Troubleshooting installation issues
Problems printing an alignment page
When printheads are installed or replaced, the printer automatically prints a few alignment pages to align the printheads. This process takes about 8 minutes, and the alignment pages may be discarded after they are printed. If the printer does not print the pages, try to start the alignment process manually (see To align the printheads).

Verify installation preliminaries
●Before installing software on a Windows computer, ensure all other programs are closed.
