Background
What this message usually means
Canon uses support code 15A1 when the TR4500 series has not completed part of its initial setup state, such as selecting language or country/region. This is a setup-state issue rather than a print hardware fault.
Before the message
What users usually notice first
Messages like this often appear after the printer fails one of its normal startup, supply, or paper-path checks and cannot return to ready state cleanly.
Diagnosis
Likely causes
The first-time setup flow was interrupted before language or region was saved.
The printer was powered on after reset without finishing regional setup.
A setup-state check is blocking normal use until configuration is complete.
Service
When service or replacement is more likely
- -Treat this as a setup blocker, not as a service-stop printer fault.
Avoid wrong turns
Common misreads of this message
- -Treating the message like a confirmed failed part instead of a support clue about which system has stopped the printer.
