imageCLASS MF753cdw Print Resolution 600 dpi vs 1200 dpi

[JayChow]

I see 2 different resolution specs of the same printer: imageCLASS MF753cdw

https://oip.manual.canon/USRMA-7178-zz-SSM-750-enUS/contents/devu-mcn-spec-basic.html?search=MF753Cd...

Print Resolution: 600 dpi × 600 dpi

But at 

https://www.usa.canon.com/support/p/color-imageclass-mf753cdw#idReference%3Dspecifications

Print Resolution: 1200 dpi × 1200 dpi

Which is correct?

Thank you.
