Background
What this message usually means
Canon uses support code 1403 when the TS5000 series believes the printhead may be damaged. Unlike a simple reseat warning, Canon's official guidance points straight toward repair support, so this should be treated as a serious printhead fault rather than a routine cartridge issue.
Diagnosis
Likely causes
The printhead has developed an internal electrical fault.
The printer cannot complete its printhead self-checks.
A prior printhead or carriage issue has progressed to a hardware fault.
Service
When service or replacement is more likely
- -This is more serious than a missing-ink-tank or install-position warning.
- -Repeated cleaning cycles are not a realistic fix for a persistent 1403.
