Operating System you are using.

    There maybe a Scan Panel in the lower right hand side next to the taskbar. Check Startup with msconfig and uncheck Scan Panel. Reboot and try it again. I did this and it worked for me.

    With the scanner connected to my XP laptop via docking station I ran the setup.exe from the Version 2.3 folder under ISIS-TWAIN for the DR-2050C. I tried scanning and got "device could not be locked" error.

    All I did was disconnect the USB scanner (while it was on) and connect it to another USB port on the docking station and it began to work perfectly.

How do you get rid of the Canon DR-7550C -4630 error "The device could not be locked"?


It's usually a software conflict.
If you have multiple scanning programs, the one of them may have it locked. Especially if you have a scanning program that runs as a service.

Installed driver twice for Canon DR-2050c. Still


Pls run checkdisc/scandisk on your Comp. Your OS may be corrupted. Just to verify try scanning by connecting to a formatted newly loaded OS Computer.

If it is application error then follow these steps: Warning: You should not install a version of BlackBerry Device Software that is earlier than the version installed on the BlackBerry smartphone. Doing so could cause the BlackBerry smartphone to malfunction. Before proceeding, make sure that the latest version of BlackBerry Device Software is installed on the computer by completing the following steps: Open BlackBerry Desktop Manager. Click Help. Select About Desktop Manager. Click the Device Software tab. Verify that the BlackBerry Device Software displayed is the latest version currently available from the wireless service provider. Warning: The following procedure will delete either all data, or all data and applications on the BlackBerry smartphone. Back up the BlackBerry smartphone data before proceeding. To perform a clean installation of the BlackBerry Device Software using BlackBerry Desktop Manager 4.1 to 4.3, complete the following steps: Connect the BlackBerry smartphone to the computer and open BlackBerry Desktop Manager. Double-click Application Loader. Click Next to start the installation process. Type your BlackBerry smartphone password, if prompted, and click OK. Select the check boxes next to the names of the applications you want to load, and then click Next. Click Advanced, and then select the check boxes beside Erase all application data and Erase all currently installed applications . Click Next. Select the check box next to Do not automatically backup the application data during the loading process (if prompted). Clear the check box next to Backup and restore applications installed wirelessly (if prompted). Click Next > Finish. When the process has completed, the message The loading operation was successful will appear. Click Close to return to BlackBerry Desktop Manager Note: BlackBerry Desktop Manager 4.3 will display the Delete all application data and Delete all currently installed applications check boxes in step 6 of the above procedure.
