What leads to the need for resetting a chip?

Epson cartridges have a memory chip that counts how many pages are printed and uses this to estimate the ink level. When a cartridge is refilled, the chip still remembers the old page count, so the ink level shown on the printer may be wrong. If the page limit is reached, the printer may stop printing even if there is still ink inside.

A chip resetter fixes this by resetting the page count to zero, allowing the refilled cartridge to work normally again.

What is a chip resetter?

It is a plastic device with several pins. These pins must line up with the pins on your cartridge, which are located on the bottom or along the side of the cartridge.

For cartridges that can be refilled and have a resettable chip, follow these steps to refill them:

Search online for the right chip reset tool for your cartridge. For example, look up “Epson cartridge chip reset tool” and include your exact printer model (like Epson SureColor P5000 or P5070).
When your printer says the ink is low, reset the cartridge before refilling it so the printer will recognize it as full.
- Remove the cartridge.
- Line up the pins on the cartridge chip with the pins on the reset tool.
- Press the cartridge down firmly for a few seconds.
- A red light will show first to confirm a connection.
- Then a green light will show to tell you the reset is complete.
After the chip is reset, refill the cartridges.

Note

There is no universal chip resetter. Most cartridges use either 7-pin or 9-pin chip layouts. Before purchasing, visually compare the pin layout on the reset tool with the pins on the bottom of your cartridge.
Only reset (and refill) a cartridge when it still has at least 15% ink remaining.
The reset tool is compatible with original Epson cartridges. If you are using a non-genuine or third-party compatible cartridge, please check with the supplier or confirm in advance that your specific cartridge model has a resettable chip. Not all compatible cartridges can be reset.
