Have you ever had your printer's software tell you
that your cartridge was out of ink well before the
cartridge was actually empty? Have you experienced
your printer refusing to print until you've replaced
the non-empty cartridge with a new one?
You're not alone. Consider this report from Recharger
magazine, published in 2003;
A recent lawsuit filed in a Texas District Court
accuses Epson of shortchanging users of its
printers, alleging that some models of the company’s
inkjet cartridges prematurely show that they are
empty. This blocks Epson printers from functioning
even though a substantial amount of ink remains in
the cartridge.
Based on independent tests, the lawsuit alleges that “10-30 percent of ink remained in Epson inkjet cartridges despite the fact that the Intellidge chip was blocking the printer from functioning.” According to the suit, several common questions that will form the basis of the case include: whether or not Epson cartridges with the Intellidge chip prematurely indicate that they are “empty” on customers' computers while there is still substantial ink remaining in the cartridge; whether or not the cartridges prematurely block Epson printers from functioning while there is substantial ink remaining in the cartridge; and whether or not the Intellidge chip's false indication that the inkjet cartridge is “empty” forced the plaintiff class to purchase replacement Epson inkjet cartridges prematurely. Some background facts cited in the lawsuit allege that the price of inkjet cartridges remains “relatively high” despite competition from generic cartridge manufacturers and recyclers and, as a result, printer companies earn more revenue annually from the sale of replacement inkjet cartridges than from the sale of actual inkjet printers. In the complaint, Harnes Keller LLP also alleges that Epson “actively and consistently discourages” the use of any replacement cartridges other than those manufactured by Epson. And this, from an online newsgroup for Canon
customers;
However, the mechanism the (Canon) iP4000 uses to report the ink levels of its cartridges needs some improvement. I've seen new users of the iP4000 gleefully reporting that after having printed many photos their iP4000 indicates the print cartridges are still full. These users are in for an unpleasant surprise: While I haven't seen this noted in the printer's documentation, Canon has informed me that the iP4000 doesn't update its display of remaining ink until about 80% of a cartridge's ink has been consumed (this applies to both the automatic and the manual updating systems). A Hewlett-Packard support technician offers this
partial explanation;
The printer recognizes that the cartridges were used and has no way to know the proper ink levels. The ink levels are stored in the printer, they do are not stored in the cartridges. If you move a cartridge from one printer to another the printer will disable ink level messaging since it has no way of telling the proper ink levels. This, in plain English, is what's happening.
There are no floats or other mechanical means for a printer to determine how much ink is left in a cartridge. The manufacturer programs the printer to know how many pages, at 5% coverage-an industry standard, a new cartridge should produce. For example, an HP #57 color cartridge is rated at 450 pages. The electronics on the cartridge reset the counter every time a new cartridge is installed. When the counter reaches 450, it will tell you that it's out of ink. Depending on what type of printing you're doing, this may be fairly accurate or wildly inaccurate. If your ink cartridge reports that it's empty well
before you think it should be, we can help you find
out just how much ink you really have left. Bring
your cartridge into the store and we'll weigh it for
you. We know the empty and full weights of all the
cartridges we service. By its weight, we can tell
you more accurately than software can whether or not
your cartridge is empty. (We cannot tell you how
much of each color is left in a color cartridge, but
we can tell if the cartridge is empty, full or
in-between.)
So why do printer manufacturers want to mislead you
into replacing ink cartridges before they are really
out of ink? Billions of reasons.
Spending in U.S. retail stores on toner and ink jet cartridges is forecast to jump 43 percent by 2007, to $26.3 billion, according to Cap Ventures. |

Whether you just got a new printer or have had your
printer for ages, chances are we can recycle your
cartridges to get you printing again for less than
you'd spend elsewhere. If you're thinking about
replacing your printer and need advice on which
model is right for you, give us a call and we'll
help as best we can.
