I received a "Calibration failed" error message when attempting to calibrate my scanner, why?

Description of Solution 200000025011

NOTE: XXX represents your scanner’s model number

During the calibration process the calibration sheet, with the large black bar facing down, should scan with a back and forth motion and finally move to the input slot.  If after this, the calibration fails more than likely the calibration process was unable to write the calibration data file to the Documents and Settings\All Users\Application Data\Brother\DSmobileXXX folder.  This can be caused by two different situations.  Both of which can be corrected by de-installing the software and driver then using the Administrator’s account install the driver, the software, and calibrate the scanner.  Or you may follow the steps below.


I. First the user’s account that is being used to calibrate the scanner should have Full Control permissions allowed. 

1. To do this we will navigate to the folder by hovering over the Start button and click the right mouse button then click on Explore

2. The contents of the local drive are normally on drive C, if not double click on the local drive. 

3. With the drive contents displayed locate the Documents and Settings folder, if the folder contents are not displayed double click on the folder. 

4. Using this process open the All Users folder; then open the Application Data folder, if this folder is not present please see below; then open the Brother folder. 


If the Application Data folder is not present when viewing the All Users folder,

a. with the All Users folder open click on Tools in the menu bar, and then click on folder options

b. With the folder options popup box open click on the view tab. 

c. With the view tab open, In the advance settings under the Hidden Files and Folder icon, click on the Show Hidden Files and Folder radio button and click the apply button then the OK button.

d. The Application Data folder should now be visible.  Open the remaining folders as described above.


5. Hover over the DSmobileXXXfolder and click the right mouse button or hover over the area that shows the contents of the DSmobileXXXfolder and click the right mouse button.

6. From the popup menu, you can now click on Properties and then in the popup box click on the Security tab. 

If the Security tab is not present

a. Open My Computer

b. On the menu bar click on Tools and select Folder Options

c. Once the Folder Options box appears select the View tab

d. In the View tab scroll down to the bottom of the Advanced Setting list and uncheck “Use Simple File Sharing

e. Click the Apply button then click the OK button and return to the DSmobileXXX folder in Step 5 above.

7. Once in the Security tab ensure that the user’s account that you are using is highlighted in the users name area.

8. In the permissions area, the allow check box should be checked for the Full Control permissions option.  If it is not then check the allow check box and click on the apply button then the OK button. 

9. It is now time to try calibrating the scanner again.


II. There is another possibility that can stop the calibration processes from completing successfully.  If the user’s account used to install the software and driver did not have full administrative control when the install was performed the calibration process will fail. 

1. Just as the permissions on the user’s account was changed above, when in the DSmobileXXX properties box select each user and ensure that the Full Control permissions allow check box is checked.  If it is not checked then check the allow check box, click on the apply button and then on the OK button. 

2. Do this for each user. 

3. Try calibrating the scanner again.


We are changing the properties on a specific folder.  Please ensure that the path of the folder is Documents and Settings\All Users\Application Data\Brother\DSmobileXXX or there will still be problems


If after completing these steps the scanner does not complete a successful calibration call Brother Customer Service at 1-877-276-8437 Monday through Friday, excluding holidays.
