Background
What this message usually means
Canon uses support code 5B00 for a printer error on the TS3300 series that Canon routes to service. This is a stronger stop-and-escalate fault rather than a normal user maintenance warning.
Diagnosis
Likely causes
The printer detected an internal maintenance or service-stop condition.
A deeper internal fault blocked normal operation.
The device cannot recover from its current error state through normal user steps.
Service
When service or replacement is more likely
