Nevermind. Turns out the Canon iP4700 does, so I'm good. Thanks to all that replied. Oh wait, that would me.

As an ip4000 owner that has not crapped out, I wonder if you are really correct in your assessment, even though you may be only a quarter of the way correct. Because the ip4700 is a second generation chipped Canon. Basically your original ip4000 with a slightly better printhead.
To some extent you must understand the post 2000 inkjet competition, and the extent of the original Canon heresy. Because to gain inkjet market share, Canon introduced the BCI-3&6 set of non chipped cartridges and gained almost a 100% market share among the professional heavy user photoprinting set. Epson with a similar ink tank design was number two, and anyone with a printhead on the cartridge itself was quickly regulated to a distant third place among the very few who really knew what they were doing. And as a result, a huge third party market developed for prefilled clone BCI-3&6 that saved about 8x over Canon OEM replacement cartridges, and various third inks, that doubled that savings to 16x or so.
And when Canon bean counters noticed too many people were not buying their super high profit OEM cartridges, the Canon evil empire struck back with the new chipped PGI-8 and Cli-5 family family of cartridges. Basically wiping out the third party markets in the chipped process.
And even if Canon breathed easy thereafter, the third party market kept working, it took four or five years, but they finally cracked those Canon 1'st generation chips, and now a simple chip $30.00 chip resetter makes something like an IP 4200 into the same savings machine the ip4000 was.
But as soon as that first generation chip resetter became available, the Canon evil empire struck back and introduced the same 2'nd generation of as of yet uncracked chips found on your IP4700.
Meanwhile back at the ranch, what is wrong with your ip4000? The feed mechanisms last a long time, the rollers can be do it your self repaired, and printheads can be replaced for $60.00 or so. My ip4000 has passed page 10,000, its never seen a single OEM replacement Cartridge, and still works perfectly. And many Canons go 30,000 pages or more with no problem.
Nor should I only call Canon the evil empire, almost without exception, the word inkjet seem to be a license to steal by the entire inkjet printer industry.
When we deal with inkjet printer manufacturers right now, its not a matter of which is more evil, its a matter that they are all evil. But some may be marginally better than some other total rascal.
And until we consumers band together, we will all keep being screwed. As of yet, us consumers are hot beds of apathy, and as long as the cats away, mice will eat us out of house and home, selling those cheap and wondrous no armed bandits.
