What happened to HP printer ink page yields nowadays? Generally, there have been several ways to choose the size of the inkjet cartridge before you bought it. Most often there was the volume of ink in ml (milliliters) or sometimes fl (fluid ounces) printed on the box, cartridge or both. Sometimes there were page yields listed on the website of the company or listed at the retail level.

This information was decisive in distinguishing expensive cartridges from economical models. Till recently, a majority of that information could be taken at face value but last week, a valid question about the availability of OEM stated page yields was put forward in an accidental discovery.

First of all, I’d have to say that absolutely there is no exact way to predict how many pages you may eventually get from a particular ink cartridge. This is owing to the large quantities differences in printing material, surroundings, habits and during the time frame,when the cartridge is used, all of these variables were changing. According to this, I just can’t help calling these “tricks” on HP.

We found that there were no more ink volumes available on any the cartridges we looked up while searching for ink volume information on new cartridges from the website of HP. Luckily, those were not needed anymore because we had already collected OEM ink volumes and page yields on all the former printer cartridges as they had been announced in the old days.

The new versions, for example, the HP 60 black (CC640WN#140) and HP 901 (CC653AN#140) cartridge only showed “Cartridge yield: approx. 200 pages (indeed yield depends on printer and the way you use it)”.

A quick trip out to our own warehouse would turn out to be fruitless in finding the information we needed from the actual product’s box. Not any of the new OEM HP 60 boxes included the list of ink volumes and it is unusual if the page yield numbers were rounded to even 100 page increments just like “~200 pages”. I took an HP 74 OEM cartridge from the warehouse shelf, which was released a few months ago, it showed “HP 74 4.5 ml/0.15 fl oz” on the back of the box.

We just got another shipment, the HP 74 OEM cartridges so I had a look on the back of a new shipment of cartridges, it read “HP 74 ~200* pages”, but it seemed that the volume of ink had been removed. The HP74 now turns out to have 200 pages and I get the message that it has 4.5 ml of ink from the older box’s list.

Let’s assume that it is an honest evaluation because the HP74xl covers 18ml of ink and has listed page yield of 750 pages. Now that the new “standard” HP 60 black cartridges has listed 200-page yield, and it retails at the same price , could I confirm the correctness that it must have a 4.5 ml volume of ink? However, there is no way to get the answer.

I was wondering whether all of the previous HP cartridges have new information about their page yield now, so I looked up some older HP models at my will, what surprised me is that the list of page yields on Hp’s website had altered! I confirmed HP cartridges page yields form asapinkjets.com with Staples.com and all the links.

After checking the HP.com again, I discovered that the page yields had been changed, even all the other directions are not useful any longer. Here were some cases: C9351AN-HP 21Staples 150HP now N/A, C9352AN-HP 22Staples 140HP now 165 ,C9362WN-HP 92Staples 210HP now N/A, C9361WN-HP 93Staples 175HP now 220, C8765WN-HP 94Staples 450HP now 480.

Trying hard to find an illustration, I collected as much information as I can from the websites on each HP cartridges, I supposed that if HP transformed the print head on the cartridges, there may also be a change in the drop size of ink could explain the changes in the page yield.

Compared the known ink volume of each cartridges with the listed page yield of each cartridges which was supplied by HP, I put forward a pages per ml figure, then I tied in alike Pico liter drop sizes which means size of a single kind of ink’s drop formed by a single nozzle from diverse models, these models for some black and color ink cartridges had been announced over the last 10 years.

Though they are in the same size of PL drop, there are still enormous diversities in page yields /ml of ink among different HP cartridges models. Here are more details, color ink cartridges with a 5 PL drop varied from 21 to 68 pages per ml, while black inkjet cartridges with a 17 Pico Liter varied from 22 to 30 pages per ml.

Still and all, as time goes by, some advances in technology also have contributed to the total increase in pages /ml. However, the changes are too great to do something that I can just draw a conclusion: at best the manufacturer’s page yield information is incorrect while totally fabricated at worst. It seems that the Pico Liter drop size could also do nothing for page yield.

So what do you learn from all this above? Well, you may learn that it’s more difficult than before to work out how much you can get from your money. Page yield information is being opinionated increased or just rounded up, and absolute ink volume information isn’t being announced so it makes average consumer feel tougher to estimate the worth of an exact cartridge. Nonetheless, it makes it simpler to list untrue page yield information on the box ever since they take no responsibilities to understand those numbers.The pool of information is turning to be a little doubtful. HP should do something to make buyers beware.
