Cannon ip3000, printer power comes on, but green power light goes out immediately.

Canceled the jobs on PC and verify the inks.If you use the refill inks perform the head cleaning in the mantenance mode.

If you have tried multiple cables in multiple working outlets then you need to contact the manufacturer for warranty or return it to the store.

Some possible solutions:

Disconnect and reconnect the USB cable to ensure a secure connection

Press the POWER button to power on the printer

Select the correct port setting (Windows)

Set printer from Offline to Online

Set the default printer (Windows)
Try a different data cable

These sound like unrelated problems. Uninstall the hard drive, and test if the printer light goes on.
Make sure the printer is connected properly, make sure the power cord is connected snuggly.

I have the same problem. I don't really know what to do. Think its broken. guess we have to buy a new one, I'll buy an Hp instead. hehe

5 flashes indicates a faulty printhead or possibly a problem with the p/head contacts. Try removing the head which is easier if you take the cartridges out first(no tools required) and re-seat it having checked the contacts for dirt.

If that doesn't work it may be that the waste ink tank is full. Try this ...

6A00 means the purge unit is stuck, it's the unit on the right that cleans the printhead. If you can see on the right, look for any paper scraps or things that don't belong. Otherwise it's a shop repair.

I have a pixma too, they are getting old, but as long as they still work who cares?
Mine started to print green tinted pictures lately, now I'm searching boards and looking for the solution to that. I put in a service request to canon usa, but haven't heard from them yet, maybe never will.
Long Live PIXMA's !

I've just checked mine as it suddenly stopped working - does not even light up the green button.

I'm getting 8 volts Red to Black and 23 volts Red to Yellow so I guess it's fubared?
