how do i get alexa to tell me when my canon pixma tr8620a is low on ink? i set it up but it's not talking to me.

Diagnosis

The failure of the Canon PIXMA TR8620a to push ink notifications to Alexa is typically not a hardware failure, but a "handshake" break between the Canon Cloud and the Amazon Alexa Skill. For Alexa to announce ink levels, the printer must not only be on Wi-Fi but must be registered to a Canon account via the Canon PRINT Inkjet/SELPHY app and linked to the cloud. If the printer is connected to Wi-Fi but "silent," the cloud-to-cloud communication is severed, meaning the printer is reporting low ink to the local network, but that data isn't reaching the Amazon servers. To confirm the root cause, check the printer's LCD screen. If you see a "Low Ink" warning on the machine itself but Alexa remains silent, the issue is a synchronization error within the Canon Skill permissions. Furthermore, if the printer is connected to a 5GHz band while your Alexa device is on 2.4GHz, some router configurations prevent the necessary API calls from triggering the "push" notification required for proactive voice alerts.

How to Fix It

Follow these exact steps to re-establish the communication link and enable proactive notifications:

1. Open the Canon PRINT Inkjet/SELPHY app on your mobile device. Ensure you are logged into your Canon account. Navigate to the printer settings and verify that "Cloud Printing" or "Remote UI" is enabled.
2. Open the Amazon Alexa App. Tap the "More" icon in the bottom right and select Skills & Games.
3. Search for the "Canon" skill. If it is already enabled, disable it first to clear the cache, then re-enable it.
4. When prompted, log in using the exact same credentials used for the Canon PRINT app. This is the most common point of failure; mismatched accounts will prevent ink data from syncing.
5. Once the account is linked, go to Devices > Printers and ensure the TR8620a is listed as "Online."
6. Navigate to the Settings menu within the Alexa app, select Notifications, and ensure that "Alerts" for the Canon Skill are toggled to "On."
7. Perform a test: If your ink is currently low, ask Alexa, "Alexa, ask Canon for my ink levels." If she answers correctly now, the proactive alerts are activated.

If That Didn't Work

• Reset the Network Stack: On the TR8620a operation panel, go to Settings > Device Settings > LAN Settings > Reset LAN Settings. Reconnect the printer to your Wi-Fi. This forces the printer to request a new IP address and refresh its registration with the Canon Cloud servers.
• Check the "Do Not Disturb" Mode: Ensure your Echo device is not in "Do Not Disturb" mode. If this is active, Alexa will receive the low ink notification from the Canon server but will not announce it verbally or light up the ring.
• Verify Ink Cartridge Chip Integrity: If you are using third-party or refilled cartridges, the TR8620a may not be able to read the ink level accurately. If the printer screen shows "Ink level unknown," the cloud server receives no data, and Alexa will have nothing to report. Replace with genuine Canon CLI-285/286 cartridges to test.
• Update Printer Firmware: Navigate to the printer's maintenance menu and select "Firmware Update." Outdated firmware on the TR8620a often contains bugs that cause the cloud link to time out every 24-48 hours.

Heads Up

• Genuine Ink Only: Alexa notifications rely on the chip on the cartridge. Non-Canon cartridges often bypass these sensors, rendering voice alerts useless.
• Power Management: Avoid using a power strip that completely cuts power to the printer. If the printer is fully powered down (rather than in Sleep mode), it cannot send the "Low Ink" trigger to the cloud.
• 2.4GHz Stability: For the most reliable connection, ensure your router's 2.4GHz and 5GHz bands have different names (SSIDs) and connect the TR8620a specifically to the 2.4GHz band.
• App Sync: Periodically open the Canon PRINT app once a week; this "wakes up" the account link and prevents the Alexa skill from timing out due to inactivity.
