Epson 322 on inkjet printer: folder authentication error
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
Code 322 in Job Status on your Epson EcoTank means 'An authentication error has occurred' when scanning to a network folder: check Location, User Name, and Password, confirm the password is not expired, and verify Sharing and Security permissions.
Safety first
Stop and check this first
- Never include your account password in screenshots or support emails; record only the shared folder Location path and User Name.
Safe checks you can perform
- Check Location, User Name, and Password on the printer
- Confirm on the computer that the password is valid and not expired
- Verify 'allowed' permissions on the Sharing and Security tabs

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 for network folder authentication
What they doIf another device on the network can log on and write to the shared folder using the exact same SMB credentials while the printer still fails with code 322, contact Epson support.
They must show youa test scan saved to the network folder with no 322 error in Job Status.
In writingthe network configuration or firmware checked and the Epson case number.
Network or file-server administrator
What they doIf the shared folder sits on a domain or office server and code 322 persists with valid credentials, have your network administrator check the SMB authentication method and server permissions.
They must show youverified write access to the shared folder using the printer's assigned user account.
In writingthe required user name format, folder permissions applied, and IT ticket number.

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.
Check Location, User Name, and Password on the printer
- Who:
- you, from the control panel or Web Config.
- How:
- under Scan > Network Folder, open Keyboard > Edit Location (or inspect the saved Contact) and check Communication Mode, Location (Required), User Name, and Password.
- Result that matters:
- confirming that the folder path and login credentials match the target computer.
- If the user name or password was mistyped:
- re-enter it and retry the scan.
- If the entries look right:
- check on the computer whether the account password expired.
- Evidence to keep:
- a photo or screenshot of Edit Location showing Communication Mode, Location, and User Name.

Confirm on the computer that the password is valid and not expired
- Who:
- you or the owner of the computer user account.
- How:
- sign in to the destination computer using the exact same User Name and Password to make sure the account is active and the password has not expired.
- Result that matters:
- verifying that the computer accepts the credentials configured on the printer.
- If the password had expired or changed:
- update it on the PC and in the printer's contact.
- If the account signs in normally:
- inspect the shared folder permissions.
- Evidence to keep:
- confirmation that the user account logs in cleanly on the target computer.

Verify 'allowed' permissions on the Sharing and Security tabs
- Who:
- you or an administrator on the destination computer.
- How:
- open the shared folder's properties on the computer, and on both the Sharing tab and the Security tab add access rights for the user in the contacts list and set the permissions to 'allowed'.
- Result that matters:
- giving the authenticated user account write access to save scans in the shared folder.
- If permissions were missing on Sharing or Security:
- setting both to 'allowed' resolves 322.
- If both tabs are set to 'allowed' and code 322 continues:
- contact your network administrator.
- Evidence to keep:
- screenshots of the Sharing tab and Security tab permissions for that user.

What it means
In Epson's User's Guide for the ET-5800, ET-5805, and L6550 series ('Error Code is Displayed on the Status Menu,' 'Messages are Displayed on the Control Panel,' and 'Destination Menu Options for Scanning to a Network Folder'), code 322 appears in Job/Status > Job Status with the message 'An authentication error has occurred' when logging on to the destination computer fails. Other models may differ, and the code alone never proves a hardware part is faulty.
