Suggested solutions

Printers Not Found

  • Your machine may not be turned on. Turn on your computer and the machine.

  • USB cable is not connected between your computer and machine. Connect the machine to your computer using the USB cable.

  • The machine does not support wireless networking. Check the machine's user's guide included on the software CD supplied with your machine and prepare a wireless network machine.

Connecting Failure - SSID Not Found

  • The machine is unable to find the network name (SSID) you have selected or entered. Check the network name (SSID) on your access point and try connecting again.

  • Your access point is not turned on. Turn on your access point.

Connecting Failure - Invalid Security

  • Security is not configured correctly. Check the configured security on your access point and machine.

Connecting Failure - General Connection Error

  • Your computer is not receiving a signal from your machine. Check the USB cable and your machine’s power.

Connecting Failure - Connected Wired Network

  • Your machine is connected with a wired network cable. Remove the wired network cable from your machine.

Connecting Failure - Assigning the IP address

  • Cycle the power for the access point (or wireless router) and machine.

PC Connection Error

  • The configured network address is unable to connect between your computer and machine.

    • For a DHCP network environment

      The printer receives the IP address automatically (DHCP) when computer is configured to DHCP.

      [Note]

      If the printing job is not working in DHCP mode, the problem may be caused by the automatically changed IP address. Compare the IP address between the product's IP address and the printer port's IP address.

      How to compare:

      1. Print the network information report of your printer, and then check the IP address (see Printing a network configuration report).

      2. Check the printer port's IP address from your computer.

        1. Click the Windows Start menu.

        2. Select Start > Programs or All Programs > Samsung Printers > Samsung Printer Center.

          • For Windows 8

            From the Charms, select Search > Apps > Samsung Printers > Samsung Printer Center.

          • Windows 10 / Windows Server 2016

            From task bar, type in Samsung Printers in Search input area. Press the Enter key and then select Samsung Printer Center.

            OR

            From the Start () icon, select All apps > Samsung Printers> Samsung Printer Center.

        3. Click your machine.

        4. Press Properties.

        5. Click Port tab.

        6. Click Configure Port.. button.

        7. Check if Printer Name or IP Address: is the IP address on the network configuration Sheet.

      3. Change the printer port's IP address if it is different from the network information report's.

        If you want to use the software installation CD to change the port IP, connect to a network printer. Then reconnect the IP address.

PC Connection Error

  • For a Static network environment

    The machine uses the static address when the computer is configured to static address.

    For example,

    If the computer’s network information is as shown below:

    • IP address: 169.254.133.42

    • Subnet Mask: 255.255.0.0

    Then the machine’s network information should be as below:

    • IP address: 169.254.133.43

    • Subnet Mask: 255.255.0.0 (Use the computer’s subnet mask.)

    • Gateway: 169.254.133.1

Other problems

If problems occur while using the machine on a network, check the following:

[Note]

For information on the access point (or wireless router), refer to its own user's guide.

  • Your computer, access point (or wireless router), or machine may not be turned on.

  • Check the wireless reception around the machine. If the router is far from the machine or there is an obstacle, you might have difficulty receiving the signal.

  • Cycle the power for the access point (or wireless router), machine, and computer. Sometimes cycling the power can recover network communication.

  • Check whether firewall software (V3 or Norton) is blocking the communication.

    If the computer and the machine are connected on the same network and it cannot be found when searching, firewall software might be blocking the communication. Refer to the user's guide for the software to turn it off and try searching for the machine again.

  • Check whether the machine's IP address is allocated correctly. You can check the IP address by printing the network configuration report.D

  • Check whether the access point (or wireless router) has a configured security (password). If it has a password, refer to the access point (or wireless router) administrator.

  • Check the machine's IP address. Reinstall the machine driver and change the settings to connect to the machine on the network. Due to the characteristics of DHCP, the allocated IP address could change if the machine is not used for a long time or if the access point has been reset.

    Register the product's MAC address when you configure the DHCP server on the access point (or wireless router). Then you can always use the IP address that is set with the MAC address. You can identify the Mac address of your machine by printing a network configuration report.

  • Check the wireless environment. You might not be able to connect to the network in the infrastructure environment where you need to type in a user's information before connecting to the access point (or wireless router).

  • This machine only supports IEEE 802.11 b/g/n and Wi-Fi. Other wireless communication types (e.g., Bluetooth) are not supported.

  • The machine is within the range of the wireless network.

  • The machine is located away from obstacles that could block the wireless signal.

    Remove any large metal objects between the access point (or wireless router) and the machine.

    Make sure the machine and wireless access point (or wireless router) are not separated by poles, walls, or support columns containing metal or concrete.

  • The machine is located away from other electronic devices that may interfere with the wireless signal.

    Many devices can interfere with the wireless signal, including a microwave oven and some Bluetooth devices.

  • Whenever the configuration of your access point (or wireless router) changes, you must do the product's wireless network setup again.

  • The maximum number of devices that can be connected via Wi-Fi Direct is 4.

  • If the access point is set to work with the 802.11n standard only, it may not connect to your machine.
