If you cannot print via USB, see the appropriate section in this User's Guide. 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.

U “Control panel” on page 14 U “When a Message is Displayed” on page 100 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. U “Specifications Table” on page 126 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 Confirm the printer operation. Print a check pattern. Check patterns can be printed without connecting the printer to a computer and hence can be used to check printer function and status. U “How to Print a Nozzle Check Pattern” on page 72 Refer to the following section for information on what to do if the pattern does not print correctly.
