An example media handling system includes a web media holder with a core hub capable of coupling to a core of a web media roll, a sensor to take a measurement at the circumferential surface of the web media roll, and a controller to determine a length of the web media roll. In that example, the controller may determine the length of the web media roll based on a first distance measurable by the sensor when the core hub is in a first orientation, a second distance measureable by the sensor when the core hub is in a second orientation after a number of rotations with respect to the first orientation of the core hub, and reference value corresponding to the core.

A system and control method for determining an amount of paper product dispensed from a dispenser or remaining in the dispenser is provided. The paper product is initially loaded in the dispenser as a paper product formation, such as a roll or stack of the product. At defined intervals, a digital image of an aspect of the paper product formation in the dispenser is taken and transmitted to a digital imager processor. A feature of the digital image that changes as the paper product formation decreases in size as the paper product is dispensed is analyzed and compared with a predetermined value of the feature at a predefined size of the paper product formation to determine an amount of the paper product dispensed or remaining in the dispenser.

An apparatus and method for tracking defects in sheet materials. The abstract of the disclosure is submitted herewith as required by 37 C.F.R. 1.72(b). As stated in 37 C.F.R. 1.72(b): A brief abstract of the technical disclosure in the specification must commence on a separate sheet, preferably following the claims, under the heading Abstract of the Disclosure. The purpose of the abstract is to enable the Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure. The abstract shall not be used for interpreting the scope of the claims. Therefore, any statements made relating to the abstract are not intended to limit the claims in any manner and should not be interpreted as limiting the claims in any manner.

A sheet delivery system includes: an end section detector which detects a position of an end section of a sheet; an end section conveying apparatus which holds the end section of the sheet and which conveys the end section of the sheet to a joining unit; a roll driving motor which rotationally drives a standby-side original material roll around a central axis thereof; and a suction roller which is capable of coming into rolling contact with an outer peripheral surface of the standby-side original material roll, and which includes an outer peripheral surface capable of suctioning the end section of the sheet in order to separate the end section of the sheet from the standby-side original material roll. The end section detector is attached at a position which enables detection of the end section of the sheet separated from the standby-side original material roll by the suction roller.
