In one example in accordance with the present disclosure, a method is described. According to the method, a pump is selectively activated to draw print fluid from a print fluid delivery system towards a reclamation container. It is detected when a reservoir of the print fluid delivery system is empty. In response to an indication that the reservoir is empty, the pump is selectively deactivated to terminate a print fluid reclamation process.

A printer tray printed circuit assembly may include a board, a processing unit supported by the board, an output connector connected to the processing unit and supported by the board and an input connector supported by the board. The input connector is connectable to an interconnect to connect the first printer tray printed circuit assembly to a second printer tray printed circuit assembly. Signal altering circuitry carried by the board automatically alters an output signal of the output connector in response to the input connector being connected to the interconnect. The altered output signal indicates a configuration of a printer tray configuration.

An apparatus can comprise a locking mechanism comprising an elongated slot to receive a pin. The apparatus can also comprise an encoder strip adhered to the locking mechanism. The apparatus can further comprise a tension spring coupled to the locking mechanism. The tension spring can provide a force in a given direction to pull the locking mechanism in the given direction.
