HP LJ P3005 -- Engine Test

The engine test pushbutton is well hidden. Remove the right side cover by forcing it rearward. About 1 1/2" below the bottom-front corner of the fan grille there's a small round hole. Poke in there to operate the switch.

Press and release for a single print. If you hold down the switch, the test will print pages continuously until the switch is released.

The test print is horizontal lines.
