Question about Canon PIXMA MP830 All-In-One InkJet Printer
I encounter exact same problem. What I did was took out the print head and clean the print head with Qtips with alcohol. To locate and remove print head, follow the instruction at Canon's PIXMA MP830 website and choose the tab
"Support & Service" type "rseating the Print Head"
You'll be seeing
Basically, printer head is inner carton where ink cartridges sit.
Above link shows pricicely how to remove the ink cartridge.
Above link's instruction says, Caution: do not touch print head nozzles<1>
But, I just went ahead and clean the print head nozzles with rubbing alcohol soaked Qtips.
After completely cleaned and dried, I reinstalled print head, reinstalled ink cartridges,
closed all the cover. It went back working perfectly.

The solution to my problem had nothing
to do with an actual wrong print head, nor anything needing cleaning. After a month of thinking if I should take
the printer to a technician and pay for who knows how much, I thought on
checking the printer myself one more time. I wind up looking straight at the source. The rear part of the print head has an “electronic”
strip which connects to the printer when it is seated in place. This strip has a couple of tiny metal squares
where the information is passed on to the printer given that it connects to the
small metal pins on the printer side. If
one if this pins happens to be bent (apparently in mine it came like that from
factory) then the message of “wrong print head” installed will appear. The reasons are obvious, but it sucks that
they didn’t write a better program that would address this problem and give a
more specific message. Something like “improper
connection to print head”.
Anyway, I went and took a pointy set of pliers and pulled out the pin and unbend it as well. Be careful doing this, if you pull it too hard or try to unbend it too much you may brake it, and there it goes. You may have to order that rear part. The pin I pulled out and unbend didn’t look as well as the others, but the printer works fine now.

My MP830 displayed the "incorrect Printhead" message after about
1.5 years of very light service. The problem was that the printhead
had started leaking ink into its electronics, which then shorted out
and gave the incorrect diagnosis. At least it knew its problem was
something to do with the printhead. Otherwise this printer works
pretty well, except for wasting enormous quantities of ink trying to

I have another problem: I got the "incorrect print head" message, but now the print head/cartridges are stuck out of sight and I can't access them. Any suggestions?

Try unplugging the power cord and leaving the printer off for a few minutes. When you plug back in, allow the printer to initialise and then raise the cover. The print head assembly should then appear.
