Patent ID: 8310541

Claim:
A monitoring system for monitoring a printing system, comprising: a printing system module configured to interface with a primary printing-medium path of the printing system, wherein the printing system module includes a housing with at least one printing-medium path disposed therein, wherein the at least one printing-medium path is a sub-printing medium path of the primary printing-medium path; a first camera positioned to capture a first frame of the inside of the printing system module structure, the first frame displaying in real time an image of a side view of a print medium stack of the printing system module structure; a second camera positioned to capture a second frame of the inside of the printing system module structure, the second frame displaying in real time an image of a top view of the print medium stack; a third camera positioned to capture a third frame of the inside of the printing system module structure, the third frame displaying in real time an image of a liquid contained in a waste region, the liquid being illuminated by lighting having sufficient wavelengths to allow determination of the type of the liquid; and an image-processing component, wherein the first camera is positioned to determine whether a sheet of print medium in the print medium stack is curled or flat, the second camera is positioned to determine whether a sheet of print medium in the print medium stack is misregistered in the print medium stack, and the image-processing component reads the first frame and the second frame and determines adjustment parameters of the printing system to compensate for the detected curl and/or misregistration.
