As I'm in the market for one, it's really great to hear about a new and
good quality printer/scanner which is working with Linux.  I still have
a few questions about it though, if people would be so kind as to give
information about the Canon Color imageCLASS MF644Cdw:

Does scanning also work from the flatbed (platen) and via the manual
feed slot (aka Stack Bypass)?

According to
https://www.usa.canon.com/internet/portal/us/home/support/details/printers/color-laser/color-imageclass-mf644cdw/?tab=richtexteditortab_5417439e-0c5b-4a4c-8b4f-54ba103c6eba,
the scan resolutions for this unit are 300 x 600 and 600 x 600 dpi.  It
would, of course, be really nice to achieve higher resolutions.  Are the
Canon-stated resolutions perhaps limited by their own Windows and Mac
software?

Can copying be done with this machine without a PC being connected to it?

What document formats are available for scanner output (on Linux of course)?

Finally (and sorry for the slight OTness), do all the printing functions
of this model work for Linux?  (Neither the Linux Foundation
OpenPrinting.org site nor tldp.org list it.)

Thanks much for your help.
