Push the clips at the rear of the LCD panel and pull the LCD panel outwards at the same time. The clips can be felt, but not seen underneath the plastic on which the HP label is visible in the middle picture. A fourth picture would help here.

Remove the 2 remaining torx screws hidden by the LCD panel

Remove the print head by pulling on the ribbons. These are delicate and easily damaged if attempting to clean with alcohol.

When inserting the print head after cleaning or replacing, make sure the horizontal plastic ribbon is between the plastic guides, as shown in the last picture. Getting this wrong may cause the print head to jam when you put the power back on at the end.

If you didn't put gloves yet, it is time to do it !

A l'étape 3, je n'arrive pas à retirer l'écran LCD. quand on me dit de pousser les deux clips à l'arrière, je ne vois les pas. tout semble solide et j'ai peur de casser quelque chose en forçant. comment franchir cette étape?
J'ai aussi eu un peu de difficulté à enlever l'écran LCD. Il ne faut pas hésiter à tirer dessus. Quand un clip est enlevé, les autres viennent plus facilement

Bonjour : très bon tutoriel, mais ..., manquent des précisions ; Etape 2 : comment est fixée et se démonte cette charnière-glissière ? Etape 3 : MISSION IMPOSSIBLE pour le démontage de l'écran LCD ! combien de clips ? à quoi ressemblent-ils ? comment faut-il agir sur ces clips, "à tâtons et en aveugle" ? etc ... ; je n'ai pas réussi à franchir cette étape qui demande des explications supplémentaires ... Merci : MJL

J'ai étais ravie d'avoir ce tutoriel entre les mains car j'avais de gros problèmes et la tout est très bien détaillé en image c'est parfait même les références pour les pièces à changer d'indiquer c'est très bien
The print head cleaning system carriage can be completely removed. Need to push the carriage to back of printer. Remove screw in back right corner, next to the black cylindrical pump with rubber hoses, and another in the gear assembly that runs this pump. Then wiggle and remove this pump/gear assembly. Now the carriage can be moved forward on the track till a slot allows getting past a small metal shaft and a gear. Now you can clean it in the sink with hot water. Be careful to put the two springs back on this carriage before putting it back into the printer.
And be sure all the tubing will freely flow water, or the pumping action will not work!
