I had the same issue mine sap out of use for about 4 months so the needle that injects the ink dried up on the end of the tip and I had to pull it apart and take some rubbing alcohol and clean the tip of the needle try that once but be careful to unplugged copier printer first I hope this helps
I have had a similar issue with my side by side fridge dispensing water and Yes mine was a solenoid relay in the back of the refrigerator always make sure to have the refrigerator unplugged when messing with electricity. Also on the back of the refrigerator should be a wiring diagram in a little plastic envelope taped to the back usually down on the bottom behind the plate for the compressor sits.
