Epson chip resetters work by overriding the chip and hence prevent the printer function from coming to a stop as long as at least some amount of ink is left. Chip resetters also enable the machine to recognize a refilled cartridge. This saves the users from the inconvenience of having to buy new Epson ink cartridges too frequently.
A particular kind of chip resetter can usually be used with few particular Epson printers, with which it is compatible. However a universal resetter can be used for all the various kinds of Epson printers. Examples of common Epson chip resetters are SK168 and YXD268, each of which can successfully be employed to reset a large variety of Epson printers.
Using the chip resetters is quite simple and easy a process. The Epson ink cartridge is lined up with the marks at the resetter base. The resetter pins are pressed firmly against the chip contacts on the cartridge for a few seconds. Blinking of red light indicates that the contact is good. When the green LED on the chip resetter turns on and starts blinking, it implies that the chip on the cartridge has been reset.
If the LED does not light up when the cartridge and chip resetter are pressed against each other, it means that there is no physical contact between the cartridge chip and the chip resetter. In order to resolve this situation, the chip resetter should be placed against the cartridge once again and pressed more firmly to ensure proper contact. Another probable reason due to which LED may not turn on can be the incompatibility of the chip resetter for the cartridge it is being used.
The LED light does not turn on if the cartridge chip is corrupt or contains corrupt data. In such a case, the chip should be replaced. Another cause can be the dead batteries of the chip resetter, which is not very likely to happen unless it has been used for thousands of times. If the chip resetter creates unfamiliar sounds, it means that its batteries have got loose. In order to resolve such a situation, the batteries should be reinstalled.

(From: Peter (firstname.lastname@example.org).)
Here are history/trivia. (I used to work at Xerox marking technology group, working on ink-jets and daisy printers.)
* Type 1 (or "push") ejects continuous stream (under pressure). The discovery goes back to Hertz (one who has the unit named after him) and theory is described in the book: The Theory of Sound, by John William Strutt, 3rd Baron Rayleigh.
Type 1 was commercialized first for printing postal labels and other similar applications. It was a big machine - 5x5x5 meters! Clumsy but fast. This was before laser printers. IBM published detailed (and definitive) research paper on this - circa 1985.
* Type 2 (or pull) uses electrostatic field to extract the drop. It was never commercialized.
* Type 3 (push-pull) or DOD is what we use in small printers now. Xerox put lot of money into developing this in the seventies, than (just when it achieved some 10 kHz (drops/second/nozzle) in the lab, (considered necessary minimum for viable printer) Japanese companies introduced first machines on the market. (I think first was NEC or Ricoh) and Xerox dropped the project. (Manufacturing people in Webster estimated that they can never produce it at profit, facing this competition.) Later, Xerox was using Sharp inkjet heads and printers, under Xerox label. Some research was then revived, (I suppose in cooperation with OEM supplier (Sharp).
