SC402-64

Have a Ricoh MP C8002SP with a SC402-64. Have swapped potential sensors and drum units with no success. Will let us run Color Registration and Manual is leading us to replace the LD unit. Any ideas???

Had the same thing last week. When I replaced the humidity sensor (behind the black drumunit) the error whent away.....I hope
