Chip and replaceable unit of image forming apparatus
Abstract:
A chip used for a replaceable unit of an image forming apparatus includes a storage unit configured to store related parameters of the replaceable unit, a plurality of electrical contacts, and an impedance branch. The image forming apparatus is provided with an electrical contact terminal. An electrical contact is capable of electrically connecting to the electrical contact terminal. One end of the impedance branch is connected to at least one of the plurality of electrical contacts for achieving a detection of contact reliability between the at least one of the plurality of electrical contacts connected to the impedance branch and the electrical contact terminal of the image forming apparatus.
