PIXMA TR8620 Scanner suddenly stopped working

Jertoons — Sun, 29 Mar 2026 14:14:06 GMT

I have a TR8620 printer connected to my Mac running Sequoia 15.5. I use the scanner function very frequently. Unfortunately the scanner no longer works. I downloaded the new IJ Scan Utility Lite driver, but it still doesn't work. The error box I receive is as follows:

Cannot communicate with scanner. Possible reasons:

- Scanner is turned off.

- (If using wired LAN connection) It is disconnected from wired LAN.

- (If using Wi-Fi connection) Signal strength is poor due to obstructions.

- (If using USB connection) USB cable is disconnected.

Please check and try again.

The printer is connected via WiFi. Signal is strong. Print function works fine with my desktop and iPhone. Any suggestions?

Hi Jertoons,

Please open Image Capture on your Mac.

Once open, please attempt to scan. Are you able to scan using Image Capture?

If not, what is the error code that appears?

Patrick,

I opened Image Capture and was able to successfully scan a doc. After that I went back to the IJScan Utility Lite and tried to scan a doc. Eureka, success. At this point it appears that my issue has been resolved. Thank you for your help and expertise.

Patrick,

I have to withdraw my Eureka. Last night I shut down my desktop and printer. This morning I started everything back up and to my dismay, the scanner no longer works. Image Capture does not even recognize the scanner. Desktop printing works fine. Printer is recognized by my iPhone. When I go into settings, I see the printer and when clicking on it the "open scanner" button is there, but clicking on it opens Image Capture and the scanner is still not found. Error messages from IJ Print Utility is as in the previous post. I hope you can help again.

Hi Jertoons,

Please perform the following steps to try and resolve this issue:

1. Please tap the Wi-Fi icon in the lower left corner of your PIXMA TR8620's display.

2. Next, select Wi-Fi.

3. Select the Advanced button at the bottom.

4. Select TCP/IP settings.

5. Select IPv6 and then Yes.

6. Select Enable/disable IPv6

7. Select Disable.

Once "Processing" goes away and Enable/disable IPv6 appears again, please turn your TR8620 off.

Next, please go to your router and unplug the power cord from the back of your router.

Wait 5 minutes and then reconnect the power cord to your router.

When your Wi-Fi network is back online, please turn your TR8620 back on and attempt to scan.

Everything that was discussed above, I have tried everything and I still can't scan to my laptop. But I am able to print to laptop. I even called Apple Support, Canon Support, they can't help me at all.
