OKI MC332, MC362 and MC562 Does Not Print over the Network or Shows “Offline”: How to Fix It

Last Updated on 07.08.2026 by DriverNew

If the OKI MC332, MC362 or MC562 previously printed over the network and then changed to “Offline”, do not start by removing the driver. In most cases, Windows is sending print jobs to a WSD port or to an old IP address that no longer belongs to the MFP. As a result, the device may be accessible from a browser and may still scan, but print jobs remain in the queue.

Below you will find instructions on how to identify the cause, check whether the MFP is accessible, and switch the installed driver to a Standard TCP/IP Port. For direct network printing, this series supports the RAW protocol and port 9100.

Models This Guide Applies To

This guide applies to the network versions of the following devices:

• OKI MC332dn;
• OKI MC342dn and MC342dw;
• OKI MC352dn;
• OKI MC362dn and MC362w;
• OKI MC562dn, MC562w and MC562dw;
• OKI ES3452 MFP;
• OKI ES5462 MFP and ES5462dw MFP;
• OKI MPS2731mc.

Wireless connectivity is available only on Wi-Fi models, such as MC342dw, MC362w, MC562w and MC562dw. The other listed devices connect to the network using an Ethernet cable. Model variant names may differ depending on the country.

How to Identify the Likely Cause by the Symptoms

Step 1. Print the Network Information and Write Down the IP Address

The report must be printed from the MFP control panel, not from Windows. This gives you the device’s current address even if the computer is using old settings.

1. Press the SETTING button on the control panel.
2. Select Reports and press OK.
3. Select System and press OK.
4. Select Network Information and press OK.
5. Select Yes and press OK.

In the printed report, find and write down:

• IPv4 Address — the current address of the MFP;
• Subnet Mask — the subnet mask;
• Gateway Address — the gateway address;
• MAC Address — the hardware address of the network interface.

If the report cannot be printed from the control panel, resolve the error shown on the MFP: a paper jam, an open cover, missing consumables or another hardware problem. In this situation, Windows settings are not the primary cause.

Step 2. Check Whether the MFP Is Accessible from the Computer

Check Using a Browser

1. Connect the computer to the same local network as the MFP.
2. Open a browser.
3. Enter http:// followed by the IPv4 address from the report in the address bar. For example:

http://192.168.1.50

If the built-in OKI web page opens, the computer can see the device over the network. Continue with checking the Windows queue and port.

If the page does not open, do not reinstall the driver. First perform the checks in the following section.

Check Print Port 9100

This test shows whether the MFP accepts a direct network connection for printing.

1. Open the Start menu and type PowerShell.
2. Run Windows PowerShell or open the PowerShell profile in the Terminal app. Administrator privileges are not required.
3. Enter the command below, replacing the example address with your MFP’s address:

Test-NetConnection 192.168.1.50 -Port 9100

Find the TcpTestSucceeded line:

• True — the MFP is accessible and print port 9100 is responding;
• False — a connection to port 9100 could not be established.

If the built-in web page opens but the test returns False, check whether TCP/IP and Port9100 are enabled in the MFP’s network settings. Traffic filtering between network segments may also be the cause. Do not completely disable Windows Firewall or antivirus software for this test.

If the MFP’s Web Page Does Not Open

When Connected by Ethernet Cable

1. Make sure the cable is connected to the MFP’s network connector and to the router or network switch.
2. Disconnect and reconnect both ends of the cable.
3. Check the network connector indicators. If they do not light up, try another cable and another router port.
4. Restart the MFP and router, then print the network information again.
5. Compare the first parts of the computer’s and MFP’s addresses. For example, addresses 192.168.1.25 and 192.168.1.50 are usually on the same home subnet when the mask is 255.255.255.0.

When Connected over Wi-Fi

1. Make sure your OKI model variant actually supports Wi-Fi.
2. Check the network report and make sure the wireless connection status is Connected and that it is connected to the correct network.
3. Do not connect the computer to a guest Wi-Fi network. In guest mode, devices are often isolated from each other.
4. If a VPN is active on the computer, temporarily disconnect it and check the MFP’s local address again.
5. If necessary, reconnect the MFP to the wireless network and print the network information again.

Check for Duplicate IP Addresses

Two devices with the same IP address may alternately become available and disappear from the network. For a quick check:

1. Write down the MFP’s IP address.
2. Turn the MFP completely off.
3. Wait about one minute and run the following command in Terminal:

ping 192.168.1.50

If the MFP is turned off but replies continue to come from this address, another device has probably been assigned the same address. Free the conflicting address or assign the MFP a different permanent address. No reply by itself does not prove that the address is free: some devices block ping responses.

Step 3. Disable Pause and Offline Mode in Windows

Windows 11

1. Open Start > Settings > Bluetooth & devices > Printers & scanners.
2. Select the required OKI queue.
3. Click Open print queue.
4. Open the Printer menu.
5. If Pause Printing or Use Printer Offline is checked, clear the check box.
6. Remove old jobs from the queue. Then try printing one page.

Windows 10

1. Open Start > Settings > Devices > Printers & scanners.
2. Select the OKI printer and click Open queue.
3. In the Printer menu, clear Pause Printing and Use Printer Offline if they are selected.
4. Cancel the remaining jobs in the queue and try printing again.

If a job cannot be removed, press Win + R, enter services.msc and press Enter. Find the Print Spooler service, right-click it and select Restart. After restarting the service, clear the queue again.

If offline mode immediately returns after you clear the check box, continue to the port check. Repeatedly enabling and disabling the command will not fix an incorrect IP address or a WSD port.

Step 4. Check Which Port the Printer Uses

How to Open Printer Properties in Windows 11

1. Open Settings > Bluetooth & devices > Printers & scanners.
2. Select the required OKI printer.
3. Click Printer properties.
4. If this command is not available, press Win + R, enter control printers and press Enter. In the window that opens, right-click the OKI printer and select Printer properties.
5. Open the Ports tab.

How to Open Printer Properties in Windows 10

1. Open Settings > Devices > Printers & scanners.
2. Select the OKI printer and click Manage.
3. Click Printer properties.
4. Open the Ports tab.

Find the row with the selected check box and compare it with the following options:

• WSD-… — a WSD port is being used. If printing stops after sleep mode or the device periodically goes offline, create a Standard TCP/IP Port.
• IP_192.168… or Standard TCP/IP Port — open the port configuration and compare the address with the MFP report.
• USB001 — the queue is configured for USB rather than network printing.
• FILE:, LPT1: or another non-network port — the wrong queue or wrong port is selected.

Do not enable Enable printer pooling. This feature is intended for a pool of identical printers and may send jobs to another selected port.

Step 5. Correct the Address of an Existing Standard TCP/IP Port

Follow these steps if a Standard TCP/IP Port is already selected but it contains an old address.

1. On the Ports tab, select the checked TCP/IP port.
2. Click Configure Port.
3. In the Printer Name or IP Address field, enter the current IPv4 address from the network report.
4. Under Protocol, select RAW.
5. Set the port number to 9100.
6. Initially, leave SNMP Status Enabled selected.
7. Click OK, then Apply.
8. On the General tab, click Print Test Page.

The port name may still contain the old numbers, for example IP_192.168.1.40, even if the address in its settings has already been changed to 192.168.1.50. For printing, the address in the Configure Port window is what matters; renaming the port is not required.

Step 6. Replace WSD with a Standard TCP/IP Port

First create and test the new port. Do not remove the old WSD port or the previous queue until you have successfully printed a test page.

1. Open Printer properties > Ports.
2. Click Add Port.
3. In the list of port types, select Standard TCP/IP Port.
4. Click New Port, then Next.
5. In the Printer Name or IP Address field, enter the IPv4 address from the report. The port name will be filled in automatically.
6. Click Next and wait while the device is checked.
7. If the additional port information window appears, select Custom and click Settings.
8. Select the RAW protocol, enter port number 9100 and click OK.
9. Finish the wizard by clicking Finish, then close the port type selection window.
10. On the Ports tab, make sure the check box next to the new TCP/IP port is selected.
11. Click Apply.
12. Open the General tab and click Print Test Page.

If the test page prints successfully, rename the queue so that it can easily be distinguished from the automatically created WSD queue, for example OKI MC562 TCP-IP. Then set it as the default printer. Remove the old queue only after checking printing from several programs.

Step 7. Check SNMP If Windows Incorrectly Shows “Offline”

Standard TCP/IP Port uses SNMP to obtain paper, cover and other status information. Sometimes printing over TCP port 9100 is available, but the SNMP response cannot pass through the router, firewall or a separate network segment. Windows may then incorrectly consider the printer offline.

Check SNMP only when both of the following conditions are met:

• the Test-NetConnection command shows TcpTestSucceeded: True;
• the IP address in Standard TCP/IP Port exactly matches the MFP’s address.

1. Open Printer properties > Ports.
2. Select the Standard TCP/IP Port being used.
3. Click Configure Port.
4. Clear the SNMP Status Enabled check box.
5. Click OK and Apply.
6. Wait a few seconds and print a test page.

If printing starts working after this change, you can leave SNMP status monitoring disabled. The printer will continue to print, but Windows may display its status less accurately. On a business network, it is better to resolve the SNMP blocking between the computer and the MFP and then enable this option again.

Installing the optional SNMP component in Windows is not required for this test. The check box in Standard TCP/IP Port settings controls network printer polling; it does not start a separate SNMP service on the computer.

If disabling SNMP makes no difference, select the check box again: the cause is elsewhere.

Step 8. Make the MFP’s IP Address Permanent

If the port started working after you entered the new address, but the MFP’s address changes periodically, reserve it. The safest option for a home or small office network is DHCP reservation in the router.

1. Open the router’s management page.
2. Find the LAN, DHCP, Address Reservation, Static Lease section or a similarly named section.
3. Add the MFP’s MAC address from the network report.
4. Reserve its current IPv4 address or another available address on the local network.
5. Save the settings and restart the MFP’s network connection.
6. Print the network information again and make sure the address has not changed.

If the address changes after it has been reserved, open the Windows TCP/IP port configuration again and enter the final address. If network scanning is also used, check any programs where the MFP was registered using the previous IP address.

If Standard TCP/IP Port Is Configured Correctly but Printing Still Does Not Work

Check the results of the previous steps in the following order:

1. The network report prints from the control panel. This means the printing mechanism is capable of producing a page.
2. The built-in OKI web page opens using the current IP address. This means the computer can see the MFP on the network.
3. The TCP port 9100 test returns True. This means the direct printing service is available.
4. Printer properties show a Standard TCP/IP Port with the same address, RAW and 9100. This means Windows is sending data to the correct network destination.

If all four checks are successful but a test page still does not print, create a second queue using the model-specific OKI driver and assign it to the already tested TCP/IP port. Do not remove the old queue until the new one successfully prints a test page. If the new queue works, the problem was in the previous queue or its driver, not in the network.

If port 9100 is inaccessible from only one computer, compare its network connection, VPN, security rules and subnet number with a computer from which printing works. If the port is inaccessible from all computers, check TCP/IP and Port9100 settings on the MFP, network isolation and IP address filtering. Completely disabling the firewall, resetting the MFP to factory settings and assigning a random static address should not be the first troubleshooting steps.
