Yes, most ink cartridges have chips (Smart Chips) on them, but Jerry’s coffee cup analogy and understanding of the HP 940/940XL cartridge and its chip is somewhat incorrect and misleading. I must respond in an attempt to clarify the actual number and educate the consumer.
Using Jerry’s coffee cup analogy, I will try to breakdown the cost, and describe the chip, ink level reset, and even Adaptive Ink’s ink quality.
Cost
You would like 4 cups of coffee. You order and pay for the 4 cups upfront, at a discounted price than is 75% less than if you purchased the 4 cups one at a time. However, you don’t want your coffee to get cold while you are drinking it, so you ask the waiter to initially bring you 1 cup. Then, very discreetly, the waiter keeps your cup filled as you are drinking it (without
interrupting you), until you have finished the entire 4 cups you originally ordered. And when you are ready for 4 more cups in the future, you repeat the process, prepaying for 4 cups once again at the deeply discounted price.
In a similar fashion to the continuously refilled coffee cup mentioned above (for grins, let’s call it a “CRCC”), there are 400 milliliters (400mL) total ink volume in an Adaptive Ink Mini-Pro CISS, as compared to 97mL total ink volume (16mL each color & 49mL black) in a set of HP 940XL OEM cartridges. The cost of an Adaptive Ink Mini-Pro CISS on the website is $114.95
and a set of 940XL cartridges can cost between $95.00 (Amazon) and $131.00 (HP store). This means that, through Adaptive Ink’s Mini-Pro CISS, you receive four times the volume of ink for approximately the same cost as a single OEM
cartridge set. This saves you at least 75% on your ink costs. And with the Pro-Series CISSs Adaptive Ink sells, the savings is even greater!
Chip
Jerry is correct that his HP 940 cartridge chips are now part of his purchased Adaptive Ink CISS and his system is transferring the ink from the external ink reservoirs (protected, sealed ink bags) to the cartridges, and to the print heads. Jerry’s printer’s software is telling him there is 70% ink remaining. However, Jerry (like many consumers) is misinterpreting what this “estimated ink level” is displaying. The chip has no way of knowing how much ink is actually in the cartridges … and I can prove it.
Here’s the proof: (I challenge Jerry, and anyone to do this simple experiment.)
- Take two of the same 940 or 940XL cartridges of the same color: one near empty (make sure the black rubber bladder on the cartridge has NOT sucked in, and note the ink level), and one brand new cartridge.
- With a marker, put an “X” on the near empty one (in two places, on the cartridge shell and on the bottom).
- Cut the cartridge labels and unsnap the bottoms from the two cartridges.
- Now swap the bottoms to the alternate cartridges, by snapping the shells and bottoms together.
- Place the full cartridge (without “X”) and the bottom (with “X”) in your printer.
Result: The “full cartridge” reads the same level as the near empty one.
6. Remove the previous cartridge and place the near empty cartridge (with “X”) and the bottom
(without “X”) in your printer.
Result: The near empty cartridge now reads full!
Conclusion: The chip DOES NOT monitor the ink level inside the cartridges. All the chip does is count down to zero and reports this counting down to the printer’s software. Using the ISO/IEC 24711 standard the “estimated” ink volume is displayed. The ink level display even says, and I quote: “Estimated ink level, actual levels may vary.”
Printer manufacturers used to be able to disable printing when their Smart Chips calculated the cartridge was “empty”. I’m sure many of you have seen this in the past. You took out the cartridge only to discover that you could still feel ink inside the cartridge.
Next, third-party manufacturer’s started making Auto-resettable chips known as ARC chips. A few years ago, the printer
manufacturers lost a class-action lawsuit that now prevents them from disabling printers when they “estimate” the cartridge is empty. The HP series 8000, 8500, and 8500a series of printers have Smart Chips that DO NOT expire, and as far as
anyone can predict never will. Since they do not expire, there is no incentive for third-party ARC chip manufactures to make one for these series of printers.
Ink Level Reset
Since there are no ARC chips for the 940/940XL cartridges, and the Smart Chips cannot be reset using a chip resetter, the ink levels on your printer display(s) will not “reset”, whether you choose to refill the ink cartridge or use an Adaptive Ink CISS. The only time the ink level WILL reset, is when you put in a brand new OEM cartridge. However, as we have calculated above, it
is less expensive using an Adaptive Ink CISS than purchasing OEM cartridges.
Adaptive Ink’s Ink Quality
Adaptive Ink uses OEM-Equivalent inks that are produced by a USA leader in specialty ink technology that is a leading supplier to the major OEM inkjet printer market.
Troubleshooting for HP 8500/8500a Printers
When the smart chip countdown begins to get low, you will see the following messages as the printer’s software estimates each cartridge is running low and depleted on ink:
Warming Up… (First message that scrolls across the display screen)
“The original HP ink in the following cartridge has been depleted: Color [X]. Information about ink levels will not be available. Press ► for more information.”
- Press the forward arrow (►) to the right of the OK button.
Warming Up… (Second message that scrolls across the display screen)
“Printer failure or damage attributed to the use of non-HP or refilled ink cartridge will not be covered under warranty. Replace ink cartridge or press OK to continue.”
Note: The ink level graphic on the printer’s display or the software ink level graphic are “Estimated ink levels. Actual levels may vary.” The symbol or character above each ink level represents:
- A check mark (√) = The ink level is estimated above 10% remaining.
- An exclamation mark (!) = The ink level is estimated below 10% remaining.
- A Red Box with an X, or a Question mark (?) = The cartridge ink pump hassucked-in (ink is completely depleted).
The Ink level bar is the remaining smart chip countdown graphically estimating the ink level of its cartridge.
How do I (actually we) know all this…
WE ARE Adaptive Ink.
To Jerry’s point of Adaptive Ink “not knowing or not telling” the answer to his question, we ask and direct all customers to view our website with our VERY extensive
FAQ page. (The FAQ page was initially live circa June 2010). While only Jerry can know what he personally considers to be ethical, we can assure you we have thousands of customers in tens of countries that are very satisfied with our products and our service. I am sure you will concede that we are far from the only business on the planet to use a voicemail service, in order to take phone messages while on the factory floor. However, our customers (and Jerry, we include you in this) actually have to leave a voicemail message as requested in order for us to know that they have called and what they are calling about. (We think this is a reasonable request, don’t you?) Add to this that we are saving our customers at least 75% of their consumable ink costs, and you can see why most people are very eager to do business with us. We may not be perfect all the time, but who is? Rest assured that we are always striving to provide the best current product line (and future products in development) for the consumer who we agree IS being exploited by the OEM ink price.
So in the end Jerry is advising you, the consumer, to purchase ink that is at least 75% more expensive, simply to punish Adaptive Ink for not answering a question to his satisfaction or perhaps level of understanding … a question that was already responded to in detail on our website at the time. I don’t know about you, but as a business person I don’t allow personal feelings to sway my opinion enough to pay 75% more for an item. You, the consumer reading this, simply must decide for yourself if buying ink is a business matter for you, or a way to participate in Jerry’s personal vendetta. Adaptive Ink has confidence that you will make the right decision.
