Vacuum Pump

Updated Aug 2, 2000

Here is an alternate way to charge a new CFS Unit. This unique Vacuum Pump can be used to fill the empty CFS cartridges.

This procedure is for unpunctured cartridges. Here is how it works -

Attach one of the CFS tubes to the end of the "Tube Adapter". Don't push it on too far, or it will be very difficult to get off. Just far enough to make a seal.

Pull on the plunger of the 60 cc syringe to create a vacuum in the CFS tube. (this takes some hand strength). Air from inside the tube and cartrdige will flow across Check Valve "A".

When the plunger is all the way back, push the syringe plunger forward, causing the air extracted from the cartridge to be expelled across Check Valve "B", while Check Valve"A" maintains a seal preventing air from going back into the cartridge.

Pull back on the plunger again, getting even more air out of the cartridge. Then push the plunger forward, expelling the extracted air out Check Valve "B". Do this at least 3 more times and a perfect vacuum has been created inside the cartridge and the CFS tube.

Next, fold the CFS tube in half about 3 inches from the Tube Adapter. Make sure it stays folded and the vacuum is not lost. Hold it tight.

Before you detach the tube from the vacuum pump, make sure your cartridges are properly orientated. See photo.

Detach the tube from the end of the Tube Adapter. Make sure it remains folded over and the vacuum is not lost. Insert the end of the tube at least one inch into the ink bottle without unfolding the bend (make sure it is the right color).

Slowly let the tube unfold. Keep the end of the tube 1" or more under the ink surface during this time. The ink will flow from the bottle, through the tube and into the cartridge. Be sure to unfold the tube slowly. The ink will surge into the cartridge. Some portion of the cartridge, in the front, will not get filled, this is normal and it will not interfere with the operation of the CFS.

Repeat this procedure for each tube on the CFS unit. Keep the cartridge on end, as shown. After all the tubes are full, set the cartridge on your bench in the installed position. Put something under one end to make it level. Let it set in this position for a couple of hours. This will let any trapped air rise to the top. After a couple of hours, the cartridge can be install in the printer. See the appropriate CFS instructions.
