When configuring multifunction printers (like Kyocera or Konica Minolta) to scan to a shared folder on a Windows PC, users may encounter authentication or connection errors. This guide provides a step-by-step troubleshooting process focused only on SMB (Server Message Block) issues — no FTP workarounds.

---

📍 Common Errors

• Login Error
• Cannot Connect to Shared Folder
• Authentication Failed
• Printer accepts configuration but fails during scan
• Other PCs and printers can access the share successfully

---

✅ Prerequisites to Confirm

1. Verify Folder Share Configuration

Ensure the destination PC (e.g., PCName) has the folder shared properly:

• Folder: C:\Scans
• Share path: \\PCName\Scans or \\192.168.0.144\Scans
• User has Read/Write NTFS and Share permissions

🔧 Tip: Use IP-based path (\\192.168.0.144\Scans) to avoid name resolution issues.

2. Confirm User Account and Password

• The printer must use a valid local or domain user account
• The user must have a password
• Account must not be locked, expired, or disabled
• Try using:
  • PCName\Username
  • or just Username depending on printer model

---

🧪 Test from Another PC

Run this from another PC to verify credentials:

cmdCopyEditnet use \\192.168.0.144\Scans /user:PCName\Username

• If this fails, it’s a credential or permission issue, not a printer issue

🛠️ Critical Step: Check SMB Version Compatibility

Many printers (especially older Kyocera models) only support SMBv1, but Windows disables SMBv1 by default due to security risks.

🔍 Check SMBv1 Status:

Run this in PowerShell:

powershellCopyEditGet-WindowsOptionalFeature -Online -FeatureName SMB1Protocol

✅ If SMB1Protocol is Disabled:

Enable it only if required by the printer:

powershellCopyEditEnable-WindowsOptionalFeature -Online -FeatureName SMB1Protocol -All

⚠️ Security Warning: SMBv1 is outdated and vulnerable. Only enable it if absolutely required and restrict access to trusted devices.

---

🔐 Check Windows Firewall Settings

Ensure the following rules are enabled on the destination PC:

• File and Printer Sharing (SMB-In)
• Allow inbound connections on Private network

🔧 Control Panel → Windows Defender Firewall → Allow an app through firewall → Ensure File and Printer Sharing is enabled

---

🧾 Summary Table

Area	Check
Folder path	Use full UNC path with IP (e.g., \\192.168.0.144\Scans)
Permissions	Share + NTFS: Read/Write for the user
Credentials	Valid, password-protected local account
SMB Version	Enable SMB1 if required (SMB1Protocol)
Firewall	Allow File and Printer Sharing
Hostname resolution issues	Use IP instead of hostname

---

• SMBv2 and SMBv3 are supported on all modern Windows systems and should be prioritized.
• For older printers that require SMBv1, consider firmware updates or printer replacement for security compliance.
