Solve problems checklist
If the product is not responding correctly, complete the steps in the following checklist, in order. If the
product does not pass a step, follow the corresponding troubleshooting suggestions. If a step resolves the
problem, you can stop without performing the other steps on the checklist.
1. The control-panel display and LEDs may be off if the product is in Sleep Mode. If the device does not
respond to a key press, then it is either not in Sleep Mode or will now come out of Sleep Mode. If no LEDs
are illuminated or the control-panel display does not come on, use the Power-on checks section in the
product service manual to troubleshoot the problem.
2. Check the cables.
a. Check the cable connection between the product and the computer or network port. Make sure
that the connection is secure.
b. Make sure that the cable itself is not faulty by using a different cable, if possible.
c. Check the network connection.
3. Ensure that the print media that you are using meets specifications.
