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 20 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.
