Your printer says ”replace ink cartridge”?
If you have a inkjet printer, then you will no doubt you will have experienced this before. Your printer annoyingly reminds you switch over the cartridge , but you brush aside the message and keep printing. Sometime later (possibly days or even weeks), you find that the empty cartridge you were warned about is still printing! Is it a miracle, is there life after death, did I dream the message is the first place, am I losing the plot ? The answer to all of the above is NO.
Perhaps your machine doesn’t even give you that message , but simply stops printing when it reaches the decision you have had enough ink for the price you paid for the cartridge.
We had a little look in to this and found that many ink cartridges have up to half the amount of ink left in them, when they cease to work
What we learnt
We had a play (I mean tested) three of the top brands Canon, Epson and HP to see what we could find.
The quantity of ink left in the cartridges ranged dramatically from about 10% in a black epson ink cartridge to about 40% in a remanufactured Canon ink cartridge.
Our findings were as follows, as a general rule, there was more ink left in compatible / remanufactured ink cartridges than oem ink cartridges, this can be partially explained by stating that many compatible or remanufactured ink cartridges can and do contain a lot more ink than the genuine cartridges
It’s crucial to note that our results show the performance of a clutch of single printers, each paired with just one cartridge. Since OEMs and their aftermarket competitors sell loads of ink cartridges for a wide variety of printer models, you should purview our findings as a kind of snapshot at the way cartridges and printers work and deals with the leftover ink.
Why is so much ink left in the cartridge?
There are good reasons for not draining an ink cartridge completely, many inks, if they run dry, can cause crucial damage to the printer. You should always leave a small amount of ink left in the tank so that the printer never runs dry and becomes useless and worthless.
Experts would say that you are only discarding a few millilitres of ink and that printers are much more economical than they used to be. However many people have said very different experiences with ink cartridges. Judging from these findings, printer owners are probably throwing away a lot of usable ink. And that’s a problem, when you consider the environment and when you consider how expensive the printer ink actually is.
Caviar anyone?
If you work out the cost of ink per millilitre from an average HP cartridge for example, you will find that it is more expensive than Dom Perignon champagne or caviar (if it was sold per millilitre, not that I would know how it is sold. And I couldn’t do a comparison with cheese & onion crisp!).
We only tested black cartridges because otherwise it would get to complicated, not to say expensive, and we are not made of money.
Watch the Page Yield
Some retailers and manufacturers recommend that you make sure that they get the correct page yield (total number of pages produced with a single cartridge), rather than focusing on the amount of ink left unused in a cartridge that must be binned . This is the most veritable way to find out the life of a cartridge, rather than the amount of ink, or what might be left over. But manufacturers published page-yields don’t always tie up in reality. Plus page yields are quoted as 5% coverage of a page, this makes the whole process to complicated for the average consumer to look at, even if they did have the urge to do it.
We have never really heard a decent response to the question why so much ink remains in a ink cartridge, but the fact is you are paying for more ink than you will be able to use.
What can you do about it?
We believe, the best way to save money is to use compatible or remanufactured ink cartridges and not the original cartridges. The compatible cartridges are generally a lot cheaper and contain more ink. It is true that in many of the printers, you will not be able to use that extra ink. But either way, you have not spent as much on a compatible cartridge as you would on a original one.
Also the remanufactured cartridges are recycled, so you are helping the environment at the same time.
