Resolving printing problems

Printer shuts down unexpectedly

Check power and power connections

Make sure the printer is connected firmly to a functioning alternating current (AC) power outlet. See Printer specifications for voltage requirements.

All printer lights are blinking

A non-recoverable error has occurred

Reset the printer. See To reset the printer.

If the problem persists, contact HP. See Support and warranty.

Printer is not responding (nothing prints)

Check printer setup

See General troubleshooting tips.

Check the printhead initialization

When printheads are installed or replaced, the printer automatically prints two alignment pages to align the printheads. This process takes about eight minutes. You can print documents only after the automatic alignment pages have been printed.

Check the printer software installation

If the printer is turned off when printing, an alert message should appear on your computer screen; otherwise, the printer software might not be installed correctly. To resolve this, uninstall the software completely, and then reinstall the printer software. See Uninstalling the printer software.
