Separate login from scanner detection
If you can access the portal but the scanner is not detected, treat it as a workstation/scanner issue. If you cannot access the portal at all, troubleshoot login first.
Workstation checklist
These checks do not require account information. They help identify whether the problem is USB, browser, driver, security software, or permissions.
Confirm the scanner has power and a stable USB connection.
Restart the scanner and workstation if allowed by your company policy.
Check whether the browser or WebScan component is installed and allowed to run.
Test with another USB port if IT permits.
Ask IT whether endpoint protection is blocking scanner software.
Record the exact non-sensitive error message before escalation.
Escalation notes
For business environments, RDC fixes may require local administrator rights, company IT policy changes, or support from the official provider. Do not install drivers from random download sites.
FAQ
Can this site install scanner drivers?
No. This site only provides a checklist. Use official or company-approved installation sources.
Why does scanner access fail only on one computer?
That usually points to a local workstation, driver, USB, browser, or security policy issue.
