For years compatible cartridges have been increasingly undermining Epson's market share of the replacement inkjet cartridge market. Print quality of most alternative inkjet cartridges is arguably every bit as good as compared to an Epson replacement cartridge and in comparative studies there is a perceptible or even a distinct improvement in colour vibrancy with some makes of Epson compatible inkjet printer
Epson began adding chips onto cartridges
quite a few years ago - named
The impression is given that the chips are "clever" and measure ink levels, however, they in fact do no more than add complication and act as a "control" over how many prints a user gets from a cartridge.
The use of the "Intellidge" chip system has been extended to all new Epson inkjet printers over that period to date. Indeed it looks as though Epson will not be manufacturing any new printers which do not use chips.
ABOUT THE EPSON INTELLIDGE CHIP SYSTEM
FACT (1) The chips
do not measure actual ink level(s) inside the cartridge
FACT (2) The chip simply sits on the cartridge · and when installed it is connected to circuitry inside the printer. Without a chip connected and without a chip which "indicates an ink level" · The printer will not function
FACT (3) The printer will function properly with non Epson chips
HOW DOES THE EPSON Intellidge
When a new cartridge is installed the chip registers "full" and therefore the Ink Level Monitor shows "full". During printing (or indeed cleaning cycles) the droplets of ink fired through the printhead are being counted · once the total number for the cartridge is reached the chip is "switched off" At that stage the printer can not be used to print and in normal circumstances an end user would instal a new cartridge.
RESETTER · REFILL SYSTEMS
We have Chip Resetters for five types of
Epson chips currently available. The pin layout on chips has varied over
the years first there were 7 Pin chips and then 9 Pin
chips were used on T711-4 and T801-6 cartridges in EPSON PRINTERS. These
earlier types were in a 4-3 layout and then a 5-4 layout.
