Paper cutting mechanisms for cutting paper in a printing device including a drive mechanism, a cutting device coupled to the drive mechanism, and a retention mechanism including a trigger and a retaining portion configured to mechanically interact with the cutting device to selectively deploy the retention mechanism to retain the paper. In some examples, paper cutting mechanism includes a trigger including an elbow, a first arm extending from the elbow, and a second arm extending from the elbow offset from the first arm, and a rotation shaft extending from the elbow transverse to a plane defined by the first arm and the second arm. In some further examples, the paper cutting mechanism includes a resilient member cooperatively coupled with a paper engaging end of the retaining portion.

A method for rehabilitating manholes and other sewer collection system structures begins by repairing existing leaks using hydraulic grout and cleaning the interior surface of the manhole by sandblasting or the like. A waterproofing stage is applied in multiple coats using a crystallization agent that integrates a crystalline structure with the underlying substrate. A chemical attack resistant calcium aluminate cement stage is then applied, and the waterproofing capabilities of the underlying coating are enhanced by the integration of the crystalline structure with the calcium aluminate cement stage. An epoxy coating is applied on the calcium aluminate cement to provide further chemical resistance and waterproofing while simultaneously providing a continuous, bridging barrier during self-repair of cracks in the underlying calcium aluminate by expanding crystallization by the crystallization agent.
