Guidance for discontinued models and parts delivery
Thank you for your many years of support for our SUMIGRAPH series. Among the series, models shown below have been discontinued due to model change and other reasons, and almost 10 years have passed since the discontinuation. We have since made all our efforts to secure spare parts to be able to provide our customers with repair and maintenance services, yet we have fallen to a difficult situation to procure these spare parts.
Regarding repair and part supply for old model products, we have sent a notice letter below to each customer, but we are unable to contact some customers who have not notified us of changes in their contact address. Here, we would like to raise this issue again to call for attention of our customers.
We appreciate your loyal support for our products, and understanding our situation.
