Program is easy to use, with the additional manual for reference. It allowed me to correct a corrupted EEPROM in the printer. All the .prn files are missing, so setting up the printer/scanner and the final print check are not possible. If you only want to reset the ink pad counter then there are cheaper/ free program available. Would give it a GOOD rating if missing files were included.

CLaI779ZViaHemp Gummies are a type of CBD-infused edible designed to provide the benefits of hemp, including relaxation, pain relief, and overall wellness. These gummies are part of a broader category of CBD products that are becoming increasingly popular for their convenience and ease of use. ViaHemp Gummies contain CBD (cannabidiol), a non-psychoactive compound found in hemp plants. CBD interacts with the body’s endocannabinoid system (ECS), which plays a role in regulating mood, sleep, pain, and immune responses. By interacting with ECS receptors, CBD helps to restore balance in the body, contributing to its therapeutic effects.

after only cleaning the printer (Canon G3400) three times in a short period, the waste counter was on 100% (almost new printer). tried the free tools which you can download to reset the counter, they all didn't work. Finally decided to buy the key here and didn't believe it would work. But it did, i can use my printer again and I am happy.
