-- in the input Itm the paper go furder 4 inches
please any idea or suggestions here is 2 pictues and one video showng the issue

 

Did you clean the infeed sensor? I had some similar problems and turned out i had to take out sensor and clean it with a rag cause of IO fumes.

 

Have you tried to exchange between stop stations or replace with a new one? I had this issue last year and fortunately I had a new stop station. But yeah first you need to be sure the input sensor is clean. Oh and also.. I don't know if the 5000 uses this, but in the 5600 there is a plastic coupling in the Input Feed Roller that with time it just breaks and causes input jams similar to these.

 

yeah i clean the input sensor and there's option you can bypassed and i switched the stop station still have the same issue ,when i click transport i go under the bridge and see the stop station input engage for second ,i checked the feed roller they are working fine.. no they are not like the 5600,when i push the inching botton the stop station engage and the gripper open i can send a video

 

i changed the stope station and replaced all sensors and it work ,thanks for all the reply
