Authentication With The Destination Has Failed | Fixes

Seeing authentication with the destination has failed on a Ricoh copier stops work fast. Scan to folder jobs stall, scan to email never arrives, and the panel just shows that line and asks you to check settings. The good news is that this message almost always traces back to a few clear causes you can fix with steady checks.

This guide walks through what the message really means, how it links to Windows shares and email servers, and the exact settings you should review on both the Ricoh panel and your PC or mail service. You do not need deep admin skills, but you do need access to the device settings and the computer or mailbox used for scanning.

You’ll start with quick checks, then move into step based fixes for scan to folder and scan to email. At the end you’ll tidy up naming, credentials, and passwords so this error stays rare instead of popping up every few weeks.

Authentication With The Destination Has Failed Error Meaning

On Ricoh multifunction devices the message appears when the machine can talk to the network but fails the login step at the final target. That target might be a Windows shared folder, a NAS share, an FTP server, or an SMTP server that sends the scan out as email. The device tries the stored username and password, the remote system rejects them, and the Ricoh shows this line.

In other words, authentication with the destination has failed means the network path works well enough to reach the host, yet the credentials or access rights do not match what that host expects. The wording can look like a network fault, but most of the time you’re dealing with a login problem, not a cable or switch problem.

The message can also appear when the path and credentials are fine, but the host demands a newer protocol or a different port. Common examples include older Ricoh models that still try to use SMB1 to reach a modern Windows share, or a scan to email setup that still points at port 25 even though the mail service now needs TLS on port 587.

Authentication With Destination Error Fixes For Ricoh Scanners

Before you dive into every menu, it helps to frame the main fix areas. Ricoh documents and admin threads line up on three broad categories: wrong or outdated credentials, wrong share or mailbox settings, and protocol mismatches between the device and the host. If you methodically cover those, you normally clear the message without a service call.

To keep your checks tidy, treat scan to folder and scan to email as two paths that just share the same pattern. Both need a host name or IP address, a path, a port, and a valid account. If any link in that chain changes on the PC side or mail side while the copier still holds the old value, you’ll hit the error during the next scan.

The table below sums up the most common patterns you’ll see on a Ricoh when this message shows up, along with the first place you should look for a fix.

Common Reasons Scan Authentication Fails On Ricoh Devices

On scan to folder jobs, the most frequent trigger is a simple account change. Someone updates their Windows password, or the shared account used for scanning gets a new password for policy reasons, yet the copier still holds the old one in its address book entry. The next time you scan, Windows rejects that old password and the Ricoh throws the message.

Hostname and path changes sit close behind. If you move a shared folder to a new server, rename the PC, or change the share name, the stored path on the copier points to a place that no longer matches reality. In some cases the machine can still reach the host IP but not the actual share path, which leads to the same message, since the device sees the host yet cannot complete the login at the folder level.

Protocol mismatches now come up more often, especially with older models. Many long running Ricoh devices were first set up back when SMB1 was standard on Windows. Modern Windows builds either disable SMB1 by default or phase it out later. If the device only speaks SMB1 and the host no longer accepts it, scan to folder jobs fail even if the username and password are still valid.

For scan to email, the root cause is often a growing set of mail security rules. Services such as Microsoft 365 expect SMTP authentication with TLS, stronger passwords, and in many cases app passwords when multi factor login is turned on. A Ricoh that still points at port 25 with no TLS or still uses a plain mailbox password will not pass that check, so the message on the panel hints that the remote host turned the job away.

Quick Checks Before You Change Scanner Settings

Before you rewrite every field on the device, run through a few quick checks from a nearby PC. These checks confirm that the host and the account work as expected. That way you know you’re repairing the copier entry instead of chasing a deeper network fault.

• Confirm the host name or IP — From a Windows PC on the same network, ping the server or PC that holds the folder or mail service to be sure it answers.
• Test the share with the same user — Log off and back on, then map the shared folder using the same username and password that should be stored on the copier.
• Check folder rights — On the folder’s properties, confirm that the scan account has both read and write rights on the share and on the NTFS tab.
• Send a test mail — From the mailbox you use for scan to email, sign in through web mail and send a message to be sure the account is active and not locked.
• Verify ports and TLS on the mail host — Note which SMTP host name and port your mail provider lists, and whether it expects TLS on 587 or SSL on 465.

If any of those tests fail on the PC, fix that issue first. There is no point editing the address book on the Ricoh while the target folder, account, or mailbox is broken even for a direct login. Once these basics pass, you can move on to device side adjustments with more confidence.

Step By Step Fixes For Scan To Folder Failures

When scan to folder fails with this message, the path, account, and protocol all deserve a close look. The steps below assume you have admin level access to the Ricoh web configuration page or front panel. Screens differ by model, yet the labels stay close enough that you can match them.

• Open the address book entry — In the web page or on the panel, find the programmed destination and open its details so you can see the path and credentials.
• Review the folder path syntax — Check the host field and path field; for Windows shares this often looks like \\SERVER\Share\Subfolder, while some models split server and path.
• Re enter the username — Type the account in the same format that works on a PC, such as DOMAIN\user or user@domain.tld, and avoid extra spaces.
• Re enter the password — Type the new password slowly, paying attention to case, numbers, and symbols; many devices hide the characters, so double check length as well.
• Run the built in connection test — Many Ricoh models offer a test button near the destination settings; use it to confirm that the device can now reach the folder.

If the error appears right after a Windows update or server change, pay attention to SMB settings. Some older devices only talk SMB1 and fail once the server disables it. You can turn SMB1 back on in Windows features for short term relief, yet that protocol is dated and better kept off where possible. A stronger path is to apply the latest firmware for the copier, then try SMB2 or SMB3 options if the model adds them.

For desktops that act as scan targets, watch for third party firewalls or security suites that block unknown SMB connections. When you see the message only on certain PCs, yet server based shares still work, that pattern often points to a local filter. You can often fix it by adding the device IP as an allowed host in the firewall rules so the scan traffic passes without complaint.

Scan To Email Fixes With Microsoft 365 Or Other Smtp

When scan to email fails with the same message, the copier usually reaches the SMTP host but does not pass the login rules. Modern mail platforms are strict about TLS and device logins, so every field on the SMTP screen matters. A small typo in the host name or a wrong port is enough to break the process.

• Confirm the SMTP host and port — Set the host to the exact name your provider lists, such as smtp.office365.com, and use the recommended port, most often 587 with TLS.
• Pick the right encryption mode — Choose the TLS or SSL option that matches the port; starting TLS on 587 and full SSL on 465 are the two common pairs.
• Use a mailbox that allows SMTP auth — In many tenants you must turn on SMTP auth for the mailbox that the Ricoh uses, or the service will refuse the login every time.
• Create and use an app password when needed — If the mailbox uses multi factor login, plain passwords seldom work; create an app password and store that on the device instead.
• Match the from address to the mailbox — Set the sender field on the Ricoh to the same address as the account used for SMTP auth to avoid policy rejections.

If you run through those steps and the copier still shows the message, check tenant level mail rules. Some setups only allow SMTP relay from fixed public IP ranges. In that case the fix is not on the device at all; your network team needs to list the public IP that the office uses so the mail host accepts traffic from that source.

On smaller mail hosts, watch out for rate limits and lockouts. Several failed login attempts from the same IP can push the mail host to lock the mailbox for a short period. Waiting a few minutes, resetting the password, and then entering the fresh password only once on the device can break that loop.

How To Prevent Future Destination Authentication Errors

Once the device is working again, a few housekeeping habits help keep this message from returning. These habits are simple yet they stop many repeat calls, especially after staff changes or password policy changes.

• Use a service account for scanning — Create a dedicated account just for scan jobs so password changes are rare and not tied to one person leaving the company.
• Store settings in one admin record — Keep a short document that lists each Ricoh, its scan accounts, and target paths so changes on servers or mail hosts are easier to align.
• Review firmware and features during upgrades — When you update servers or move to services such as Microsoft 365, plan a quick review of SMB and SMTP settings on each device.
• Limit how many hosts handle scan jobs — Where you can, point scan to folder at a central file server instead of many desktops so changes are easier to manage.
• Test after every password or path change — When you move a share or adjust a mailbox, send a short test scan right away so you can catch problems while the change is still fresh in mind.

With that small amount of planning, the next time someone sees authentication with the destination has failed you already know where to look. Rather than treating the message as a mystery, you can walk through credentials, paths, and ports in a calm order and get scans moving again with a few focused edits.
