Abstract:
Disclosed are a regenerative chip of printing supplies, and a contact control method therefor. The regenerative chip comprises a printer connection contact (A), a native chip connection contact (B) and a switch signal terminal (L). The native chip connection contact (B) and the printer connection contact (A) are connected by means of a switching circuit (1). The switching circuit (1) is also connected to the switch signal terminal (L). The contact control method for the regenerative chip comprises: under the control of the switch signal terminal (L), the native chip connection contact (B) and the printer connection contact (A) are connected or disconnected by means of the switching circuit (1). By means of controlling connection and disconnection between a printer connection contact and a native chip connection contact of the regenerative chip, the problem of signal interference and conflict caused when the regenerative chip and a native chip simultaneously send signals to a printer is prevented.
