Abstract
The presence of a radio frequency signature () on a cut sheet of print media () is detected by a radio frequency interrogating device () to determine it's relative left/right position on the print media (). Either the leading edge () or trailing edge () of the print media () is detected by one or more print media sensors (). A print controller () can note the time (t) when print media is detected and cause the radio frequency interrogating device () to detect the radio frequency signature () at a time (t) when the print media has reached a predetermined point along the print media pathway (). The position of the radio frequency signature () on the print media () can be calculated using the time differential (t-t) and the known angular displacement of the radio frequency interrogating device ().
