Question about Canon PIXMA MP780 All-In-One InkJet Printer
After replacing the black inks the printer would not turn back on? my wife says she smelled something burning and turned it off! and we could not turn it back on? i thought it was the ink that smelled?
It's possible that the printhead has burned out and in the process it's blown the printer in the process.
You can try one trick that has worked for me in the past but it's by no means guaranteed.
- Disconnect the printer from the mains/power socket!
- Remove the cartridges and printhead
Work out how to remove the left panel (left when looking at front) and then identify the power pack which is like a module that plugs into the printer.
Into this power pack goes one or two small internal connectors which you should disconnect, wait 10 seconds and then reconnect.
Push the power module back into position if you've had to release it, and then try plugging the printer back in to the mains/power-socket and try turning the printer on.
If it DOES comes back online, you should get a brand new printhead ASAP.
IMPORTANT: DO NOT use your old printhead as it will blow the printer or any other printer that it is installed in.
If it doesn't come back on then it's toast and it's time to look for a new printer.
I suspect you will find the printer is dead but if it does come back online you'll have dodged a bullet that took my MP750 and iP4000 to printer heaven. The fix above worked for a couple of iP4200's and an MP500 so it could still be ok.
