Abstract: Provided is a printing apparatus having a support member with a printhead slot, a first tubing to provide a first printing fluid, and a second tubing to provide a second printing fluid. An end portion of the first tubing is arranged in an active position to provide the first printing fluid to a printhead in the printhead slot. An end portion of the second tubing is arranged in a standby position to not provide the second printing fluid to a printhead. A mechanical structure to which the end portion of the first tubing is attached allows to remove the end portion of the first tubing from the active position and to arrange the end portion of the second tubing in the active position.

Abstract: In an example, a printhead carriage to be used in a printing system is disclosed herewith wherein the carriage includes a pocket defined by a first wall and a second wall opposite to the first wall; a set of electrical connectors provided on the first wall; and a mechanical protector. In an example, the mechanical protector may be a sheet with a determined length that extends from the first wall into the pocket and a width that extends along the width of the first wall over the electrical connectors. In an example, the mechanical protector includes an elastic member biased towards the second wall.

Abstract: Systems and methods for printing are described. One example is a tension module for a printer including a throughput roller including a length to diameter ratio of at least 10:1 and a material on the surface thereof having a friction coefficient value less than 1. In addition, the module includes a plurality of pinch rollers arranged parallel to the throughput roller and, the pinch rollers supporting the throughput roller and providing a pressure on a print medium when passed along the throughput roller. Further, the module includes a motor to rotate the throughput roller. Still further, the module includes a tension lever including a plurality of stops, each of the stops being associated with one of a plurality of tension settings. Manipulation of the tension lever between two of the stops adjusts the pressure between the throughput roller and the pinch rollers on the print medium.
