At the head you said 'paper thickness position'and then you seems to have ignored that and did all the other things.
Is there an adjustment for paper thickness, a lever perhaps.
It does seem to be with the paper feed or paper presence detection.
Take a look around, is there something stuck in the paper feed track?
Can you have pass a piece of paper through without it rucking up?
Do these things see what happens

Had the same problem with my I550. Was going to buy a new printer
(I4000) since I could get one for about $30 more than the price of a
new print head. I like canon printers with the individual ink tanks and
have had no problems with the I550 for about three years.
to try moving the paper thickness lever back an forth a number of times
since some of the error messages indicated it could not determine the
setting of the paper thickness lever. I don't know how the printer
determines this switch setting but I thought if some contacts are
slightly oxidized that movement might break up some of the oxidation.
After operating the lever about a dozen times the printer started
working. Hope this will help.
Did you try moving the paper thickness lever (blue lever on top of the print cartridge holder)? It should be all the way to the left when you start--if it needs to be adjusted the printer message will let you know.
The U043 error code indicates that an ink tank is not installed. One or more ink tank icons on the LCD should also be lit up. The lit up icon indicates the applicable ink tank. Verify these tanks are indeed fully seated in the print head and that they are lit up red.
You can also press the OK button to clear this message and continue.
