Abstract
An example system includes an advancement mechanism to drive print medium into a stacking region, a clamping mechanism, and a controller. The clamping mechanism includes a trailing edge clamping arrangement in a trailing edge portion of the stacking region and at least one downstream clamping arrangement in a downstream portion of the stacking region, the downstream portion being downstream of the trailing edge portion. The controller is to sequentially actuate the trailing edge clamping arrangement and the at least one downstream clamping arrangement when the advancement mechanism transports a print medium into the stacking region.
Claims12
A system, comprising:
- an advancement mechanism to drive a print medium into a stacking region;
- a clamping mechanism, comprising:
- a trailing edge clamping arrangement in a trailing edge portion of the stacking region;
- and
- a downstream clamping arrangement in a downstream portion of the stacking region, the downstream clamping arrangement including a leading edge clamping arrangement in a leading edge portion of the stacking region and a middle clamping arrangement between the trailing edge portion and the leading edge portion;
- and
- a controller to sequentially actuate the trailing edge clamping arrangement and the downstream clamping arrangement when the advancement mechanism transports a print medium into the stacking region.
A method, comprising:
- advancing a print medium into a stacking region, the print medium being engaged by an advancement mechanism;
- actuating a trailing edge clamping arrangement when the print medium reaches a predetermined position in the stacking region;
- disengaging the print medium from the advancement mechanism;
- and
- actuating a downstream clamping arrangement in a downstream portion of the stacking region, the downstream clamping arrangement including a leading edge clamping arrangement in a leading edge portion of the stacking region and a middle clamping arrangement between the trailing edge portion and the leading edge portion.
A non-transitory computer-readable storage medium encoded with instructions executable by a processor of a computing system, the computer-readable storage medium comprising instructions to:
- detect delivery of a print medium into a stacking region by an advancement mechanism;
- actuate a trailing edge clamping arrangement in a trailing edge portion of the stacking region to secure a trailing edge of the print medium;
- release the advancement mechanism with the trailing edge clamping arrangement actuated;
- and
- actuate a downstream clamping arrangement to secure a downstream portion of the print medium in the stacking region, the downstream clamping arrangement including a leading edge clamping arrangement in a leading edge portion of the stacking region and a middle clamping arrangement between the trailing edge portion and the leading edge portion.
