The nice thing about the SK168 is that it has feedback and replaceable batteries. When a reset
is successful, the green LED will flash. The batteries (3) are good
for thousands of resets and they are easily replaced.
The removable adapter (shown in above photo) is for resetting the thin C80/2200 type
cartridges. For the other type carts, this metal piece is not used.
The chips are reset without changing the Epson identification on the chip. The printers can
not detect that an external chip resetter was used. There is no limit to the number of
times a chip can be reset.
When you are attempting to do a reset, if the Green LED does not flash, this is an indication
that the chip you are trying to reset is either corrupted or damaged. The flashing of the
LED is feedback to you that a reset of the chip was successful.
If you hear a rattle inside the SK168, this means the batteries have come loose. The unit
will not work with the batteries loose. Take it apart and reinstall the batteries.
