Hi Liam
I have read with interest the posts. I can add a positive here. I think but stand under correction that some of the managed service issues listed may have been as a result of the incorrect devices. I have knowledge which suggests that OKI Executive Series products are better suited to the managed environment. Your supplier may be recommending this solution above the stand C series products. The ES as they are commonly known have different toners with higher capacities and yields resulting in a lower cost per copy. Maybe get them to clarify for you. I can only say that from my experience ES is the answer 0 good running costs, low downtime. Have you asked for case studies or customer referrals?
