These instructions show how to modify the CX6600 to redirect waste ink from the printhead cleaning function to an external waste ink tank.
Locate and Remove the Trapdoor
The picture (#1) on the left shows you the location of a trapdoor found on the base of the printer.
You will need to prise open this trap door using a slim and very strong
instrument such as a small jewellers screwdriver to gain access to the waste
|Once you've managed to prise open the trapdoor you should see the waste tube running close by as shown in picture #2|
Release the tubingWhen I attempted this myself I cut the tubing, but it turns out you can release the tubing without cutting by locating it from above by opening the printer and locating the metal butterfly clip that holds the tube in place.
To clear the printhead out of the way and gain access to the waste ink tube:
You should see the inside of your printer as shown above (minus the continuous ink supply tubing)
Once you have located the clip you carefully press the two "wings" together
and slide the clip up the tube. The clip normally keeps the tube in place
so by removing it you will find it easier to release the waste tube from the
With the tubing release you should now be able to see something like this (see picture #4 - left)
Extend the Waste ink Tube
You'll want to extend this tubing using your waste ink kit or some tubing you have available but whatever you do it's advisable to:
How? Simple, the barb won't pass through your hole (or shouldn't if you drilled is small enough!) so it acts as a sort of brake.
Raise the Printer
Once you've checked the system is connected properly you then need to push home the trapdoor and place the printer on a raised area that allows the waste tube out of the base of the printer without crimping or placing any kind of strain on it that would create a blockage.
Of course you could simply drill a hole in the desk/table where your printer
sits but this isn't recommended as parents, wives, etc... tend to frown at
this sort of thing. You can also cause a free-flow syphon effect if you place
the waste ink tank/kit too far beneath the printer.
The CX6600 is one of the most wasteful printers when it comes to waste ink pushed out during a printhead cleaning cycle so this modification is well worth the effort.
You can also use the SSC utility to reset the waste ink counter if you prefer
