Background
What this message usually means
Canon uses support code 15A2 when the TS3300 series detects that a required FINE cartridge is missing. This is a setup or cartridge-installation issue rather than a deeper printer-mechanics problem.
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
A required FINE cartridge was removed and not reinstalled.
Initial setup or cartridge replacement was left incomplete.
The printer cannot detect one of the required cartridges at all.
Service
When service or replacement is more likely
- -Treat this as a missing-cartridge state, not as a service-stop error.
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.
