If everyone recalls the European shareholders held out for one year as the Wide Format division was undervalued. So for one year Canon ran Oce as a dealer in the US.
They proceeded to sell their color products without PRISMAsync and sold price on their converting the hugely successful 3165 base to their generic product.
The former Oce Printing Systems group continues to carry any new tech forward with Ink Jet. In fact the 'highly innovative" ix300 ink jet has part and technology from the VP6000...as do their new V series products.
The Canon culture drove many highly talented people away from the industry and its comical that the hang onto that albatross of a CHQ in suburban NY with the hope that people will be lured by a horrific commute to work for them.
Without the Oce acquisition Canon would be long gone....so after 15 years was it a success...the answer is yes.
