Phaser 3100 MFP resetting

[Tamz]

Hi, I just bought a secondhand xerox phaser 3100 MFP machine and my printing page will soon reach to 4000pg.

In case it will reached to 4000 printed page how do I reset it? Do i need to buy a reset chip or just buy only the ink cartridge and it will automatically reset by itself? Thanks in advance for your comments.

Change it when it runs empty,not at exactly 4000 impressions, the chip is in the cartridge, not seperate.
