Trim a business card to the width of the module opening. Moisten about 1/4" of the end of the card with DeoxIT D-Series. Insert and remove the card into the module a bunch of times. If it's a contact problem hopefully this will take care of it.

Does the problem occur with all ports?

Thanks Dave, I will definitely try that.

Yes, I tried three ports on two different 71b machines.
