What to do
Is the power cord plugged into the electrical outlet or the printer?
Make sure the power cord is securely plugged into the printer.
Is there any problem with the electrical outlet?
Make sure your outlet works by trying to connect the power cord of another electric
product.
Is the cable plugged properly?
Make sure the printer's interface cable is securely plugged into the correct terminal of
the computer. Also, make sure the cable is not broken nor bent. If you have a spare
cable, try with the spare cable.
Does the interface cable specification match the specifications for the computer?
Make sure the interface cable specifications match the specifications for the printer
and computer.
See "Interface" on page 114
Is the interface cable directly connected to the computer?
Make sure the interface cable is directly connected to the computer without passing
through any device, such as a printer switching device, or extension cable.
When 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. Also, some hubs may cause unstable operation. If problems occur, connect
the printer directly to the USB port of the computer.
Is the USB hub recognized correctly?
Make sure the USB hub is recognized correctly in the computer. If the USB hub is
recognized correctly, unplug all of the USB hubs from the computer's USB port, and
then connect the printer's USB connector directly to the computer's USB port. Ask the
USB hub manufacturer about USB hub operation.
Are the network settings correct?
Ask your network administrator for the network settings.
Connect the printer directly to the computer using a USB cable, and then try to print.
If you can print via USB, there are some problems with the network environment. Ask
your system administrator, or refer to the manual for your network system. If you
cannot print, see the appropriate section in this manual.
Confirm if errors have occurred in the printer by checking the lights and
messages on the printer's control panel.
