I have just had the same problem on one of these Canon MF4150 machines.
The manufactures warranty on our machine had expired just one week before this happened so I had to fix this myself.
The problem we had (which is very likely to be the same cause as yours) is when we removed some torn jammed paper, it had somehow pulled off a spring from inside the machine. The spring was linked to the paper jam sensor.
It does involve a LOT of work to fix it, and unless you are very 'techy' it may be quite a difficult task to do this for the 'average' person.
I had to completely disassemble the machine: Take off the front first (lift up the cover and there is 2 screws at the front and 2 clips on the bottom of the machine) Then remove the 2sides and finally the top (screws should be easy to see, to get the sides off, un-clip along the front edges and gently move them outwards and slide them backwards to release the clips on the back) being careful with the wires going to the scanner part). Then look for the fuser unit which is near the top at the back, there is a black rounded cover over the fuser. To remove the cover, look for 2 small clips one at each side and unclip the cover and gently lift upwards.  Under the cover on the left side you will see a small plastic rod which goes from the left side to a small tab in the middle, if you look about half way along that rod you should see a tiny spring, make sure this is clipped on properly and that you are able to rotate the rod and it should spring back to the proper position when you let go.
Once this is done, put it all back together again and it should work fine.

I'm sure a lot of other people probably have this same problem too so I hope this helps someone.

SOURCE: cannon MP510 printer has Error, - The type of print head

I solved this on mine by removing and reinstalling the print head.
1. Remove and set aside the ink cartidges (don't make a mess)
2. lift the gray print head lock lever that is to the left of where the ink cartridges go.
3. Lift out the print head out without touching the ink ports inside, the contacts on the back, or the print nozzles on the bottom. The print head is the grey thing with circular ink ports that seat the ink cartridges. there are good pictures in the PDF of the Easy Setup Instructions available on the Canon Printer website. Look under the printer, then support, then downloads: http://gdlp01.c-wss.com/gds/0900002776/mp510_esi_us_v2.pdf .
4. Put the print head back in, lock the lever, reinstall the cartridges in the roper positions. And voila!
If this doesn't work you may actually need a new print head.

Hello there
You may not see a paper jam, so this is worth trying.

This may work for you, it has worked for many here I given this advice so gave it a try it could work for you. Generally when this happens, something has fallen into the printer, or a piece of paper has been jammed in there.

First step, remove the ink cartridge, and turn the printer upside down and gently shake it, see if anything comes out.

If nothing goes, or you can't hear anything rattling around, get a piece of cardstock paper (60lb or heavier) and gently push this through the printer, to see if it will help push out what might be stuck in there.
And gave the rode that the ink slides on a good clean and maybe a bit oil on cloth and wipe the rod with it.

Also clean The purge unit, called a spittoon assembly in an HP, Lexmark, Caonon and other inkjet printers, is where the print head assembly parks when not in use, also its other job is to clean and make sure the print head is clean and open for printing.

That is where you'll find the print head assembly parked on top of it.
It also has an electrical pump to milk the print heads and test for ink flow.

So clean all under where the heads are parked and on IP6600D models you can take out the heads just by clipping them out, and then clean well.


Please come back and just gave a vote, it will gave me some satisfaction to know am helping some one so I will keep on helping.
