Replace Printhead HP Smart Tank Plus 570

[Woidmonstar]

Hi, 

I´m trying to replace the black printhead in my Smart Tank Plus 570 printer. After some research I could find, that many more persons have the same problem!

I have no errors or error messages! But I have extremely poor print quality with black!

The printhead cleaning says in the end to replace the printhead! But does not offer to start the process!

I also found some indications to contact HP Support in that case. But my warranty exceeded! How convenient!

So now I have to pay 25€ for somebody to tell me, that I cannot change the printhead when its necesarry because 

the printer, event though it itself recomends to change the printhead, does not let me change it because the is no error message?

Please send instructions how to force the printhead change and please update the printer firmware with this incredibly important function. If there is no way to do that, then I have a big pile of junk in my office that cost over 300€!

Thanks in advance

Hi @Betty0610

Thank you for your reply. 

Unfortunately the instructions in the link you send me do not help me at all. 

I already found that page and have a problem with following statement:

"Why does the carriage not move when I open the printhead access door?

The carriage only moves if the printer is in a printhead error state. If the carriage does not move to the center of the printer when you open the printhead access door, the printheads do not need to be replaced. Replace printheads only when instructed to by error messages on the printer software, control panel, or HP Smart app."

I have very bad print quality with black color and already cleaned the printheads arount 30 times. I also tried to align the printheads many times, but because of the poor print quality of the black color the alignment page ist never recognized. 

So I need a way, how to force the printer to put the printhead tray in the center of the printer so that I can replace the printheads. 

The possibility of replacing the printhead should be the responsibility of the owner of the printer and not restricted by the necessity of some error message. 

My printers printhead is damaged! My printer does not recognize it. 

So how can I solve the problem?

Hi Betty0610,

thank you for your reply. 

Unfortunately I´m not able to contact the support, because my printer is already out of warranty. 

Does that mean that I have to throw it away and buy a new one?

Or is there really no way to replace the printhead without an error?

You can take it to a service center in your area too.

Also, try this: 

Reset the product

• With the printer turned on, disconnect the power cord from the rear of the printer.
• Unplug the power cord from the wall outlet.
• Wait at least 60 seconds.
• Plug the power cord back into the wall outlet.
• Reconnect the power cord to the printer.
• Turn the printer on. HP recommends plugging the printer directly into a wall outlet.

Also, try connecting the Printer to a different wall outlet directly.

Let me know if this helps.

Hi Betty0610,

thank you for your message. 

I don´t think bringing my printer to a service center is going to help.

As mentioned before, the printhead has to be changed but my printer refuses to let

me do that. 

About the product reset, I already found these instructions and tried what happens. 

As expexted, nothing happened. 

In the moment I disconnected the power cord, the printer turned off. Several minutes 

later I reconnected the power cord and the printer turned back on. 

No reset, no access to the printhead. 

Also my question as an electrical engineer: what do you expext to happen, when I connect

the printer to a different wall outlet? 

The electricity stays the same. Same voltage. Same current. I do not understand the 

meaning and purpose of this hint.

I should add, that the printer uses a simple power cord without any electronics. The transformer

is integrated in the printer. 

I´d like to repeat my question: is there a way (some trick, button combination, sub menu, software, procedure) to

force the printer to leave the printhead bay in the center so I can change the printhead?

Heres how I finally did it.  Unplug the power from the printer while it is printing.  Once you do that the print head holder will freely slide and you can move it manually.  From there remove the printhead you want to replace.  Plug the printer back in and it will give a printhead error allowing you to install the new head.

Hope this helps.

Hi @Wjstone,

thank you for your support. 

Actually, I was talking exactly about the exact same procedure with a coleague a couple days ago.

But I refused to do it yet, because I believed that HP has to have implemented some "simpler" and

less bruteforce way to do that. But they seem to be unwilling to communicate their solution unless

you pay them for the "support".

Thanks again, I´ll try that and if something interesting happens or anything goes wrong, I´ll be back again.
