What M1-5112 means on a Samsung multifunction printer

The M1-5112 error code on a Samsung multifunction printer indicates that Tray 1 is detected as empty of paper. The printer's paper detection system relies on a mechanical sensor component called the Actuator-Paper Empty, which is a small pivoting flag or lever positioned inside the tray assembly. When paper is loaded, the stack physically deflects this actuator, and the sensor registers the tray as loaded. When no paper is present, the actuator returns to its default position, triggering the empty status signal. The status LED will illuminate red to alert the user that printing cannot proceed.

The most straightforward cause of this error is simply that Tray 1 has run out of paper during a print job or was never loaded before one was initiated. However, if the tray is loaded with paper and the error persists, the Actuator-Paper Empty component itself is likely defective. This can occur due to a broken pivot point on the actuator flag, a spring that has lost tension, or debris preventing the actuator from moving freely into the correct position when paper is inserted.

Diagnosing between an empty tray and a failed actuator is straightforward: load a fresh stack of paper in Tray 1 and observe whether the error clears. If the error remains with paper correctly loaded, physically inspect the actuator for damage, deformation, or obstruction. A stuck or broken actuator will not communicate the correct tray status to the printer's control board, and replacement of the Actuator-Paper Empty component will be required to restore normal operation.

Common causes of M1-5112

  1. 01

    Tray 1 is empty or not loaded

    Wiring / connection

    The most common cause is simply that the printer ran out of paper or no paper was loaded before sending a print job. Load an appropriate stack of paper into Tray 1 and confirm it is seated correctly.

  2. 02

    Defective Actuator-Paper Empty

    Part replacement

    If paper is correctly loaded but the error persists, the Actuator-Paper Empty sensor flag is likely broken, stuck, or deformed and is not registering the presence of paper. Visual inspection of the actuator inside the tray cavity will reveal physical damage or a failure to pivot correctly.

  3. 03

    Paper not seated properly in the tray

    Wiring / connection

    Paper loaded unevenly or not pushed fully into the tray guides may fail to depress the actuator flag sufficiently to trigger the loaded state. Remove the paper, fan the stack, and reload it flush against the tray guides.

  4. 04

    Debris or obstruction blocking the actuator

    Wiring / connection

    Small pieces of torn paper, dust buildup, or foreign material can prevent the actuator from pivoting into the correct position even when paper is present. Inspect the tray cavity and clear any debris around the sensor flag area.

  5. 05

    Broken actuator spring or pivot point

    Part replacement

    The actuator relies on a small spring or integrated flex point to return to position and make consistent contact. If this spring is dislodged or the pivot is cracked, the actuator will not function reliably and the component must be replaced.

Frequently asked questions about M1-5112

What does M1-5112 mean on a Samsung multifunction_printer?
The M1-5112 code means the printer has detected that Tray 1 is empty of paper and cannot continue printing. The status LED will turn red to indicate the problem. The detection is handled by a component called the Actuator-Paper Empty, which physically senses whether paper is present in the tray. If loading paper does not clear the code, that actuator component may be defective.
How do I fix the M1-5112 error on my Samsung printer?
Start by loading a fresh, properly fanned stack of paper into Tray 1, making sure it is aligned with the tray guides and fully seated. If the error clears, normal operation should resume. If the error remains with paper loaded, inspect the Actuator-Paper Empty inside the tray cavity for damage, obstructions, or a broken pivot, and replace it if defective.
Will resetting the printer clear the M1-5112 error?
A simple power cycle or reset will not permanently clear the M1-5112 error if the underlying cause is still present. If the tray is empty, load paper first before restarting. If the actuator is defective, the error will return after any reset until the faulty component is replaced.
Is it safe to continue using the printer with the M1-5112 error showing?
The M1-5112 error is not a safety hazard in terms of electrical risk or fire danger. However, the printer will not be able to execute print jobs while this error is active, so continued use is simply not possible until paper is loaded or the defective actuator is replaced. There is no risk of damaging other printer components by addressing this error.
How much does it cost to repair the M1-5112 error if the actuator needs replacement?
If the fix is simply loading paper, there is no parts cost. If the Actuator-Paper Empty component needs replacement, the part itself is generally inexpensive, typically in the range of a few dollars to around fifteen to thirty dollars depending on the specific model and supplier. Labor costs for a technician to perform the replacement would add to that total, potentially bringing the overall repair into the range of fifty to one hundred dollars or more at a service center.
