We've had an Impressia two or three years. We use it maybe once a week on average. A few months ago, the output conveyor went to pot. Now one set of belts on the Enterprise feeder is dead; the other set still works. I suppose a motor has burned out, but it's not like we worked it to death. I can't find any helpful info online. Is there anything we should be doing as far as maintenance? I can't find out how to oil anything or do anything else other than keep the belts and rollers clean with a damp cloth.
