Scan to FTP: Setting Up Network Scanning to a File Server

What is scan to FTP?

Scan to FTP is a networking feature on many multifunction printers and all-in-one devices. When you select the FTP destination from the printer control panel, the printer converts your document into a digital file, usually PDF or JPEG, and uploads it to a folder on a server that runs an FTP service. That server can be a network-attached storage (NAS) device, a desktop with FTP software, or a dedicated business server.

Unlike printing, which uses protocols such as IPP Everywhere to connect clients and devices, scanning to FTP uses the standard File Transfer Protocol. This protocol is supported by most operating systems and NAS solutions, so you do not need to install special drivers on every computer. The printer communicates directly with the server over your local network, which means your scans are stored on the machine that also hosts the shared folder, not on a third party service. For a deeper look at how network protocols work, see our printer network protocols guide.

Why FTP beats email and USB for many scans

Email scanning sends your document as an attachment to an address you type on the printer's screen. That works when you scan occasionally, but it has limitations. Most email services cap the size of attachments, so high-resolution scans of many pages can fail or bounce back. You also need to know the exact recipient address, and the printer must be configured with outgoing mail server settings, which can be a hassle when your SMTP server changes. Compare this with scan to email and cloud methods.

USB scanning saves to a flash drive connected to the printer's USB host port. It is simple for a single user, but it keeps the scan at the printer itself. You have to walk to the printer, insert the drive, and later move the file to the right folder. In an office with several people, FTP lets you scan to a central repository that everyone can access from their own computers. There is no size limit from email, no physical storage to carry, and no need to remember an email address. If you want to know more about the USB approach, read our scan to USB guide.

How to configure FTP scanning on a network printer

The exact menu names vary by manufacturer, but the process follows a common pattern. You start with the FTP server details: an IP address or hostname, a user name and password if the server requires authentication, and the path to the destination folder. Some printers let you create multiple FTP profiles so you can scan to different folders without re-entering the information each time.

On the printer, go to the network or scan settings section, find the FTP or file transfer option, and create a new profile. Enter the server address, the target folder path, and credentials. Then test the profile by scanning a test page. If the job fails, check that the server is reachable from the printer and that the folder permissions allow the FTP user to write files. If you need help finding the server's IP address, see our guide to locating a printer IP address.

When to choose FTP over other scanning methods

Choose scan to FTP when you want scans to land directly in a shared folder that multiple users can access. This is common in offices that keep job files, receipts, or other documents in a network drive. It is also useful when you scan large documents, because there is no email attachment limit and no need to carry a flash drive. For a home office with one computer, email scanning may be simpler, but FTP becomes valuable once you have a NAS or always-on server.

Scanning to FTP is also an environmentally friendly choice when it replaces printing and filing, because you avoid paper waste. The EPA encourages reducing and reusing materials, and digital filing is part of that approach. If you are in the market for a printer that supports this workflow, our all-in-one printer guide and wireless printer guide list models that include network scan features.

Security and access control for FTP scanning

Because FTP transmits data over the network, you should consider the sensitivity of your documents. The standard FTP protocol sends credentials in clear text, so if your scans contain personal information, use FTPS (FTP over TLS) or SFTP if your printer and server support them. Keep the FTP server on a trusted segment of your network, and restrict folder permissions to the printer's user account and the people who need to read the scans.

The Printer Working Group, which defines many of the network protocols used by printers, also maintains standards for secure printing and scanning, but the security of your FTP setup ultimately depends on your own server configuration. Review your firewall rules and monitor the folder for unexpected files. For more on protecting your printer, see our printer security settings guide.

Troubleshooting common scan to FTP issues

If the scan to FTP feature fails, start with the basics. Test the connection from the printer to the server by pinging the server's IP address. Confirm that the FTP service is running and that the folder path is correct. Check the printer's error log for messages like 'connection refused' or 'login incorrect.' Often the issue is a typo in the user name or password.

Firewalls can also block FTP. Standard FTP uses a control connection for commands and a separate data connection for the transfer. Ensure your firewall allows both. Some routers and security suites have proactive settings to allow passive FTP. If you are still stuck, revisit the network protocols guide to refresh your understanding of how these connections work.

Questions

Does scan to FTP require a computer to be always on?

No, the printer sends files directly to the FTP server. The server must be running, but no workstation needs to be on. That is an advantage over USB scanning, which needs someone to insert a drive at the printer.

Can I use scan to FTP with a cloud service?

Not directly. FTP is designed for traditional file servers. If you want scans to go to a cloud drive, you can use scan to email or scan to a network folder that syncs with a cloud service. Some printers also have dedicated cloud scan options.

Is FTP scanning secure?

Standard FTP sends credentials in clear text. Use FTPS or SFTP if available, and restrict folder permissions. For sensitive documents, consider scan to email with encryption or a direct network folder with encrypted SMB.

What file formats can I scan to FTP?

Most printers output PDF or JPEG. Some also offer TIFF. You can choose the format in the scan settings on the printer's control panel before sending the job.

How does FTP compare to a network folder (SMB) scan?

Both let you save scans to a shared location without email. SMB writes directly to a Windows or Samba share, while FTP uses its own protocol. The choice depends on what your server supports. Many NAS devices offer both, and your printer may support both as well.
