Task: Wrong Candidate Generation
Input (English): Context: But it should work if I get the heads cleaned , and may need to clean the jets . The printer tries to print but no ink is on the page so I guess that is the problem since it set up awhile . Anyone know how many times to hold the button down or how to manually clean the heads ? Is there now a program for this ( I never did know how to align my cartridges - just hoped they aligned ) ?. 
Question: What computer equipment may I be trying to fix ? 
Correct Answer: The printer.
Output (English): The keyboard.
