A smart chip that most manufacturers put on their cartridges is a curse for the do-it-yourself refiller. Their sole objective is to make the process to refill inkjet or toner cartridges more difficult by taking in the user into the belief that their empty cartridges are dead and cannot be re-used after refilling. Thanks to market demand and government involvement that put limits on the monopolization of the OEM cartridges. The truth is that smart chips are merely an inconvenience and there are techniques that can be utilized to reset smart chips and help reuse of run out cartridges for both laser and inkjet cartridges. Additionally, some manufacturers built in re-use options for their printers that allow the user to refill cartridges with resetting.

In the case of HP 564xl inkjet, replacing the cartridge chips and resetting computer chip makes refilling more successful. Resetting the computer chip says the ink cartridge is a real HP cartridge that was purchased at full price and not a refilled cartridge. You may wonder what the chip resetter does. Well, this small device tells the smart chip that the ink cartridge is a new one. Needless to say, the smart chip is fooled by the chip resetter that the empty cartridge the printer holds is new and certified as well. So, all that needs to be done is to remove the printer cartridge, refill it and reinstall it into the HP printer, and you are all set to go.
