New Way Epson Prevents Compatible Cartridges

The printer companies keep coming out with new ways to prevent refilling or using compatible cartridges. HP does it by putting an expiration date in the cartridges. But this is a double-edged sword. People have bought new, genuine HP cartridges only to have them rejected as being expired.

Epson is putting serial numbers in the chips of their new cartridges (T786, T220, T410, T288). The printer records the serial numbers of the cartridges used and will not allow the same serial number to be used again. This prevents refilling. However it also adds a level of difficulty in manufacturing compatibles. Until now, the companies have not had to place serial numbers on their chips. Now they have to come up with a method of creating a number which is 1) compliant with the valid serial numbers the printers are expecting see and 2) unique for every single cartridge even between different brands. Otherwise, if you buy cartridges made by two different manufacturers, you could wind up with repeating serial numbers. Fortunately, they appear to be cooperating with each other because we have not had an issue between the two brands we carry. Perhaps they are both getting their chips from the same manufacturer.
