Abstract
A method for restoring an imaging cartridge chip, applicable in the technical field of imaging. In the process of restoring the imaging cartridge chip, a laser beam is used at least to unseal a location where a functional interface is on a storage device comprised in the imaging cartridge chip, or at least to scratch open or to drill open packaging material at the location where the functional interface is, then restore data is written into the storage device via the functional interface and a read/write interface. This results in the repair of the imaging cartridge chip.
