Epson Job Status Code 314
On the WorkForce Pro WF-C878R/WF-C879R job-status platform, code 314 identifies a scan to email / size condition. The job type matters because Epson reuses nearby numeric ranges for different scan and forwarding functions.
Error meaning
The scanned attachment exceeds the configured maximum size.
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 scanned file exceeds the printer's configured attachment maximum.
- Resolution, color mode, or a large page count created an oversized file.
- The mail system may also have a lower message-size limit.
What to try
Reduce the scan size
Try fewer pages or split the document.
Lower resolution or increase compression
Use settings that still preserve readable output.
Review the attachment maximum
If appropriate, an administrator can compare the device's Attached File Max Size with the mail service limit.
Retry the smaller job
Send the same destination a reduced file and confirm the size condition clears.
After each corrective action
Retry the same operation that produced 314. If it now works, stop there rather than changing unrelated printer, network, or service settings.
If the code returns
If a very small scan still returns 314, verify the profile and configured attachment limit rather than repeatedly changing unrelated network settings.
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.

If the printer still is not working after the reviewed checks, carry this verified error context into the guided troubleshooter.
