Hi MB07,

46.* error messages

Errors in the 46.* family occur when the printer is trying to perform an action that it is not able to complete.

• No network connectivity
• A problem with the file being printed, with the software application sending the job, or with the print driver

Recommended action

Use the following general troubleshooting steps to try to resolve the problem. If the error persists, elevate the case using the Standard Support Process.

1. Turn the printer off, and then on.
2. Verify the printer is connected to the network. If it is not, use a different network cable, and check the configuration settings.
3. Send a different file from the same software application to see if the error is specific to the original file. Try sending a job from a different software application to see if the error is specific to the application. Verify the computer has the correct print driver installed.
4. Upgrade the printer firmware.

Also try printing internal pages  like a config, usage or supplies page.

I hope this might help,

Cheers!
