Samsung Multifunction Printer Error Code #06-015

Error #06-015 indicates a problem with the toner concentration (T/C) sensor inside the imaging unit. This sensor monitors toner density during printing, and when it fails to communicate a valid signal, the printer stops operation and displays this code. The fault can stem from a loose harness connection, a damaged connector, a failed sensor, or a defective imaging unit.

A simple power cycle or reset is unlikely to permanently clear error #06-015 because it points to a hardware fault in the T/C sensor circuit. The error may disappear temporarily after a reset, but it will return if the underlying problem with the sensor or harness is not corrected. Addressing the root cause is necessary for a lasting fix.

Repair costs vary depending on the failed component. If the issue is only a loose or damaged harness, the cost may be minimal, primarily covering a service call or technician labor in the range of $50 to $150. Replacing the T/C sensor or imaging unit will add parts costs, which can range from $30 to $200 or more depending on the specific model. A main control board replacement would be the most expensive scenario, potentially reaching $150 to $400 or higher for parts and labor.

Start by powering off the printer and checking the T/C sensor harness connection for loose or damaged connectors. Reseat the harness firmly at both ends and inspect the pins for corrosion or bending. If the connection is secure and the error persists, the T/C sensor or imaging unit may need to be replaced. A qualified technician can perform continuity testing on the harness and sensor to confirm which component has failed.

It is not recommended to continue printing with this error active. The T/C sensor controls toner concentration, and operating without accurate feedback can result in poor print quality and potential damage to internal components. The printer typically halts automatically to prevent this, and the underlying fault should be resolved before resuming normal use.
