Duplo error code J-710

Duplo 10/20 collator Error code J-710, can anybody explain?

 

Hi sir:
Will be a great Help,:
1) if you test the +5vdc +24Vdc if there are in tolerance, normally +o - 0.5% Up or down in the Power supply
2) Clean all sensors that machine has,
3) Look for some limit switch open or fault , loose in covers or doors
if that correct the voltages, what is the sympton that machine present?

 

Thank you for your reply, the error has cleared.
Cheers!!

 

Thank you sir
