HP Officejet Pro K550 Printer - Manual (Page 58)

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 ).
