Solve problems checklist
If the printer is not correctly functioning, complete the steps (in the order given) in the following checklist. If
the printer fails a checklist step, follow the corresponding troubleshooting suggestions for that step. If a
checklist step resolves the problem, skip the remaining checklist items.
1. Make sure that the printer is set up correctly.
a. Press the power button to turn on the printer or to deactivate the Auto-O mode.
b. Check the power-cable connections.
c. Make sure that the line voltage is correct for the printer power conguration. See the label that is
on the printer for voltage requirements. If you are using a power strip and its voltage is not within
specications, plug the printer directly into the wall. If it is already plugged into the wall, try a
dierent outlet.
2. Check the cable connections.
a. Check the cable connection between the printer and the computer. Make sure that the connection
is secure.
b. Make sure that the cable itself is not faulty, by using a dierent cable if possible.
c. Check the network connection: Make sure that the network light is lit. The network light is next to
the network port on the back of the printer.
If the printer remains unable to connect to the network, uninstall and then reinstall the printer. If
the error persists, contact a network administrator.
3. Check to see if any messages appear on the control panel.
4. Make sure that the paper you are using meets specications.
5. Make sure that the paper is loaded correctly in the input tray.
6. Make sure that the printer software is installed correctly.
7. Verify that you have installed the printer driver for this printer, and that you are selecting this printer
from the list of available printers.
8. Print a conguration page.
a. 2-line control panels: On the printer control panel, press the OK button.
Touchscreen control panels: From the Home screen on the printer control panel, touch the Setup
button.
