hp deskjet ink advantage 3525 - how to dismount the head step by step

Hello. Will anyone from the readers be so nice to show on the film how to pull the head from the ambulance, from taking the cover off the scanner. How to remove this cover? Urgency.
Maybe someone will write how to release the cover with the scanner from the hook ... ???

Hello
What purpose do you want to pull out the warhead?

That's all I have left. I hardly used the devices, only start-up once a month and only original inks. After loading a new set of inks, black does not print the printer and does not show any error. I bought a liquid that cleans the head and I have to dismantle it because when I drop the drops of the cleaner from the top, it stands like a wall, I think I'm sorry, I'm disappointed because I bought a set of original inks and loaded it even after the warranty. I am asking for precise instructions to understand how to unhook the latch that holds the head then I think I can handle it. I will not give it to the repair because I have already spent enough and I will say goodbye to hp if nothing will help. This is without printing anything after each switch and trying to print disappears black ink, I see the ink level in the printer.

This is a standard problem in this printer repeatedly on the forums and in this case, pulling out the head and soaking it in the cleaning chemistry will probably not help. It is normal for a drop of liquid to stand on top.
Personally, I always put a syringe with a tube that fits into the ink holder in the head and injects a little under pressure. Such a procedure always helps me.

However, if you want to pull out the heads you must:
- dismantle the plastic (the picture is brown with you probably black)
- attach 2 springs that are on the back of the head
- remove the heads and unhook the 2 tapes that are from the back of the head (1 wide, 1 narrow)

In this video it is shown how to dismantle the head, it applies to a different model but from 3min 45s is the same as you

Servicing this type of HP printer I know that your problem is not a clogged head for black. The problem concerns the clogged docking station, i.e. those elements on the right side of the printer where the ambulance with the head and inks is parked. I do not think you can deal with the problem yourself.
If you want to save equipment to use your inks, you will have to use a service technician. If you have a problem with finding the right service technician in your place of residence then write to me at WUT I will help.

Hello, I have the same problem. My hp model 3525 printer does not print in black.
What solutions did you use? Warm water cleaning did not work.
greetings

Head cleaning is unlikely to help.
As the previous speaker wrote, the pump mechanism should be disassembled (it is held on 2 screws) and the hoses should be unblocked.
Personally, I also disassemble the pump to make sure that there is not a gram of dried ink in the hoses.
It is also important to check the connector (it includes 8 hoses)

If you can upload photos of what you cleaned

I have already assembled the printer, when I will disassemble again I will take photos.
I cleaned it like in the movie, under the inks and in the place where they move. The bottom, when there is the "base" of the carcass, I also cleaned it because it was dirty. I am still trying to find some information on this.
Is it easy to disassemble the vials? Without downloading tapes?
Clean them, for example with a syringe or normally under the tap?

I confirm, it is best to unblock the head with a special liquid without removing it. Preferably a syringe with a tip that matches the strainer in the ambulance. Put a piece of folded paper towel under the head. After injecting the liquid (5-10ml), the ink will flow from the head onto the towel and it is best to let the head lie on the wet towel for a few hours. The fluid should enter the head without resistance. If you feel a lot of resistance, it means that the head is very seized. As after 2-3 such attempts to unblock it, it will still not give black on a piece of paper, you can remove the head and soak it in this liquid for several hours. Only before reinstalling, let the head dry, paying attention to the electronics so that it is not damp somewhere, because it is a small short-circuit and the head is over.

Gentlemen, please.
In 99% of cases, the problem is not the head but the ink suction station.

To dismantle stations:
1 remove the rail on which the ambulance rides (screws marked in red)
2 disassemble the station (screws marked in blue, one is on the back in the very corner)
When removing the station, watch out for the gears because if you tilt it to the left, 2 may fall off.

Thanks a lot for the advice. Tomorrow I will pick it up from the morning, as soon as I buy a syringe and liquid. What kind of liquid is it supposed to be? Earlier you wrote something about the liquid from the W5 lid to the windows. Such?
Instructions for disassembling the station and colors apply to the video from the link or earlier photos?

I already put a photo in a previous message.

For washing, you only need a syringe and good warm water. In order to clear the cables thoroughly, the ink suction station should be removed from the printer and disassembled into its first parts.

I do not discuss this issue of the docking station because I admit I never did. There is actually a place for waste under the station, which can take on the consistency of jelly over time and if you accumulate a lot of it and leave it for some time, the head will be rather blocked. I had printers with clogged heads in the service many times, they printed some colors and black did not print at all or at all, and always clearing the head solved the problem. But since you are sure it only helps with 1% of these cases, then I must have had some statistically incorrect cases.

What I call after the websites, everyone only mentions the head. I gave it to one magician to get this head overcome, but it still doesn't print in black.
Will someone recommend a website in Malopolskie? Krakow and its surroundings?
If I do not find a worthy service, I will have to do it myself ...

With this 99% of cases it may be an exaggeration, but I say the vast majority. He only writes about 655 ink models

As I have already mentioned, I have worked on the topic many times.
I left many printers aside because of ignorance, because if they started printing black after cleaning the head, then after a few / a dozen or so prints, black was missing again.

Last week I was making 2 pieces that stood for over a year. 3525 and 4625
The website found clogged heads, deleted customers, and there was no effect.
I disassembled the suction pumps, cleaned the hoses, cleaned the heads (after a year of non-printing they were due), cleaned the absorbers and the printers print correctly.

It is also worth noting that the problem usually occurs when we rarely print (the ink has time to dry) and as someone mentioned on the forum, black is pigmented and dries much faster than colors

Cool! I repeated the operation and success.
There were piles everywhere in the black ink absorber. They looked like black plasticine. The color hoses have been rinsed. The black tubing was so dry that the liquid could not be blocked. Stuffing with a straightened paperclip helped.
It's good to take everything out of the printer and take it apart. Everything will be different. Rather, the hoses need to be removed from the pump.
The felt on the right (ink scrap space) was packed. I didn't have a replacement, so I rinsed well, dried it and put it back in.
Thanks for the tips
