6.13.12  PAPER TYPE AND DOUBLE-FEED DETECTION 
 
 
 
[A]: Registration Rollers 
[B]:  Double-Feed Detection LED (LED) 
[C]:  Double-Feed Detection Sensor (Receptor) 
 
After skew correction at the registration rollers, a sensor pair checks the 
translucence of each sheet. This function makes sure that each sheet of paper fed 
is of the same type and also detects double-feeds. If a sheet of a different type or a 
double-feed is detected, the machine stops the job and a copy jam error message 
is shown. 
After buckle adjustment, double-feed detection LED [B] (an LED) emits light that 
passes through the sheet above. The light is received by double-feed detection 
sensor [C].
