Here’s a list of suggestions to help troubleshoot the issue with your printer:

1. Check to make sure the power cord and the USB cord are both plugged in and secured.
2. Clear any paper jams or unplug the power and USB cord, and replace any toner cartridges in need of replacement.
3. Check to make sure the printer isn’t set to fax or scan mode; to ensure that these settings are reset, try restarting the printer.
4. Check the size of the paper loaded in the main tray, and make sure it matches the size selector settings in the software.
5. If using labels or specialty photo paper, check your printer's user guide or contact the manufacturer for specific loading instructions.
6. Verify that the correct printer is selected in the software you are using to print.
