Check the print queue
A print job might be stuck in the print queue. To fix, open the print queue, cancel the
printing of all documents in the queue, and then reboot the computer. After the
computer reboots, try printing again. See your operating system help for information
on opening the print queue and canceling print jobs.
Check the device setup

Troubleshooting tips and resources .
Check the printhead initialization
When printheads are installed or replaced, the device automatically prints a few
alignment pages to align the printheads. This process takes about 12 minutes. Until
this process is complete, only the automatic alignment pages can be printed.
Check the device software installation
If the device is turned off when printing, an alert message should appear on your
computer screen; otherwise, the device software might not be installed correctly. To
resolve this, uninstall the software completely, and then reinstall the device software.
For more information, see
Uninstall and reinstall the software .
Check the cable connections
Make sure both ends of the USB cable are secure.
