Hardware Error: Main PCA Fan Malfunction

This error indicates a problem with the cooling fan on the Main PCA. Overheating could occur, leading to performance issues or damage.

• 1Dust and debris accumulation on the Main PCA fan blades, restricting movement or causing motor strain.
• 2Worn-out or failed Main PCA fan motor bearings, leading to reduced fan speed or complete seizure.
• 3Faulty fan control circuit on the Main PCA, failing to supply proper voltage or control signals to the fan.
• 4Loose or damaged fan power/signal cable connection to the Main PCA.
• 5Physical obstruction preventing the fan from spinning freely (e.g., dislodged internal component).

• Printer displays error code 55:03 on the front panel.
• Increased internal printer temperature, potentially leading to other thermal-related errors (e.g., printhead overheating).
• Unusual fan noise (grinding, whining, or no sound at all from the fan area).
• Intermittent or complete printer shutdowns due to overheating protection.
• Reduced printing performance or print quality degradation as components struggle under thermal stress.
