Pass through Sensor

Check for any debris, pieces of

 

 

envelope and so on over the pass

 

 

thru sensor. Check for correct

 

 

installation of the pass thru sensor

 

 

flag. Make sure the sensor cable is

 

 

attached to the envelope system

 

 

board. Perform an envelope feeder

 

 

sensor test to check both the sensor

 

 

and sensor flag.

 

 

Note: It may be necessary to use a

 

 

small tool to actuate the sensor flag

 

 

because it is located under the front

 

 

cover. Be careful not to damage the

 

 

flag.

 

 

If the test fails, check the flag for any

 

 

signs of damage or binds. If

 

 

incorrect, replace the flag. If the flag

 

 

is operating correctly, check the

 

 

voltage at J3-3. The voltage

 

 

measures approximately +5 V dc. If

 

 

incorrect, replace the envelope

 

 

system board. If correct, check the

 

 

voltage at J3-2. The voltage changes

 

 

from 0 to +5 V dc when the flag is

 

 

moved in and out of the sensor. If

 

 

incorrect, replace the sensor

 

 

assembly. If this does not fix the

 

 

problem, replace the envelope

 

 

system board.
