I've just finished setting up a new Color imageCLASS MF665Cdw that I purchased in part because it had a 600dpi scanner. And indeed, I see that resolution in the Canon MF Scan Utility. But that resolution is absent from the device's eSCL scanner capabilities, so I can't seem to get 600dpi resolution from other scanning software.
Here's how I retrieve the capabilities, and a few excerpts showing the resolution is capped to 300:
curl -s http:// 192 . 168 . 50 . 49 : 80/eSCL/ScannerCapabilities
<scan:PlatenInputCaps>
<scan:MaxOpticalXResolution>300</scan:MaxOpticalXResolution>
<scan:MaxOpticalYResolution>300</scan:MaxOpticalYResolution>
<scan:AdfSimplexInputCaps>
<scan:MaxOpticalXResolution>300</scan:MaxOpticalXResolution>
<scan:MaxOpticalYResolution>300</scan:MaxOpticalYResolution>
<scan:AdfDuplexInputCaps>
<scan:MaxOpticalXResolution>300</scan:MaxOpticalXResolution>
<scan:MaxOpticalYResolution>300</scan:MaxOpticalYResolution>
How can I get 600dpi in eSCL?

I called Canon and learned that this is just the way it is, it's not considered a bug. Scanning in the (standard!) eSCL way is limited to 300dpi. This seems consumer-hostile to me. I feel that I should be getting the full scanner capabilities when using standards-based tools, not having the best dpi locked behind Canon's own software.

Agree completely! Just purchased the same model, and ran into the same issue. Shame on Canon, but I'm not surprised at all.
