How to Scan to Email Directly From Your Scanner

If you've ever wanted to skip the extra steps of scanning a document, saving it to your computer, and then attaching it to an email, you're not alone. Learning how to scan to email from scanner directly can save you several minutes on every document you send — and once it's set up, the process becomes almost effortless. Whether you're working from a home office or a small business environment, this guide walks you through everything you need to know to get scan-to-email working reliably on your device.

The scan-to-email feature is built into most modern multifunction printers and network scanners. It lets the scanner send a scanned document directly to one or more email addresses without ever touching your computer. You simply place the document, enter or select a destination email, and press send. For more details on how this compares to other sharing options, see our guide on scan to cloud vs scan to email.

What You Need Before You Start

Before you configure anything, it helps to gather a few key pieces of information. Setting up scan-to-email is not difficult, but the process does require some technical details that many users overlook — and missing even one of them can cause the feature to fail silently.

A Compatible Scanner or MFP

Not all scanners support scan-to-email natively. Flatbed-only scanners connected via USB typically do not have this feature — they rely entirely on the host computer. Scan-to-email is most commonly found on:

• Networked multifunction printers (laser or inkjet) from Brother, HP, Canon, Epson, and Xerox
• Dedicated document scanners with Ethernet or Wi-Fi connectivity
• Office-grade MFPs with a touchscreen control panel

If you're unsure whether your model supports the feature, check the manual or the manufacturer's product page. You might also want to read our comparison of document scanner vs multifunction printer to understand which type of device suits your workflow best.

Your SMTP Server Details

The scanner sends email using SMTP (Simple Mail Transfer Protocol), the same protocol email clients use to send messages. You'll need the following before you begin:

• SMTP server address (e.g., smtp.gmail.com)
• SMTP port (usually 587 for TLS or 465 for SSL)
• Your email address (this becomes the "From" address)
• Your email password or app-specific password
• Authentication method (SSL or STARTTLS)

For Gmail and other modern email providers, you'll need to generate an app password or enable less-secure app access — more on that in the SMTP settings section below.

How to Set Up Scan to Email on Your Scanner

The exact menu names vary by brand, but the process is broadly the same across most devices. You access the scanner's built-in web server, configure the outgoing mail settings, and optionally save email addresses to an address book for quick access later.

Access the Scanner's Web Interface

Most networked scanners run a small web server accessible from any browser on the same network. Here's how to reach it:

1. Make sure your scanner is connected to the same Wi-Fi or wired network as your computer.
2. Print a network configuration page from the scanner's menu — this shows the device's IP address.
3. Type that IP address into your browser's address bar (e.g., http://192.168.1.45).
4. Log in with the admin password (often "admin" or blank by default — change this after setup).

On some Brother and HP models, you can also access settings directly through the scanner's touchscreen under Settings → Network → Scan to Email or a similarly named menu.

Configure SMTP Settings

Once inside the admin interface, look for a section called Scan to Email, Email Setup, or SMTP Configuration. Enter the details for your email provider. The fields are typically:

• SMTP Server: The outgoing mail server address
• Port: 587 (STARTTLS) is the most widely supported
• Sender Email Address: The address your scans will appear to come from
• Authentication: Enable this and enter your credentials
• Encryption: Choose SSL/TLS or STARTTLS depending on your provider

After entering your settings, use the Test Email or Send Test button if your scanner provides one. A test email to your inbox confirms everything is working before you commit to the configuration.

Add Email Contacts or Address Book

Most MFPs let you store email addresses in an on-device address book so you don't have to type them manually each time. In the admin web interface, find the Address Book or Contacts section and add entries with a name and email address. On the control panel, these then appear as one-tap destinations.

SMTP Settings for Common Email Providers

These are the settings you'll need for the most popular email services. If your provider isn't listed, search for "[provider name] SMTP settings" — most publish this information in their help documentation.

Gmail note: Google requires you to use an App Password rather than your regular account password when authenticating third-party devices. Go to your Google Account → Security → Two-Step Verification → App Passwords, and generate a 16-character password specifically for your scanner. Enter that in the scanner's SMTP password field.

How to Scan and Send a Document by Email

Once your SMTP settings are saved and tested, the day-to-day process of scanning to email is fast. Here's what it looks like in practice.

Sending from the Control Panel

1. Place your document face-down on the glass or face-up in the ADF (automatic document feeder).
2. On the control panel, tap or navigate to Scan → Scan to Email.
3. Select a recipient from your address book, or manually enter an email address.
4. Adjust scan settings if needed (resolution, color, file format).
5. Press Start or Send.

The scanner processes the document, converts it to the chosen file format, and sends it through your configured SMTP server. The recipient gets a standard email with the scanned file attached — typically as a PDF or JPEG.

If you're frequently scanning multi-page documents, you'll want a scanner with an ADF. For context on how those work, see our article on what is an ADF scanner and do you need one.

Choosing the Right File Format

Most scanners offer at least PDF and JPEG output for scan-to-email. Here's a quick guide to which format to use:

• PDF: Best for documents, contracts, forms, and multi-page files. Preserves layout and is universally readable.
• JPEG: Good for photos or single-page documents where small file size matters more than perfect fidelity.
• TIFF: High quality but large file size — rarely needed for email.
• Searchable PDF: Some scanners support OCR at the device level, producing PDFs with embedded, selectable text. Extremely useful for archiving documents.

For scanners that don't support on-device OCR, you can still create searchable PDFs after the fact. Read our guide on how to use OCR with your scanner to create searchable PDFs for step-by-step instructions.

Troubleshooting Scan-to-Email Problems

Scan-to-email is one of those features that works flawlessly once properly configured — but getting there can involve a few frustrating false starts. These are the most common issues and how to fix them.

Authentication Errors

An authentication failure usually means the scanner's login credentials were rejected by the mail server. This is the most common scan-to-email problem, especially with Gmail and Yahoo.

• Wrong password: If you recently changed your email password, update it in the scanner's SMTP settings too.
• App password not used: Gmail and Yahoo require app passwords for third-party devices with two-factor authentication enabled. Your regular password will not work.
• Two-factor authentication: Even if you don't think you have 2FA enabled, some accounts enforce it by default. Check your account security settings.
• SMTP authentication disabled: Some business Office 365 tenants have SMTP AUTH disabled by default. An IT admin will need to enable it for your account.

Connection Failures

If the scanner can't even reach the mail server, the problem is usually network-related rather than credential-related.

• Wrong port or encryption: Double-check the port and SSL/STARTTLS setting against the table above. Mismatched encryption types cause silent connection failures.
• Firewall blocking outbound SMTP: Some networks block ports 465 or 587 outbound. Try port 25, or ask your network administrator to open the relevant port.
• Scanner not on the network: Verify the scanner has a valid IP address. Print a network status page from the scanner menu to check.
• DNS resolution failure: If the scanner can't resolve smtp.gmail.com, try entering the scanner's DNS server manually (8.8.8.8 works as a fallback for testing).

Tips for Getting the Best Results

With scan-to-email set up and working, here are a few practices that will improve your results and keep things running smoothly over time.

Set a sensible default resolution. For text documents, 200–300 DPI produces clean, readable scans without bloating the file size. Higher resolutions are rarely needed for emailed documents and can cause attachments to exceed email size limits. For a deeper look at how resolution affects different use cases, see our guide on what scanning resolution do you actually need.

Keep your firmware updated. Scanner manufacturers occasionally release firmware updates that fix scan-to-email compatibility issues with email providers, especially after those providers update their security requirements. Check your manufacturer's website periodically or enable automatic updates if your device supports it.

Use a dedicated email account. If multiple people in an office will be using the same scanner, consider setting up a shared mailbox or a dedicated scanner email address (e.g., scanner@yourdomain.com). This keeps the "From" address consistent and avoids credential issues when individual employee passwords change.

Test after any password change. Email password updates are the number one reason scan-to-email stops working unexpectedly. After any account password change, immediately update the scanner's SMTP settings and run a test send.

Protect your SMTP credentials. Change the scanner's admin password from the default and restrict access to the web interface to trusted network IPs where possible. If the scanner's admin panel is left open with default credentials, anyone on the network could access or modify your email settings.

Consider file size limits. Most email providers cap attachments at 10–25 MB. High-resolution scans of multi-page documents can easily exceed this. Use PDF compression settings (available on most MFPs) or scan at a lower resolution for long documents.
