Hi,Thank you for using Just Answer my name is ***** ***** I will help with your question.When you plug the printer in do the heads make any attempt to move?
Could you open the lid of the printer like you would if you were changing the print cartridges and make sure there are no obstructions.
Done that. The cartridges were out a little and were stiff to move along by hand
If you could try the printer again and see if it will attempt to move the heads
It made noise as though it wanted to start, then nothing. Yellow light flashes on and off
Is the light flashing on off on off or is there a sequence
It changes left to right continuosly
If you open the lid do the cartridges move to the centre
can you move the cartridges by hand? if they are very stiff do not force them
They will move but stiffly. The lower track looks as though it is clogged with black ink
The tracks tend to get a bit dirty do you use canon ink or compatible inks?
if you move the by hand when you close the lid does the printer move them home
Mostly Canon but black is compatible
that could be why there is more black ink around the rollers, compatibles tend to kill printheads because they are sometimes a thicker consistency than canons own inks. I dont think the inks is the problem, if there are no obstructions it could be the motor that drives the head has failed or the logic board in the printer.I would leave the printer unplugged again for a few minutes then plug it back in and see if it wants to move the heads back to there home positions.
