    Cette démonstration est particulièrement mauvaise. Sur ma 5520, il n’y a pas moyen d’accéder aux “clips” sans casser les 2 supports de l’afficheur LCD. Plutôt que de risquer de casser quoi que ce soit et d’aggraver la situation, j’arrête là avant d’obtenir une info complémentaire sur le démontage PROPRE du LCD.

    • Now the cover can be removed and expose the inner workings of the printer.

  5. Remove the springs that maintain the print head. Remove the print head by pulling on the ribbons. In case you want to replace the print head, the spare part reference is: CN688A

    • 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.

    Great instructions to this stage. Underside of print head can be washed under warm running water if you keep the end with the electronics dry.

    It can also be interesting to gently clean the thin plastic band.

  6. 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.

    Followed instructions …very clear! Now I am getting cartridge jam message and cannot get rid of it. Whirring noise before message comes up.

    OMG the print head cleaning area was so full of old ink. It really needed removing and soaking but could not see how to remove it under the sea of old ink so had to mop the worst off with paper towel and reassemble. Works OK now.

    sjgroom - 回复

    Instructions work well. Fortunately, the ink muck is water soluble. After cleaning, (cleaning carriage as well as the printhead) I continue having No Black Ink delivered during printhead cleaning routine or when I try to print using “Black Ink Only”! Next option is print head replacement or a trip to Best Buy to buy a Win10 printer.

    Thank you,

    Comment pouvez-vous écrire que le chariot est maintenant propre alors que vous n’avez pas indiqué comment enlever l’encre et la poussière collée? Ce chariot peut-il être démonté? Si oui, comment afin de le nettoyer? Merci.

    JOUFFROY - 回复

    Merci beaucoup, très bien expliqué. Tout est propre, malheureusement la cartouche noire ne fonctionne pas.

    Je suis allée dans les paramètres de l’imprimante “type de papier” , qualité d’impression” ,”plus foncé/plus clair” etc.. je dois au minimum choisir “qualité optimun et “le plus foncé” pour avoir un résultat gris pâle.

    Par contre si je choisis qualité “photo” j’obtiens une impression noire et correcte…

    There is a little ink pump which removes ink to the right side and soaks a sponge if that sponge is full of ink that starts to sip everywhere. You can remove the sponge and rince it then dry it.

    Cad Axe - 回复

    When the instructions state “remove the five torq screws”, the one on the top right of the photo should not be removed (so, remove only four). It serves only to keep two pieces of plastic together and does not hold the plate in the machine.

    Nach dem zusammensetzen habe ich ein Problem mit dem Schlitten. Beim Start direkt aus der Parkposition heraus knallt es und ich bekomme immer die Fehlermeldung “Patronenwagen blockiert”. Beim manuellen Schieben merkt man auch, dass irgendwo ein kleiner Widerstand ist. Was kann ich beim Zusammensetzen falsch gemacht haben?

    Marco Trampe - 回复

    After I cleaned the printhead many times without more succes then before, I replaced it now with a new one. But STILL it is not printing black!

    I tried 4 new black cartridges already. The other colors work fine, but just not black. I have the newest firmware running. Has anyone another idea?

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!

John Taft - 回复

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

Christian RAPHALEN -

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

joespitzak - 回复

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.

Julie O'Meara - 回复

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.

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.

Instructions were good until this point: “Remove the 2 remaining torx screws hidden by the LCD panel…See where are clips (Blue arrows).” No explanation on how to remove the LCD panel and no blue arrows in the diagram pointing out clips. Did the author take a doobie break? Thanks to the comments, I figured it out. However, pulling the ribbons off the print head broke one of the plastic plugs off the printhead, forcing me to order a new one. With Mr. HP in pieces and doubts about a new printhead fixing this boat anchor, I’m strongly tempted to slam dunk it into my trash receptacle and be done. Thanks HP for another stunning piece of crap.

Merci pour ce tutoriel ! Mon imprimante avait vraiment besoin d’un petit nettoyage, il y avait de l’encre partout !

J’ai fait attention lorsque j’ai remis tout en place, et pourtant au redemarrage, l’imprimante me signale un blocage charriot (alors que le charriot se déplace librement sans problème à la main et grace aux moteurs). Auriez-vous une idée ? Serait-ce le ruban horizontal de la tête d’impression qui aurait été endommagé ?

Merci beaucoup !

Does this mean we leave the plastic panel out ?

It just says remove the plastic panel, and the printhead carriage is now clean !!

To people struggling with the LED panel; I lift the panel as i’m trying to push the catch in the back. This seems to make it easier to get the catch back.

I removed the print head cleaning carriage assembly that slides fore and aft on the right side of my hp 5520 printer. After cleaning the plugged black ink tube that is attached to it, I’m ready to install it. PROBLEM: There are 2 springs on this unit…one on the side which I reconnected. The other is a smaller (weaker) spring that goes on the bottom of the unit. I see where the one end of the spring attaches but cannot figure out where to connect the other end. Any help would be greatly appreciated.

Ça fonctionne aussi très bien pour une HP Photosmart 5515.

Paul - 回复

Just reassembled my 5520 after installing a new printhead; unfortunately I am now receiving the message that “the cartridge access door is open” and it is not. The mechanical part of the system is in working order so it seems that the sensor itself has failed. Is there a fix for this? Yes, I have done a hard reboot multiple times but still receive the error. Help please.

Bill Fleming - 回复

Did you find where to put it? The same part appeared in my sink as I cleaned the larger panel - it goes somewhere touching that panel, I’m sure, but it is not obvious where! It would be helpful if the generally very clear instructions warned about this and showed where this rogue part fits in.
