We have a couple of machines of X Genus intraoral x-ray units manufactured by de Gotzen, Italy, with similar issues. the machine does not come with a service manual instead an operating and maintenance manual. it shows ERR initially, then ERR 01 if anyone can help with the issue, it would be great.
de Gotzen is currently a part of Acteon group and the model has been renamed to X Mind.
