Diagnostic Decision Tree: Canon imageCLASS Scan to Email Setup Guide: SMTP, Gmail & Remote UI

Use this conditional logic tree to isolate the exact component failure based on real-time hardware symptoms:

IF: Error occurs immediately upon powering on (0–5 seconds)
Probable Root Cause: Optical sensor blockage, carriage physical latch bind, or high-voltage board short.
Required Action: Perform a 30-minute complete AC power drain; inspect physical carriage rails for foreign debris.
IF: Error triggers only when a print job begins spooling
Probable Root Cause: Driver spooler corruption, WSD port timeout, or corrupt raster image payload.
Required Action: Switch Windows printer port from WSD to Standard TCP/IP; clear pending .SPL files in spool folder.
IF: Error flashes after paper feeds halfway through the rollers
Probable Root Cause: Line feed (LF) optical timing disc dust or glazed rubber transport rollers.
Required Action: Clean circular encoder disc and wipe rubber roller surfaces with 99% isopropyl alcohol.

Understanding Canon imageCLASS Scan to Email

Canon imageCLASS multi-function laser printers can dispatch scanned PDF documents directly to recipient email addresses without a computer.

Because the printer acts as its own email client, you must configure SMTP server credentials, SSL/TLS encryption, and authentication tokens via the Canon Remote UI web portal.

Step 1: Access the Canon Remote UI Web Portal

Log into your printer's embedded web server using a computer on the same local network:

  1. Find your printer's IP address: On the imageCLASS touchscreen, tap Status Monitor > Network Information > IPv4.
  2. Open Remote UI in your browser: Type http://<printer-ip> into Chrome, Firefox, or Safari.
  3. Log in as System Manager: Select System Manager Mode. The factory default System Manager ID and PIN are both 7654321.
  4. Navigate to Email Settings: Click Settings/Registration > Network Settings > E-Mail/I-Fax Settings.

Step 2: Configure SMTP Server and Gmail App Passwords

Standard email passwords are rejected by Gmail and Microsoft due to mandatory multi-factor authentication (MFA):

  1. Generate an App Password: For Gmail, go to Google Account Security > 2-Step Verification > App Passwords. Generate a 16-character token for "Canon Printer".
  2. Enter SMTP Server Name: Type smtp.gmail.com (or smtp.office365.com for Microsoft 365).
  3. Set the SMTP Port: Enter 587 (with STARTTLS) or 465 (with SSL/TLS).
  4. Enable SMTP Authentication: Check Use SMTP Authentication (SMTP AUTH). Enter your full email address and the 16-character App Password.
  5. Set Default Sender Address: Enter your full email in the E-Mail Address box so receiving servers do not flag scans as spam.

Step 3: Configure DNS and Gateway Addresses

The printer must resolve domain names over the internet to connect to Google's mail servers:

  1. Open TCP/IP Settings: In Remote UI, go to Network Settings > TCP/IP Settings > DNS Settings.
  2. Set Primary DNS Server: Enter 8.8.8.8 (Google Public DNS) or 1.1.1.1 (Cloudflare).
  3. Set Secondary DNS Server: Enter 8.8.4.4.
  4. Reboot the printer: Click OK and power cycle the printer so the new network routes take effect.

Frequently Asked Questions

Why do I get error #801 or #806 during scan to email?

Error #801 indicates incorrect SMTP authentication credentials. Error #806 indicates the recipient email address is blocked by the destination server or typed incorrectly.

Can I save frequent email recipients directly on the printer?

Yes. Go to Address Book in Remote UI or on the touchscreen to register one-touch speed dial buttons for frequent email contacts.

What causes error #753 when scanning to email?

Error #753 indicates the printer cannot reach the SMTP server. Verify your primary DNS address is set to 8.8.8.8 and your gateway IP address is correct.
