Inkjet Printer

Question 1

1) what happens first?

Answer 1

Tiny droplets of ink are forced out of a fine nozzle, making them electrically charged

Question 2

2) what happens to the droplets?

What is applied to the plates?

Answer 2

• The droplets are deflected as they pass between two metal plates
• a voltage is applied to the plates - one is negative and the other is positive

Question 3

3) how do the droplets react to each plate?

Answer 3

• the droplets are attracted to the plate of the opposite charge and repelled from the plate with the same charge

Question 4

4) What happens to the voltage across each plate?

What happens to the droplets?

Answer 4

• the size and direction of the voltage across each plate changes so each droplet is deflected to hit a different place on the paper

Question 5

Final result

Answer 5

• loads of tiny dots make up your printout
