Epson 313 on inkjet printer: scan to email communication error
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
Code 313 in Job Status on your Epson EcoTank means a communication error occurred while sending a scan by email. Print a network connection report, review the email server settings and run the connection check to find the cause.
Safety first
Stop and check this first
- Never share the email account password in screenshots or messages when asking for help; note only server, port and method.
- If the test reports an untrusted connection, check the printer's date and time or the CA certificate; Epson recommends keeping certificate validation enabled.
Safe checks you can perform
- Print the network connection report
- Run the mail server connection check
- Review authentication, port and encryption

What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Epson support
What they doIf the network works, the connection test succeeds and scan to email still fails with 313, contact Epson support or its authorised service.
They must show youthe network connection report and the mail connection test result.
In writingthe diagnosis, whether a firmware update is needed and the case number.
Network administrator or email provider
What they doIf the test points to a down SMTP server, a DNS error or mismatched encryption, whoever runs your network or mail service should supply the correct values.
They must show youthe server, port, authentication and encryption values the printer should use.
In writingthe recommended configuration and the ticket number if one is opened.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Print the network connection report
- Who:
- you, from the printer panel.
- How:
- print the network connection report Epson recommends and confirm the printer shows as connected over Wi-Fi or Ethernet before changing any email settings.
- Result that matters:
- knowing whether the fault is the wider network or only the mail server.
- If the report shows the printer offline:
- fix the network connection first.
- If the network is fine:
- move on to the mail server connection check.
- Evidence to keep:
- the printed network connection report with its date.

Run the mail server connection check
- Who:
- you or the printer administrator.
- How:
- on the panel go to Settings > General Settings > Network Settings > Advanced > Email Server > Connection Check, or in Web Config open the Network tab > Email Server > Connection Test and select Start.
- Result that matters:
- getting the specific test message (network, DNS, authentication or secure connection).
- If it reports Connection test was successful:
- retry the scan to email.
- If an error message appears:
- correct the setting it names using Epson's reference table.
- Evidence to keep:
- a photo or screenshot of the connection test result.

Review authentication, port and encryption
- Who:
- you, with the details from your email provider.
- How:
- in the mail server settings confirm authentication method, account and password, sender's email address, SMTP server address and port, and the Secure Connection type; if you choose Off, the server must not require authentication either.
- Result that matters:
- the printer settings matching what the server requires.
- If a value did not match:
- correct it and repeat the connection test.
- If everything matches and 313 continues:
- the server or the local network may be at fault.
- Evidence to keep:
- the server parameters written down, leaving out the password.

What it means
The ET-5800 series user's guide lists 313 among scan to email job codes and defines it as a communication error. Epson suggests printing a network connection report to confirm the printer is on the network, reviewing the email server settings and running the connection check to reveal the cause, and making sure the authentication method matches the server's. Other models may number it differently. The code points to the network or to the email setup rather than to a fault in the printer itself.

Symptoms and causes
Probable causes · in order
- Printer not connected to the networkCommon
Epson suggests a network connection report because one source of the communication error is simply that the printer is not on the network.
Evidence: Epson ET-5800 series: Error Code is Displayed on the Status Menu · Epson ET-5800 series: Mail Server Connection Test References
- Authentication method does not match the serverCommon
If the printer uses Off while the server expects authentication, or the reverse, Epson says communication fails; the two settings must agree.

- SMTP server down or link droppedPossible
The connection test references mention an SMTP server that is down, the network dropping mid communication or incomplete data being received.
Evidence: Epson ET-5800 series: Mail Server Connection Test References
- Wrong secure connection choicePossible
The test can ask you to change Secure Connection to None, SSL/TLS or STARTTLS when server and printer disagree on encryption.
