Troubleshooting installation issues

Problems printing alignment page

When new printheads are installed, the printer automatically prints two alignment pages to align the printheads. This process takes about eight minutes. Do not open any covers or push any buttons until the alignment pages have printed. The alignment pages may be discarded after they are printed. If the printer does not print the pages, then see General troubleshooting tips or align the printheads manually (see To align the printheads).
