Found this tip.
Model Name:ARM350,ARM450
Symptom:Machine Gives A E7-80 Or E7-90 Fault Code Or Blank Copies Or Paper Jams
Cause:Static discharge in the PS Roller Unit
Action: Ensure that the contact points of items 36 and 18 on page 5 of the parts
guide are clean. Also ensure that items 23 are clean.
Evil will always triumph because good is dumb.
Its all shits and giggles until some body giggles and shits...
thanks friend
in my case, is a ar-m451n, but i will chek.
regards
It can definitely be caused by a missing earth spring in the rego unit.

yes, i faced the problem also. the ps unit inside got 2 earth springs,one spring missing also can cause e7-90,machine hang up
problem solved, revision to the unit of ps roller, and firmware upgrade, because the copier was out of date. (yet v. n1.12)
thnaks one more time.
