Epson WF-7820 Chip Resetter: A Guide to Simulating Cartridge-Changing Events

When you're faced with an error message on your Epson WF-7820 printer, it can be frustrating and costly if you don't know how to fix it. One common issue is when the printer displays a 'cartridge cannot be detected' error message after refilling or replacing a cartridge. This is because the printer's OEM chip has stopped functioning properly.

To resolve this issue, we need to simulate a cartridge-changing event. Simply remove the cartridge and put it back in place. This will confuse the printer and display an error message stating that the following cartridge cannot be detected. Once you've done this, the printer will reset its ink level and display full tank levels again.

However, this method is not without its limitations. Unlike a resetter device, which can force-write 'Page=0' to the Epson's OEM chip, we cannot control the reset time when using this method. The chip will continue to roll back to zero after reaching maximum capacity.

To avoid reducing our chances of resetting the ink level, it's essential to perform this action before the ink level drops below 15%. By doing so, we can maintain control over the reset time and ensure that our printer continues to function properly.

A resetter device is designed specifically for this purpose. It writes 'Page=0' forcefully to the Epson's OEM chip, allowing us to reset the page count and continue printing without any issues. There are two traditional methods of performing this action: one using a resetter device and another without it.

Our goal when refilling our cartridges is to put the printed page back to zero after refill, so the printer will read a full tank. Unfortunately, many people who refill their cartridges find that their printer still thinks the cartridge is low on ink or empty. This is because Epson printers use a computer chip on the cartridge to track how many pages have been printed, rather than measuring the amount of ink left in the cartridge.

In conclusion, simulating a cartridge-changing event can be an effective way to reset your Epson WF-7820 printer's ink level after refilling or replacing a cartridge. However, it's essential to perform this action before the ink level drops below 15% and use a resetter device if possible to maintain control over the reset time.
