Background
What this message usually means
Canon uses support code B203 for a repair-required error on the TS5000 series. This is not a user-maintenance warning. Canon's official guidance is to turn the printer off, unplug it, and request repair support rather than continuing normal troubleshooting.
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 printer detected an internal fault that requires repair.
A printhead or main print-system problem escalated into a service-stop error.
The device could not recover from a prior hardware fault during startup or use.
Service
When service or replacement is more likely
- -B203 is a stronger stop-and-escalate code than routine feed or cartridge warnings.
- -If the printer is older, it is worth weighing repair cost against replacement value.
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.
- -Assuming any supply-related wording means the next step is automatically to buy a cartridge, toner, drum, or printhead.
