When install a new chip my printer shows "Supply memory Error", what should I do?

Restore factory setting:

Try to press the green key of "Start" and the red key of "Cancel" at the same time, then turn on the power source, operate the action two times, finally change a new chip.

There is an error message in the memory of your printer. This circumstance is rare and particular: if you install our chip to another good printer it won't happen again. In one word, the root of the problem is the printer rather than the chip.

The root of the Problem:

The chip didn't touch well with the contact connection and the gap should face down.

The error message of the printer collided with the serial NO of our chip.
