An encoded sheet material includes a sheet of material that has a first
surface, a second surface disposed opposite the first surface and an edge
extending between the first and second surfaces and peripherally about the
sheet of material. The edge has indicia arranged on it to form a code that
identifies at least one characteristic of the sheet of material. A sheet
processing apparatus uses the encoded sheet material and includes a code
reader device and a processor. The code reader device reads the code. The
processor communicates with the code reader device and causes the sheet
processing apparatus to process the sheet of material based upon the read
code. An encoded image recording medium and image recording apparatuses
are also described.
