Epson Job Status Code 330
On the WorkForce Pro WF-C878R/WF-C879R job-status platform, code 330 identifies a secure destination / certificate condition. The job type matters because Epson reuses nearby numeric ranges for different scan and forwarding functions.
Error meaning
An FTPS/HTTPS secure-connection error occurred.
This meaning is tied to the reviewed family/platform and subsystem below; do not reuse the number by itself on a different printer family or protocol.

What usually causes it
- The secure destination cannot be trusted with the current certificate store.
- A root/CA certificate needed for FTPS/HTTPS is missing or outdated.
- The saved destination or secure protocol settings may be wrong.
What to try
Check the destination settings
Confirm the saved FTPS/HTTPS host and secure protocol are correct.
Review the certificate chain in Web Config
Update/import the required root or CA certificate using Epson's supported administration method.
Check the printer's date and time
An incorrect clock can make otherwise valid certificates fail.
Retry the original secure scan
Confirm the connection succeeds without disabling certificate validation.
After each corrective action
Retry the same operation that produced 330. If it now works, stop there rather than changing unrelated printer, network, or service settings.
If the code returns
If 330 returns, involve the network/security administrator to verify the destination certificate chain and trust configuration.
When service may be needed
The checks above stay at the user/admin configuration level. If the setting is controlled by an organization, use the administrator rather than bypassing security or certificate requirements.
Continue with guided troubleshooting
If the printer still is not working after the reviewed checks, carry this verified error context into the guided troubleshooter.
