Network Connection Problems

  • Common to Windows and Mac

Cause

Solution

Reference

Using a cross cable.

Use a straight cable.

-

The machine was turned on before a cable was connected.

Connect cables before turning the machine on.

Connecting a LAN Cable

There is a problem with the compatibility with the hub.

Press the scroll button on the operator panel to select [Admin Setup] > [Network Setup] > [HUB Link Setting], and then change the setting.

Solution

Reference

The IP address is incorrect.

  • Check that the same IP address is set for the machine and the machine's port setting on the computer.

  • Check that the IP address is not duplicated by another device.

  • Check that the correct IP address, subnet mask, and gateway address are set.

  • If using OKI LPR Utility, check the IP address setting with OKI LPR Utility.

Wireless LAN is Not available (Infrastructure)

At Print Network Information and Wireless(Infrastructure) Information, check the following explanation while checking the items numbered (1) to (6) in the figure below.

To print Network Information, select [Functions] > [Print Information] > [Network].

  • Unable to connect to an access point ( indicates the status other than "Connected".)

Cause

Solution

Reference

[Wireless(Infrastructure)] indicates "Disable".

* Refer to as shown above.

Select [Enable] for [Wireless(Infrustructure)].

* You cannot enable wireless LAN (infrastructure) and wireless LAN (AP mode) at the same time.

Connecting to an Access Point (Infrastructure)

[SSID] is incorrect. Or it is blank.

* Refer to as shown above.

Check whether the SSID of the desired wireless LAN access point is correct.

If it is blank, the SSID is not set.

Connecting to an Access Point (Infrastructure)

[Security] is incorrect.

* Refer to as shown above.

Check whether to correspond with the security (ciphering method) of the desired wireless LAN access point.

Connecting to an Access Point (Infrastructure)

The encryption key is incorrect.

Check whether to correspond with the encryption key of the desired wireless LAN access point.

Connecting to an Access Point (Infrastructure)

The desired wireless LAN access point is set to Channel 12 or 13.

The printer does not support Channel 12 and 13.

Change the channel setting of the wireless LAN access point.

-

  • Network communication is Not stable

Cause

Solution

Reference

RSSI is low.

* Refer to as shown above.

The received signal strength is weak.

Install this machine in a place with a good view of the wireless access point. (We suggest that the distance between the machine and the wireless device be 30 m or less.)

Do not place any electric appliances that emit weak radio waves (such as microwaves or digital cordless telephones) close to the machine.

If there is metal, aluminum sash, or a reinforced concrete wall between the machine and wireless access points, connections may be harder to be established.

-

The frequency band you are using is congested.

* Refer to as shown above.

When [Band] is 2.4 GHz and the wireless LAN access point supports 5 GHz, change to the 5 GHz SSID.

When [Band] is 5 GHz, change the wireless LAN access point to be connected to 2.4 GHz SSID.

Connecting to an Access Point (Infrastructure)

  • Able to connect to an access point but network communication is Not available

Cause

Solution

Reference

The IP address is the same segment as the wired network.

The printer can use the wired LAN and wireless LAN simultaneously. However, if a wired LAN and wireless LAN are connected to the same subnet, the communication may be unstable.

-

[Enabling Default Gateway] is set to [Wired].

To communicate with a device out of the segment using the wireless LAN, press the scroll buttonon on the operator panel, select [Admin Setup] > [Network Setup] > [Enabling Default Gateway], and then select [Wireless(Infrastructure)].

In that case, the printer cannot communicate with a device out of the segment using the wired LAN.

* To check the [Enabling Default Gateway] status, select [General Information] > [Enabling Default Gateway].

Selecting a connecting method between different segments

Wireless LAN is Not available (AP Mode)

At Print Network Information and Wireless(AP Mode) Information, check the following explanation while checking the items numbered (1) to (6) in the figure below.
