Samsung Error U2-1113 — What It Means & How to Fix It
By Ryan Green · Updated August 2026 · Independent guide · PrinterCare USA LLC (not affiliated with any printer manufacturer)
The U2-1113 error on Samsung printers is frustrating because it prevents you from scanning documents, even if your printer's other functions work fine. This specific error code points directly to the scan unit—the component responsible for reading and digitizing your documents—and it means either that hardware has failed or the printer has lost communication with it.
The good news is that this error has several fixable causes, and most of them you can address without calling for service. We'll walk you through the troubleshooting steps in order of difficulty, starting with the quickest resets and moving toward component-level solutions.
How to fix it — step by step
- Perform a Hard Power Reset. Turn off the printer using the power button on the front panel, then unplug the power cable from the wall outlet. Wait for 30 seconds to allow all capacitors to fully discharge. Plug the printer back in and turn it on, then attempt a test scan to see if the error clears.
- Check the Scan Unit Cable Connection. Open the printer's top cover to access the scan unit area. Look for the ribbon cable connecting the scan unit to the main logic board—it typically runs from the scanner assembly down toward the printer's motherboard. Gently reseat this cable by unplugging it and plugging it back in firmly until you hear or feel a click.
- Clean the Scan Unit Contacts. With the printer powered off and the top cover open, use a dry cotton swab or lint-free cloth to gently clean the metal contacts on both the scan unit cable connector and the port on the logic board. Dust and oxidation on these contacts can prevent proper communication. Allow them to air dry for one minute before reseating the cable.
- Reset the Printer to Factory Defaults. Navigate to the printer's menu using the control panel buttons on the front of the machine. Look for Settings or Maintenance, then find the option to Restore Factory Defaults or Reset All Settings. Confirm the reset, which will reboot the printer and may clear temporary errors in the scan unit's firmware.
- Update or Reinstall the Scanner Driver on Your Computer. Go to the Samsung support website and search for your exact printer model number. Download the latest scanner driver for your operating system, whether Windows 11 or macOS. Uninstall the current scanner driver from your computer's device manager or system preferences, restart your computer, then install the new driver and test scanning again.
- Inspect the Scan Unit for Physical Damage. With the printer powered off and the top cover open, visually examine the scan unit—the component beneath the lid that contains mirrors and sensors. Look for any broken plastic, loose internal parts, or debris. Gently remove any visible dust or paper fragments using a can of compressed air held at least six inches away.
- Check for Firmware Updates. Connect your printer to your network and access its web interface by entering the printer's IP address into a web browser. Navigate to the Settings or Maintenance section to check for available firmware updates. If an update is available, download and install it, as Samsung occasionally releases firmware patches that resolve scan unit communication errors.
- Request Professional Diagnosis if Error Persists. If the error U2-1113 continues after all previous steps, the scan unit hardware has likely failed and requires replacement. Contact a certified Samsung service center or use a remote technician service for approximately forty-nine dollars to have the unit diagnosed and a replacement scan unit installed properly.

Frequently asked questions
Does error U2-1113 mean my printer is completely broken?
No. This error only affects the scanner function of your printer. Your printing, copying, and faxing capabilities should still work normally. The error specifically indicates a problem with just the scan unit, which is a separate component from the print engine.
Can I fix this error without opening the printer?
You can attempt the first few fixes, such as a hard power reset, checking your driver, and updating firmware, all without opening the printer. However, if those steps do not resolve the issue, you will need to open the top cover to inspect the scan unit cable and connections.
How much will a replacement scan unit cost?
A genuine Samsung replacement scan unit typically costs between one hundred twenty dollars and three hundred dollars, depending on your printer model, plus labor if you use a service technician. Remote diagnostics to confirm the need for replacement usually run around forty-nine dollars.
Will the error go away on its own if I just leave the printer off for a while?
Temporarily leaving the printer off might clear the error if it is a temporary firmware glitch, but if you power it back on and the error returns immediately, it indicates a persistent hardware or communication problem that requires troubleshooting. A simple 30-second reset is more effective than leaving the printer off for hours.
