Troubleshooting

You cannot print (because the printer does not work)

The printer does not turn on.

The printer is not communicating with the computer.

You cannot print under the network environment.

oIs the power cable plugged into the electrical outlet or the printer?
Make sure the power cable is securely plugged into the printer.
oIs there any problem with the electrical outlet?
Make sure your outlet works by connecting the power cable for another electric product.
oIs the cable plugged in properly?
Make sure the printer's interface cable is securely plugged into the correct terminal of the computer and the printer. Also,
make sure the cable is not broken nor bent. If you have a spare cable, try connecting with the spare cable.
oDoes the interface cable specification match the specifications for the computer?
Make sure the interface cable specifications match the specifications for the printer and the computer.
See “Specifications Table” on page 180.
oIs the interface cable connected directly to the computer?
If you use a printer switching device or extension cable between the printer and the computer, you may not able to print
depending on the their combinations. Connect the printer and the computer directly with the interface cable and check if you
can print normally.
oWhen using a USB hub, is it being used correctly?
In the USB specification, daisy-chains of up to five USB hubs are possible. However, we recommend that you connect the
printer to the first hub connected directly to the computer. Depending on the hub you are using, the operation of the printer
may become unstable. If this should occur, plug the USB cable directly into your computer's USB port.
oIs the USB hub recognized correctly?
Make sure the USB hub is recognized correctly on the computer. If it has, disconnect the USB hub from the computer and
connect the computer directly to the printer. Ask the USB hub manufacturer about USB hub operation.
oAre the network settings correct?
Ask your network administrator for the network settings.
