Troubleshooting

Wireless connection troubleshooting
Verify that the printer is within the range of the wireless network. For most networks, the printer must be within 30 m (100 ft) of the wireless access
point (wireless router). A USB cable might be required for temporary connection between the printer and the computer. To ensure that the wireless setup
information synchronizes correctly, do not connect the USB cable until prompted to do so.
Follow these steps to restore the network settings:
1. Remove the USB cable from the printer.
2. Follow one of these steps:
a. For a 2-line control panel printer: Press and hold the Wireless
LED start blinking simultaneously, release the Wireless
b. For a touchscreen control panel printer: Go to the Setup menu on your printer, select Network Setup, and then select Restore Defaults/Restore
Network Settings.
The printer will restore network default automatically and restart.
3. When the Ready LED is on, continue to install the software.
