Systems, methods, and computer-readable media are disclosed for optimizing a value of a dispensing parameter of a product dispenser based at least in part on product usage data. The dispensing parameter may include any suitable adjustable parameter of the product dispenser including, but not limited to, a dispense duration, a volume of product (e.g., a shot size), a sheet length, a capability of a user sensor to distinguish between genuine and false triggers of the sensor, a delay setting that specifies a delay time between successive dispenses, or the like. The value of the dispensing parameter may be optimized to align an actual performance outcome with a target performance outcome. The target performance outcome may include, for example, minimizing product usage per user, maximizing user sensor reliability (e.g., a percentage of dispenses that occur in response to genuine user-initiated triggering events), and so forth.

A sheet product dispenser for dispensing sheet product from a supply of sheet product reduces accumulation of the sheet product in the chute. The dispenser comprises a housing including a chute having a sheet product dispensing opening, a sheet product feed roller assembly disposed in the housing and configured to feed sheet product from the supply of sheet product into the chute, and a pusher disposed in the housing and configured to engage the sheet product fed from the sheet product feed roller assembly at a location downstream from the sheet product feed roller assembly and push the sheet product fed from the sheet product feed roller assembly toward the dispensing opening to reduce accumulation of the sheet product in the chute. A related method of reducing accumulation of the sheet product in the chute also is provided.

The disclosure concerns an interface for communicating with and for controlling the operation of an automatic hygienic sheet material dispenser. The interface includes a user sensor to detect the presence of a user within a sensing zone, at least one indicator for indicating the setting of an operational parameter, a main microcontroller, at least one additional sensor for adjusting a dispenser operational parameter or activating a dispenser function, and a protective cover including a graphical symbol or text. The at least one additional sensor, the at least one indicator, and the main microcontroller are located on a main printed circuit board located behind the protective cover and arranged such that the at least one graphical symbol or text overlaps with the at least one additional sensor or the at least one indicator. The main microcontroller is arranged to selectively operate the dispenser in a user setting or a maintenance setting.

A dispenser for sheet material may include a feed roller with an integrated cutting mechanism that is movable with the feed roller for at least partially cutting or perforating the sheet material during dispensing thereof.
