- Check the Copper Contacts: Look at the gold strips on the side of the print head. Are they corroded, burnt, or have black spots? If yes, it is dead.
- Check the Nozzles: If it’s already in your printer, run a "Nozzle Check" from the maintenance tab. Missing lines or no ink at all indicates a clogged or burnt head.

- Firmware mismatches: Deploying an incorrect build (or failing to update) can cause job failures, missing features, or incompatibilities with print drivers and network authentication.
- Limited documentation: Service identifiers like FU78783 are often poorly documented publicly, making troubleshooting by end users difficult without Canon support.
- Update process: Firmware/service updates can require downtime and sometimes a technician-level reset; incomplete updates can brick devices or require enterprise support intervention.
