For Canon MP470, I have an error

UO51 Print head is not installed. Install the print head.

The other error is

U163 The ink has run out. Replace the ink cartridge.

Can you help me?

Without looking up the error codes, from the wording I'd simply try replacing the ink cartridge with a new, genuine one.

Here are some possibilities:

1. You;re using refilled or non-original cartridges and the printer is complaining.
2. The ink cartridge isn't snapped into place properly.
3. The electrical contacts on the cartridge or the matching ones on the printer are dirty or damaged
4. The printer is broken

You could also Google the error code.
