Farmer Dave,I’ve had great success running envelopes on our Canon C710. The envelope attachment for the paper deck is incredible at feeding. However, the smaller A envelopes don’t work.
we just got an Xante Enpress, and I haven’t been wowed yet. The only thing is I can load a box of 500 instead of 250 on the canon. But canon is faster….
Please get in touch with me, I would love to see your setup. I bought an envelope feeder with my 910. Doesn't run worth a damn. I'd like to know who your service provider is and what they have done differently than mine.
