The printer has an automatic feature to clean the print head. Usually, there is a lot of ink (Probably melt with dust) in the area where the print head is cleaned Remove the 5 torx screw as shown in the picture Assuming the print head is now removed (Not shown on the picture), now gently tip the plastic plate and remove it

thank you for that information, there is a video on you tube too but not in English but he shows it pretty well. my cartridges are stuck in the docking area, so only need to get to there, hopefully the system will work afterwards.

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

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!

Hi John, Thanks for your detailed instructions. I went as far as removing the pump/gear assembly. But whatever I tried, I could not manage to take out the "print head cleaning carriage". A photo would help if you have. Thanks & Merci! Chris

The instructions were very good. The most difficult part, strangely, was getting the LCD panel clips out. Good work. Thanks!

Black is completely blocked. It was printing before I put in a new cartridge. I got as far as removing the top panel torque screw, but no matter what I do, I cannot get the LCD panel clips to budge to get at the last screw. It is impossible to release them all at the same time. Any advice appreciated. Thank you.

Hey Paul, the first time I did this I couldn’t get the LED panel off either. At that time I found there was enough flexibility in the cover to lever it up from the rear sufficiently to reach inside and remove the printhead. Not ideal, but do-able. The next time (today in fact) I realised that it was possible to reach a finger inside the carapace at the front and toggle the lower right hand clip holding the LED which, once released, made it easy to unclip the remaining clips. Much easier! However, having now done this twice, I have decided to buy a new printhead (on eBay, from China, US$15 with free shipping).

Good instructions, but after reassmbly, I get a message that there is a cartridge jam, and I can't get it to work properly again. My initial issue was that the black ink wasn't working (but had plenty of ink left), so I was trying to clean out the printer head. But now I have no way of knowing if that addressed the initial issue.

Carriage Jam results from failing to reposition the guide robbon between the sensor assembly on the print head cradle.

There are 2 black blocks at the top of the circuit board at the rear of the print head/cartridge cradle. The plastic guide ribbon needs to be between the two blocks.

having done all cleaning the printer is going through all the the motions and just returning a blank sheet even though it is printing the diagnostic sheet perfectly regards EJL

Thank you for your help. I am upset: HP clearly made it difficult for the users to fix their stuff. I mean: screw hidden behind a label, cables very difficult to put back etc etc This company do not respect the customers nor the environment.
