Samsung Multifunction Printer Error Code #06-013

Error #06-013 indicates a problem with the toner concentration (T/C) sensor in the imaging unit. This sensor monitors the toner-to-carrier ratio inside the developer section to regulate print density. When the sensor signal is absent or out of range, the printer stops and displays this code to prevent print quality issues or internal damage.

A simple power cycle or reset is unlikely to permanently clear this error because it is triggered by an active hardware fault in the T/C sensor circuit. The error will typically return if the underlying issue with the sensor, harness, or imaging unit has not been resolved. Resetting may be useful as a temporary step to confirm whether the fault is intermittent, but it is not a substitute for proper diagnosis.

If the fix is simply reseating a loose harness connector, there may be no parts cost involved, only labor time. Replacing a T/C sensor or wiring harness typically ranges from moderate to mid-level parts cost, generally between $20 and $80 depending on the model and supplier. If the imaging unit itself needs replacement, costs can range from $50 to $200 or more. Main board replacement represents the most expensive scenario, often ranging from $150 to $400 or higher.

Start by checking the T/C sensor harness connection, ensuring it is fully seated at both the sensor and control board ends. If the connection is secure, inspect the harness for physical damage and test for continuity. If the wiring is intact, the T/C sensor itself or the imaging unit may need to be replaced. In rare cases, the main control board is responsible.

The printer will generally halt operation when this error is active, which is intended to prevent poor output and protect internal components. You should not attempt to bypass the error and continue printing without addressing the root cause. Operating with a faulty T/C sensor can lead to inconsistent toner application and potential damage to the imaging unit or developer assembly.
