Finding and Fixing Leaks in the Fill Chamber

Objective: To explain how to properly run and evaluate a Syringe Leak Test

Step 1:

Check for cracks in the fill chamber door

• Small shallow cracks can be ignored
• Cracks that can be a problem are:
  • Cracks that run to the edge of the doore
  • Cracks around the center part of the door

Step 2:

Check to see if the door is seating properly

• Make sure the hinges are on correctly, screws/washers set properly
• Check to make sure the hinges are not broken

Step 3:

Look at the seal

• Make sure all of the small screws that hold the seal on and around the fill chamber are seated properly
  • Do this by  running your finger all the way around the seal and feel for protruding screws. If they can be felt, it may be the location of a leak.  If any screws need to be screwed down you can use a screw driver to take them down even with the seal.  If you go too far down the screw could go past the seal and the seal could come off

Step 4:

Inside the Chamber

• Make sure each of the four fittings on the end of the four injector assemblies is finger tight.

Step 5:

Back of the Fill Chamber

• On the back of the Fill Chamber there are four fittings as well.  Make sure all four are finger tight.
• In the older version of the InkCenter there are four proximity sensors with nuts holding the the holster onto the Fill Chamber.  Tighten these from the back of the chamber.  In the new models there are two nuts on either side of the holster that may need to be tightened.

Step 6:

Other-remove the work surface

• Make sure the dispenser lines (C) are tight
• Make sure the syringes are tight by finger tightening the screws at the bottoms of the valve body.
