Explanation
The envelope feeder pass thru sensor activated but never
deactivated. (x1=Media Size)(x2=Media Source)
This error can be caused by an envelope over the pass thru
sensor. Remove the envelope and try to feed an envelope. If
the envelope stops over the pass thru sensor, try the
following:
*Select the diagnostic test menu, select input tray sensor
tests, select envelope feeder sensor test.
*Check the envelope pass thru sensor to ensure it is
operating correctly. If the sensor test fails, go to the
"Envelope Feeder Option Service Check" on page
If the test passes, look for anything that might cause the
envelope to stop over the sensor.
An envelope never activated the envelope feeder pass thru
sensor or the sensor never sensed the presence of an
envelope. (x1=Media Size)(x2=Media Source)
*Check to make sure the envelope feeds to the pass thru
sensor.
*Check to see if the envelope actuates the pass thru sensor
flag.
