The original website reports that Epson was already using new Firmware
that prevented this in the 1280 back in 2001. Last update in 2001.

assign a number to the cartridge and save both this number and ink
counter to cartridge chip and the internal battery backuped memory. At
the start of every printing and power on/off it checks this number if
it is not the same, it starts ink charging cycle which means waste of
ink. They also sense removal of cartridge but this is easy to disable
by shorting 2 shunted pins of the cartridge to the ground.
