What M1-5612 means on a Samsung multifunction printer

The M1-5612 error code on a Samsung multifunction printer indicates that the MP (Multi-Purpose) tray has been detected as empty. The printer's paper detection system relies on a component called the Actuator-Paper Empty, a mechanical sensor arm that physically contacts the paper stack when media is loaded. When paper is present, this actuator is displaced, signaling the printer's control board that media is ready for feeding. When no paper is detected, or when the actuator fails to register a loaded stack, the status LED turns red and the M1-5612 code is triggered, halting print operations.

The root cause is either genuinely empty media in the MP tray or a defective Actuator-Paper Empty component. The actuator can fail mechanically if the plastic arm becomes broken, warped, or jammed, preventing it from properly registering paper even when the tray is loaded. The associated sensor or its electrical connection can also degrade over time, sending a false empty signal to the printer's logic board. Debris, dust, or small paper fragments caught around the actuator pivot point can also interfere with its range of motion.

Diagnosis begins with the simplest step: confirm the MP tray is loaded with appropriately sized, undamaged paper and that the stack is seated correctly within the tray guides. If the error persists after loading paper, the actuator should be inspected for visible damage, restricted movement, or debris interference. If the actuator arm moves freely but the error remains, replacement of the Actuator-Paper Empty component is the recommended corrective action.

Common causes of M1-5612

  1. 01

    MP Tray Is Actually Empty

    Wiring / connection

    The most frequent cause is simply that the multi-purpose tray has run out of paper. Load the tray with the correct media type and size, ensuring it is aligned within the paper guides.

  2. 02

    Paper Loaded Incorrectly

    Wiring / connection

    Paper that is not seated properly in the MP tray guides may not contact the Actuator-Paper Empty arm, causing a false empty reading. Remove the stack, fan the pages, and reload carefully within the guide rails.

  3. 03

    Defective Actuator-Paper Empty

    Part replacement

    The mechanical actuator arm that detects paper presence can become broken, warped, or stuck in the empty position. Inspect the actuator for physical damage or restricted movement; if faulty, the component requires replacement.

  4. 04

    Debris Around the Actuator

    Wiring / connection

    Dust, torn paper fragments, or foreign material lodged near the actuator pivot point can prevent the arm from moving into the paper-detected position. Carefully clear the area around the actuator and test with freshly loaded paper.

  5. 05

    Sensor Electrical Fault

    Part replacement

    If the actuator moves freely but the error persists, the electrical connection between the paper-empty sensor and the control board may be degraded or intermittent. Inspect wiring and connectors associated with the MP tray sensor assembly.

Frequently asked questions about M1-5612

What does M1-5612 mean on a Samsung multifunction_printer?
The M1-5612 code means the printer has detected that the multi-purpose (MP) tray is empty of paper. The status LED will turn red and printing will stop. This is triggered either by an actual empty tray or by a failed Actuator-Paper Empty sensor component that incorrectly reports the tray as empty.
How do I fix the M1-5612 error on my Samsung printer?
Start by loading paper into the MP tray and ensuring it is properly aligned within the tray guides. If the error clears, the issue was simply an empty or misloaded tray. If the error persists with paper loaded, inspect the Actuator-Paper Empty component for damage, debris, or restricted movement, and replace it if it is found to be defective.
Will resetting my Samsung printer clear the M1-5612 error?
A power cycle or reset may temporarily clear the error display, but the code will return if the underlying cause is not addressed. If the MP tray is empty or the paper is incorrectly loaded, the error will reappear on the next print job. A defective Actuator-Paper Empty sensor will continue triggering the code until the component is repaired or replaced.
Is it safe to continue using my printer when the M1-5612 error is showing?
The printer will halt operation when this error is active, so normal printing will not proceed. There is no safety risk to the user from this specific error, as it is a paper detection fault rather than an electrical or heat-related issue. You can safely load paper or inspect the actuator without any hazard, though the printer will not function until the condition is resolved.
How much does it cost to fix the M1-5612 error if the actuator is defective?
If the fix is simply reloading paper, there is no cost involved. If the Actuator-Paper Empty component needs replacement, costs will vary depending on parts availability and whether you perform the repair yourself or use a technician. Parts and labor for a sensor actuator replacement on a multifunction printer typically fall in the range of $20 to $100 or more, depending on the specific model and service provider.
