When a user replaces the maintenance box with a new official unit, the printer recognizes the "new" status code and resets its internal counter. The resetter mimics this process. By physically connecting the resetter to the chip contacts on the old maintenance box, the device overwrites the data, resetting the status from "Full" back to "New." This tricks the Epson L6170 into believing a brand-new unit has been installed, allowing the printer to resume operation immediately.
If you only replace the box, the counter stays at 100%. Epson’s official solution is that you must take the printer to an authorized service center to have them reset it for $50-80 per visit. That’s why learning to reset yourself pays off in 1-2 uses. maintenance box resetter for epson l6170
