Under normal operating conditions, only the Multi-Feed Detector Enable button is illuminated. See the
reasons listed above for some reasons why both Multi-Feed Detector buttons may be continually illuminated
and an E204 error is displayed on the operator interface.
A-61139 March 2000
Probable Cause
The scanner has encountered
a multi-fed document, or the
document missed the sensor.
Depending upon the scanner
configuration, the transport will
stop and display an E204 error;
just display a warning message
or beep and display a warning
message.
During calibration, a document
that was too thick was fed.
Upon starting the transport, it
stops with an E204 error.
The thickness sensor may be
mechanically retracted but the
Multi-Feed Detector is enabled.
Encountered a skewed
document.
Document feed missed the
sensor during calibration.
Remedy
Press Run or either Multi-Feed
Detector button. This
automatically re-enables the Multi-
Feed Detector.
Restart the transport and calibrate
again.
Check to make sure the
sensor is not stuck out of
position or the sensor is not
retracted.
Restart the transport.
Extend the thickness sensor or
disable the Multi-Feed Detector.
Press the green Run button to
continue.
Refeed the document so it passes
under the sensor to complete the
calibration.
