What #10-002 means on a Samsung multifunction printer

Error code #10-002 on a Samsung multifunction printer indicates a fax unit communication failure. Specifically, the printer's main board cannot properly detect or communicate with the installed fax card. The fax card is a dedicated hardware module that handles fax signal modulation, demodulation, and telephone line interfacing. When the main board polls this card during startup or operation and receives no valid response, it triggers the #10-002 error and halts fax functionality.

The most common root cause is an improperly seated fax card. The card connects to the main board via an edge connector or slot interface, and even slight misalignment can interrupt the data and power signals between the two components. Physical damage to the card's connector pins, oxidation on contact surfaces, or a cracked circuit board can produce the same symptom. In some cases, the fax card may have failed entirely due to an electrical surge through the telephone line.

Diagnosis begins with reseating the fax card, ensuring it is fully and evenly inserted into its connector with no visible gaps. If reseating does not resolve the error, the fax card itself should be replaced. If a known-good replacement card still triggers the #10-002 code, the issue has shifted to the main board, which may have a damaged fax card interface circuit. In that scenario, main board replacement is the recommended corrective action.

Common causes of #10-002

  1. 01

    Fax card not fully seated in connector

    Wiring / connection

    The fax card may have shifted or was never fully inserted into its slot on the main board. Inspect the card to ensure it is evenly pressed into the connector with no rocking or gaps.

  2. 02

    Dirty or oxidized connector contacts

    Wiring / connection

    Corrosion or dust on the fax card's edge connector contacts can break the electrical connection with the main board. Carefully cleaning the contacts may restore communication.

  3. 03

    Failed or damaged fax card

    Part replacement

    The fax card itself may have failed due to a power surge through the phone line or internal component failure. If reseating does not resolve the error, the card should be replaced.

  4. 04

    Damaged fax card connector on main board

    Part replacement

    If the slot or connector on the main board is bent, cracked, or has broken solder joints, the fax card will not make reliable contact even when properly seated. A main board replacement is required in this case.

  5. 05

    Failed main board fax interface circuit

    Part replacement

    If a confirmed working fax card still triggers the #10-002 error, the fax card interface circuitry on the main board has likely failed. This requires replacing the main board.

Frequently asked questions about #10-002

What does #10-002 mean on a Samsung multifunction_printer?
Error #10-002 indicates that the printer's main board cannot detect or communicate with the internal fax card. The fax card is the dedicated hardware module responsible for all fax send and receive operations. This error typically appears at startup or when a fax function is attempted. It means fax capability is unavailable until the issue is resolved.
How do I fix error #10-002 on my Samsung printer?
Start by powering off the printer and reseating the fax card, making sure it is fully and evenly pressed into its connector on the main board. If the error returns after reseating, replace the fax card with a compatible unit. If the error still persists after installing a known-good fax card, the main board will need to be replaced.
Will resetting the printer clear the #10-002 error?
A simple power cycle or factory reset will not permanently clear error #10-002 because it is caused by a hardware detection failure, not a software or settings issue. The error will return unless the fax card is properly reseated or replaced. Resets may temporarily clear the display, but the underlying hardware problem must be addressed.
Is it safe to keep using the printer while error #10-002 is active?
General printing, copying, and scanning functions may still operate normally while this error is present, since it specifically affects the fax module. However, all fax send and receive operations will fail. It is safe to continue using non-fax functions, but the error should be resolved before relying on fax capability.
How much does it cost to fix a Samsung printer showing error #10-002?
If only reseating or cleaning the fax card contacts is needed, there is no parts cost involved. A replacement fax card typically costs in the range of $30 to $80 depending on the specific model. If main board replacement is required, parts and labor costs can range from $150 to $350 or more, which may make professional repair less economical on older units.
