o Is 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.
o Does 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 133.
o 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. 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.
o Is 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.
o Are the network settings correct?
Ask your network administrator for the network settings.
o 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 on the network environment. Ask your system administrator, or refer to the
manual for your network system. If you cannot print via USB, see the appropriate section in this User’s Guide.
o Confirm if errors have occurred in the printer by checking the lights and messages on the printer's control
panel.
See “Control Panel” on page 15 and “When a Message is Displayed” on page 120.
o Confirm the printer operation.
Print a test pattern. Test patterns can be printed without connecting the printer to a computer and hence can be used to
check printer function and status. See “Checking for Clogged Nozzles” on page 81.
Refer to the following section for information on what to do if the pattern does not print correctly.
