6.14.13 DOUBLE-FEED DETECTION
[A]: Registration Rollers
[B]: Double-Feed Sensor 1 (LED)
[C]: Double-Feed Sensor 2 (Receptor)
After skew correction at the registration rollers [A], a sensor pair checks the
translucence of each sheet.
After buckle adjustment, double-feed sensor 1 [B] (an LED) emits light that passes
through the sheet above. The light is received by double-feed sensor 2 [C]. This
function detects double-feeds.
If the machine detects a double-feed at the registration rollers, this page and the
pages being fed are fed out of the machine (to the finisher’s proof tray) or a jam
alert is issued, depending how the User Tool feature is set:
User Tools > Adjustment Settings for Operators > SP 1908 008
Next, the machine stops the job and a copy jam error message appears.
