I just had a look at the comparison page for the ip4600 and the ip4500 in order to find how Canon intends to sell these new models. It seems however that Canon is being quite frank as they admit that their old 4500 was a better printer. Look at this or read this small commentary on any characteristics where a difference was found:
Black yield
4600: 350 pages
4500: 525 pages
Expect to replace black cartridges every 250 "real" pages of plain text on the old model. That's really bothersome for heavy office users.
color yield (each color)
4600: 505 pages
4500: 935 pages (almost double!)
Almost double yield for the old model! I think "yield" is something of a nuisance to printer manufacturers.
Speed
4600: 21ppm (Max.), 11.2ppm (Standard)
4500: 24ppm (Max.), 11.7ppm (Standard)
The old model is FASTER!
Borderless 10 x 15cm at high quality speed
4600: 20 seconds (Standard)
4500: 21 seconds (Standard)
Practically the same, but let's not deprave the new model of its few laurels.
Media Weight
4600: Canon special media up to 300 g/m
4500: Canon special media up to 273 g/m
Probably refers to Canon's new media.
Two sided printing
4600: auto select on plain paper
4500: auto select on Photo Paper Plus Double Sided, Super White Paper or plain paper
Is this really true? The new model can't recognize the old two-sided media?
Power:
4600: Standby ~ 1.3W, off ~ 0.5W, printing ~ 14.0W
4500: Standby ~ 1.2W, off ~ 1.0W, printing ~ 13.0W
The old technology was less power hungry.
Noise:
4600: 45.5 dB(A)
4500: 34.5 dB(A)
Interesting and serious. The ip4600 is much noisier than the ip4500 -- to a level that can be upsetting. I guess Canon has removed some "useless" noise dampers-shields to minimize weight and costs, thus increasing noise.
Weight
4600: 5.7kg
4500: 6.9Kg
See above.
