Abstract
Embodiments of this application relate to the technical field of consumable chips, and provide a regeneration chip and a contact control method therefor. In this way, connection or disconnection between a printer connection contact and a native chip connection contact of the regeneration chip may be controlled, thereby avoiding problems of signal interference and collision that are caused because the regeneration chip and a native chip send signals to a printer at the same time. The regeneration chip comprises a printer connection contact, a native chip connection contact, and a switch signal end, where the native chip connection contact is connected to the printer connection contact via a switch circuit, the switch circuit is further connected to the switch signal end, and the switch circuit is configured to connect or disconnect the native chip connection contact to or from the printer connection contact under control of the switch signal end.
