Error Status

When an error occurs, the printer stops printing, goes offline, and the Error LED flashes.
There are three error types: automatically recoverable errors, recoverable errors, and unrecoverable errors.

Automatically Recoverable Errors

Printing is temporarily suspended when automatically recoverable errors occur. They can recover automatically,
as described below.
