Kyocera ECOSYS P3145dn error C-3300: Fan Fault

The Kyocera ECOSYS P3145dn error C-3300 signals a fault in the device's cooling system. Specifically, the fan rotation sensor detects that it is not reaching the nominal speed, which puts the equipment at risk of critical overheating. It is necessary to clear the ventilation area and, in many cases, remove accumulated dust that blocks the fan motor blades.
