When You Cannot Print

Cause

Solution

The power is off.

For details about how to turn on the power, see "Turning On/Off the Power", Getting Started.

The cause is displayed on the screen of the control panel.

Check the error message or warning status on the display panel, and then take the required action. For details about solutions, see Messages Displayed When You Use the Printer Function.

The interface cable is not connected correctly.

For details about how to connect interface cables correctly, see "Connecting to the Interface", Connecting the Machine/ System Settings.

The correct interface cable is not being used.

The type of interface cable you use depends on the computer. Be sure to use the correct one. If the cable is damaged or worn, replace it. For details about the interface cable, see "Connecting to the Interface", Connecting the Machine/ System Settings.

The interface cable was connected after the power was turned on.

Connect the interface cable before turning on the power.

The machine is executing maintenance operations.

The machine may perform periodic maintenance while running if it has been left unused for an extended period of time. Wait until the machine is ready, and then try to print again.

If the machine is using wireless LAN, a weak wireless signal might result in print failures.

Check the radio signal status of the wireless LAN in [System Settings]. If signal strength is not satisfactory, move the machine to a location where radio waves travel, or remove objects that might cause interference.

You can check signal status only when wireless LAN is used in infrastructure mode. For details about the radio signal status of the wireless LAN, see "Interface Settings", Connecting the Machine/ System Settings.

If the machine is using a wireless LAN (IEEE 802.11b/g/n) or radio waves may be interfering with wireless communication. This may occur if there is a microwave oven, cordless telephone, industrial machine, scientific instrument, or medical instrument using the same frequency range near the device.

Turn off other machines or instruments which use the same frequency range, and then print again. If printing is successful after you turn off the power, then it is possible these devices are the cause of the interference. Move the devices to a location where they do not interfere.

If the machine is using wireless LAN, SSID settings are incorrect.

Check that the SSID is correctly set by using the machine's display panel. For details about SSID setting, see "Wireless LAN", Connecting the Machine/ System Settings.

If the machine is using wireless LAN, the receiver's MAC address may be preventing communication with the access point.

Check access point settings when wireless LAN is used in the infrastructure mode. Depending on the access point, client access may be limited by MAC address. Also, check there are no transmission problems between access point and wired clients, and between access point and wireless clients.

The login user name, login password, or driver encryption key is invalid.

Check the login user name, login password, or driver encryption key.

Advanced encryption has been set using the extended security function.

Check the extended security function settings. For details about extended security function settings, see "Specifying the Extended Security Functions", Security Guide.

A mechanical error might have occurred.

Contact your service representative.

Transmission mode is not configured correctly when wireless LAN is used in ad hoc mode.

  • Turn off the power, and then turn it on again. For details about how to turn on and off the power, see "Turning On/Off the Power", Getting Started.

  • Change [Communication Mode] in [System Settings] to [802.11 Ad-hoc Mode], and then select [Off] for [Security Method]. For details about Communication Mode, see "Interface Settings", Connecting the Machine/ System Settings.

When the Data In indicator does not light up or flash after a print job starts, data is not being sent to the machine.

  • When a cable is used to connect the computer directly to the machine, check whether the print ports are configured correctly.

  • When the computer is connected to the network, ask your administrator about the computer's network connection.

If printing does not start, contact your service representative.
