Please note you need an admin account to do this.
There are two likely reasons for this error.
1. Scan to Salesforce isn't installed in your Salesforce organization.
The admin must install the Scan to Salesforce setup app before it can be used in your organization. Get the app here.
2. Permissions for SSCard aren't set for the user.
The users who failed to upload business card data to Salesforce may not have permissions for SSCard, a custom object built for Scan to Salesforce. There are two ways to resolve this.
Option 1: Edit the Custom Object Permissions for each profile
If users have custom profiles, you can edit the Custom Object Permissions of the profiles and apply this to all users. Make sure your users have permissions to upload by going to Setup > Administration > Users > Profiles. Find the profile of the user and edit SSCard in the Custom Object Permissions section.
*Custom Object Permissions can't be changed if a user has a Salesforce standard profile. In that case, try Option 2 or clone the profile and assign it to the user. The new profile will be a custom profile and you can edit the Custom Object Permissions.
**If your organization has enabled the Enhanced Profile User Interface, click Object Settings > SSCard and edit the Object Permissions.
Option 2: Assign Permission Set to users
If your users are using standard profiles, you can assign the Scan to Salesforce Permission Set to uploading of business cards. Go to Setup > Administration > Users > Permission Sets and find Scan to Salesforce. You can assign the permission set by clicking Manage Assignments and then choosing the relevant users.
