Samsung Multifunction Printer Error Code #02-000

The #02-000 error code signals a fuser system fault. It can mean the fuser failed to reach its target temperature within 20 seconds during warm-up, the ADC circuit received abnormal temperature sensor readings, or the ZeroCross signal from the power supply was not detected. The printer stops operation to protect against unsafe fuser conditions.

No, you should not attempt to continue printing while this error is active. The fuser operates at high temperatures, and if the temperature control or sensing circuit is compromised, there is a risk of overheating. The printer disables itself for this reason, and bypassing that protection is not recommended.

If the fuser unit is the cause, replacement fuser units for Samsung printers typically range from $30 to $120 depending on the model. If the SMPS or a control board is at fault, parts and labor can push repair costs into the $100 to $300 range. In some cases, particularly for older models, the cost of repair may approach the value of the printer itself.

Some users with mechanical comfort can replace the fuser unit themselves, as it is a user-serviceable component on many Samsung printer models. However, if the fault is traced to the SMPS, engine control board, or fuser control board, those repairs involve higher-voltage components and soldering, which are better handled by a qualified technician. Always disconnect power before opening the printer.

A power cycle may temporarily clear the error display, but the underlying fault will almost certainly cause the code to return once the printer attempts to warm up again. A reset does not repair a failed fuser, a faulty thermistor, or a defective SMPS. The root cause must be identified and corrected for the error to be resolved permanently.
