Solved!

Photosmart 7520 Black ink or photo black

HP Photosmart 7520
Microsoft Windows 10 (64-bit)

Thank you to Dragon-Fur and Bob_Headrick for their replies to my post.

 

I am thinking of buying refillable cartridges so am looking into CISS ink suppliers.

 

But first, I want to ensure I get the correct type of ink for my printer as there are plenty of horror stories out there of printers/printheads being ruined by cheap or poor quality inks.

 

So first, my printer is HP Photosmart 7520 All in one. I understand that the BLACK ink is PIGMENT based and the CYM and PHOTO BLACK are DYE BASED inks. Hopefully someone can confirm this is correct.

 

I believe that pigment based inks are used on the basis that they give a longer print life/do not fade as soon as dye based inks, or at least that was the traditional way of thinking.

 

(It seems it is not simply a case of buying either dye based inks or pigment based inks as there are different types of each, depending on the inkjet printer types/methods of printing. For example Epson dye based inks are not compatible with my HP.)

 

I appreciate that Dragon-Fur stated “Photo Black and Regular Black are not the same thing and are not interchangeable.” And I see that the cartridges are of different sizes and therefore not interchangeable. However, I wasn’t 100% certain whether he was simply referring to the cartridges or the ink type.

 

So forgive me if I am being a little obtuse, but if you can answer the following questions, it will clarify the picture for me.

 

My main query is this – is it essential for my printer to use pigment based black ink in the black cartridge?

 

Alternatively, what would happen if I used dye based black ink in the black cartridge?

 

Thank you.

Thanks Sandytechy20.

I see you are an HP employee so I must assume your answer is correct.

I seen read in two separate places that the PHOTO BLACK is dye based and the BLACK is pigment based.

see extract fro the forum below -

The black cartridge is pigment based, the color and photo inks are dye based.

Do you know if this was correct at the time?

If so when did HP change the BLACK to dye based?

 

Hope to accept your reply as 'SOLUTION' once you reply to this poating

 

Thanks Chris19481

Thanks again Sandytechy.

Brilliant reply; i followed the link and found confirmation so I should accept this as a solution (I will).

 

BUT it begs further questions - hope you can answer these too.

First, if both PHOTO BLACK and BLACK cartridges contain dye based ink, why bother to have two cartridges?

Is the ink in both cartridges identical? If not how are they different.

AND FINALLY!!!  Was the ink in the BLACK cartridge a pigment based ink when the printer was first on the market?

 

Thanks again.

I must address myself specifically to the answers given by Sandytechy20 for which I thank you.

Unfortunately you have supplied me with conflicting answers to my question. On 01.29.20 and 01.31.20 you advised that the photo black and black, are both dye based. On 02.03.20 you advised that photo black is dye based and black is pigment based.

 

You did not address the outstanding queries raised in my last posting.

@Chris19481 It seems that the tech went through the details and mentioned in the end/last post, that the printer you possess has a "difference in regular black cartridge and photo black cartridge." and these are the differences, so this is his final findings:

Photo black ink cartridge is dye basted:- Technical details

HP Black Original Ink Cartridge  is pigment based :- Click here

 

I hope that answers your query,
