Step four: Install the duplex unit (HP Officejet Pro K550dtn and HP Officejet Pro K550dtwn)

The optional automatic two-sided printing accessory (duplex unit) allows you to print on both sides of a sheet of paper automatically. The duplex unit comes with the HP Officejet Pro K550dtn and K550dtwn printers, and is an optional accessory for the HP Officejet Pro K550 and K550dtn.

  1. On the back of the printer, if the rear access panel is installed, push the button on either side of the panel and remove the panel from the printer.

Step nine: Align the print cartridges

To ensure the best possible print quality, the printer initializes and aligns the printheads. At the beginning of the process, the Power light blinks and the printer prints a status page. At the end of the process, the printer prints the alignment pages (colored pages).

This process takes approximately 8 minutes.

If the alignment process does not print pages, complete the following steps.

  1. Check the following on the printer:

    • The power cord is firmly connected.

    • The printheads and ink cartridges are properly installed.

    • The rear-access panel (HP Officejet Pro K550) or the duplex unit (HP Officejet Pro K550dtn/K550dtwn) is installed.

  2. Turn off the printer and then turn it on again. The alignment pages should print.
