Konica Minolta SMB Error 16711701
The C287/C227 reached an SMB destination but could not verify the SMB signature used to protect the session.
Error meaning
SMB signature verification failed.
This meaning is tied to the reviewed family/platform and subsystem below; do not reuse the number or wording by itself on a different printer family or protocol.

- smb-16711701
What usually causes it
- The SMB server's signing behavior does not match what the printer expects for this connection.
- A server security-policy update changed signing requirements or negotiation behavior.
- The connection is reaching a different SMB server, NAS, or DFS target than the one previously used.
What to try
Confirm the failing destination is SMB Scan to Folder
Keep this code in the SMB context. Do not apply the same digits to e-mail, FTP, LDAP, or another printer family.
Check whether the SMB server policy recently changed
Ask the server administrator whether SMB signing requirements, domain policy, or the destination host changed around the time the failure began.
Verify the printer is reaching the intended server
Confirm the saved host name/IP and share point lead to the expected Windows server or NAS rather than an old or redirected target.
Correct the signing/interoperability issue without disabling protections broadly
Use a server/printer configuration supported by both sides. Avoid globally disabling SMB signing or weakening unrelated security settings just to clear the code.
After each corrective action
Retry the same operation that produced 16711701. If it now works, stop there rather than changing unrelated printer, network, supply, or service settings.
If the code returns
If 16711701 returns on the intended server, have the administrator compare SMB signing negotiation from a working client with the printer's session and review any recent server-policy changes.
When service may be needed
This is normally an SMB security-negotiation issue. Escalate to the server/network administrator or Konica Minolta support if both endpoints are correctly configured; printer disassembly is not indicated.
Continue with guided troubleshooting
If the printer still is not working after the reviewed checks, carry this verified error context into the guided troubleshooter.
