Samsung Multifunction Printer Error Code S2-4110

The S2-4110 error means the printer has detected that a door or cover is open, or the switch that monitors door status has failed. The status LED turns red and printing stops until the condition is resolved. The error involves a signal path between the cover open switch, the main board, and the HVPS board.

A power cycle or reset may temporarily clear the error display, but the code will return immediately if the underlying cause is not addressed. If a door is not properly closed or the switch is defective, the printer will continue to detect the fault every time it checks door status. A reset is not a fix for this error.

If the fix is simply reseating a door or a connector, there is no parts cost involved. If the cover open switch needs replacement, parts typically range from a few dollars to around $20 to $40 depending on the model. If the HVPS board or main board connection wiring has failed, repair costs including labor could range from $50 to $150 or more, depending on service rates in your area.

Start by firmly closing both the front and rear doors, pressing until the latch clicks into place. If the error remains, inspect the wiring connector between the main board and HVPS board for looseness or damage and reseat it. If those steps do not resolve the issue, the cover open switch itself may need to be tested and replaced.

No. The printer is designed to stop operation when this error is active because the HVPS board will not enable high-voltage output until all doors are confirmed closed. Attempting to bypass or ignore this safety interlock could expose internal components to damage and poses a risk to the user. The error should be resolved before resuming printing.
