# Sharp Copier Scan-to-Email Stopped Working with Gmail? Here's the Fix

A step-by-step guide to getting Scan to Email working again after Google's security changes

If your scan-to-email suddenly stopped working and you're sending to a Gmail address, you're not imagining things. Google changed their security rules a while back and now requires two extra things before any device like a copier can send email through Gmail: **2-Step Verification** turned on, and an **App Password** generated for the copier to use instead of your regular Gmail password.

The good news: the fix is pretty mechanical once you know the steps. Here it is end to end.

## Part 1: Turn on 2-Step Verification in your Gmail account

Sign in to the Gmail account that the copier uses to send scans, then click your profile photo and choose **Manage your Google Account**. From the left menu, pick **Security**.

 The Security section of your Google Account is where all of this lives.

Scroll down to the section called **Signing in to Google**. You'll see entries for Password, 2-Step Verification, and App passwords. Click **2-Step Verification** and follow the prompts.

 You need 2-Step Verification turned on before App Passwords becomes available.

Google will ask you to enter your Gmail password and provide a cell phone number. They'll text you a 6-digit verification code to confirm. Enter it, and 2-Step Verification is now active.

## Part 2: Generate an App Password for the copier

Now that 2-Step Verification is on, go back to the Security page and click **App passwords**. Use the dropdowns to select **Mail** for the app, then **Other (Custom name)** for the device. Type something like *Scan to Email* as the name.

 Pick Mail as the app and Other as the device — name it something like "Scan to Email."

Click **Generate**. Google will display a **16-digit password**. **Write this down or copy it somewhere safe right now** — you'll need to paste it into the copier in the next step, and Google won't show it to you again.

## Part 3: Find your copier's IP address

Open the Windows search bar and type "printers." Click **Printers & scanners** in the results.

 Windows search for "printers" gets you to the printer settings quickly.

Find your Sharp copier in the list, click it, choose **Manage**, and then **Printer properties**. Click the **Ports** tab and look for the checked port — that's the IP address you need.

 The checked port is your copier — note the IP address.

## Part 4: Update the password in the copier

Open Chrome or your preferred browser and type the copier's IP address into the address bar. Press Enter.

 Just type the IP — no https, no www.

You should see the Sharp web interface load up.

 This is the same web interface you use for everything else on the copier.

Click the **System Settings** tab at the top, then click **Network Settings**.

 Network Settings is in the right column.

The Sharp will ask you to log in. The default Login Name is **Administrator** and the default Password is **admin** (all lower case). Click **Login**.

 Default admin password is "admin" — all lower case.

In the left menu, click **Quick Settings**, then scroll down to the **SMTP Authentication** section.

 SMTP Authentication is where you tell the copier how to log in to Gmail.

Confirm the **User Name** matches the Gmail address you've been using for scans. Then check the **Change Password** box and paste in the **16-digit App Password** you generated earlier. Click **Submit** at the bottom of the page to save.

**Important:** Paste the App Password without any spaces. Google displays it with spaces between every four digits for readability, but those spaces aren't part of the password.

## Part 5: Test the connection

While you're still on this page, find the **Connection Test** section and click the **Execute** button.

 Run a connection test before you walk away.

A confirmation popup will appear listing your DNS servers (typically `8.8.8.8` and `8.8.4.4`) and the domain name. Click **OK** to perform the test.

 The test popup confirming your DNS settings before running.

If everything's right, you'll see **"Connection to SMTP server test succeeded"** at the top of the page.

 Success looks like this. Don't forget to click Submit one more time.

Click **Submit** one last time to save everything. Let the copier reboot if it asks, then walk over and try scanning a document to email. It should land in your inbox within a minute or two.

## If the test fails

The most common cause is a typo in the 16-digit password. Try entering it again — slowly, no spaces — and re-run the connection test. If it's still failing after a clean re-entry, double-check that the User Name field exactly matches the Gmail address you generated the App Password from.

**Going forward:** the App Password is tied to that specific Gmail account and device label. If you ever change Gmail accounts or want to revoke a copier's access, you can do it from the same App Passwords screen in your Google Account — just delete the one named "Scan to Email" and the copier will stop being able to send.
