HP DeskJet GT 5810, 5820 Printers - Replacing Printheads

note:

Priming cannot begin until new tri-color and black printheads are installed at the same time into the printer. An E-8 error occurs if only one new printhead is installed in the printer.

1. Turn on the printer.
2. Make sure paper is loaded in the printer.
3. Make sure that all ink levels are above the minimum fill line.
   Figure : Example of ink at minimum fill line

   
4. Close the output tray extender, and then rotate the output tray left to stow it in the printer.
