Why can't all-in-one printers calibrate themselves with their built in scanners?

Like actually....

I understand scanners need calibrating.... but not nearly as much as printers....

Wouldn't it make sense to simply load whatever ink/paper, print out a specific color test sheet the firmware can recognize, scan it, then iterate on that process to calibrate the printer?

Sometimes my genius... it's almost frightening.

That software let you create printer profiles with a scanner , and you need an external reference target to start with to calibrate the scanner.

But why don't the manufacturers build this in to the printers?

It seems only logical. Calibrate the scanner from the factory, iirc those don't have the tendency to "walk" in calibration, and then make it a trivial matter to simply load a new paper and create an ICC profile. Save it into the firmware. Boom.

I'm thinking of course of my ET-8550.

oh well - it's all marketing - just get an Epson P5000 with a spectrometer or some similar models from Canon - and you get your profiles almost on the fly

They have printers with built in spectrometers?
