Note the round silver disc in the damper where the two red arrows are pointing toward.
This is the filter and the one way valve to prevent ink from backing up from the capping
station to the damper. If it is not clean it will not let ink through to the head.
To Remove the Head
Before removing the head make sure the dampers are placed out of the way. You may
want to string them up with a rubber band.
When removing the head loosen the screws as shown below and drop the metal blade
out of the way. Pull the head out and remove the two ribbon cables. Handle the head
carefully. Do not put pressure on the bottom of the head.
