External Waste Ink Kit Installation: Epson PX730WD - Support

Printer Potty installation guide for the Epson Stylus Photo PX730WD (and equivalent models)

External Waste Ink Kit: Installation Process

We still have a legacy slideshow version of the instructions shown below and all Solo/Duo-X kits still include printed documentation that shows the same process too.

Note: If you have received a kit with two identical sized connectors (Steps 13-14) please remove and reverse the connector (on the blue clamp tube) so that larger end goes into the Printer Potty tube. This will allow you to use the thinner/smaller end to connect to the overflow tube.

Waste Pad Holder Modification and Reinstallation (Optional)

Reinstalling the waste pad holder (removed during tube installation) is not required but may be preferred.

Modification to allow the waste pad tray to be replaced with Printer Potty tube installed: Modification to allow the waste pad tray to be replaced with Printer Potty tube installed

This instruction details the necessary modifications required to allow the waste pad holder to be reinstalled after the Printer Potty tube part has been installed.

The process is entirely optional as the tray does not need to be reinstalled.

The process also relies on the use of sharp blades (saw/knife) and other tools to complete so extreme care should be taken. This process is undertaken entirely at the end users own risk.
Intended tube path: Intended tube path

The path is indicated as a dashed line where the current pad holder blocks it and need to be modified.
Remove waste pads indicated: Remove waste pads indicated

These pads can be disposed of or stored (if preferred)
Cut panel as indicated: Cut panel as indicated

A sharp craft knife is shown but a hacksaw may be preferable as a safer tool to make these cuts.
Score & break off panel: Score & break off panel

Use a sharp craft knife to score the plastic as shown, then carefully push the plastic over until it snaps off.
Panel part removed: Panel part removed

Once removed the piece of cut plastic/panel can be disposed of.
Cut panel as indicated: Cut panel as indicated
Score & break off panel: Score & break off panel

As before, score the plastic as indicated and then push over to snap off.
Dispose of waste: Dispose of waste

The path through the holder plastic wall panels is now clear.
Remove screw hole block: Remove screw hole block

The waste tube will exit through the existing screw hole. So, the block, that the screw normally rotates into, needs to be removed as shown.

A hacksaw is the only tool that will do this job.
Screw hole block removed: Screw hole block removed

The block can be disposed of once removed.

Note: The waste pad holder still has the plastic retaining clip to stop it falling back out.
Modification complete – Cleared tube pathway indicated: Modification complete – Cleared tube pathway indicated

That’s it… Now you just need to reinstall the waste pad holder.
Optional: Remove metal plate: Optional: Remove metal plate

The metal plate is not included on later models but regardless it is not needed for anything and can be removed.
Optional: Slide off and dispose of: Optional: Slide off and dispose of

The metal plate is secured by lugs that the plate slides off horizontally along it’s length, allowing easy removal if desired.

Remove and dispose of as required.
Insert tray lugs into front end of base: Insert tray lugs into front end of base

Reverse the tray extraction process by inserting the retaining lugs into the “front” end of the waste pad cavity.
Check tube path is unobstructed and lower pad holder: Check tube path is unobstructed and lower pad holder

Ensure the tube part is in the correct position as you gently pivot and carefully lower the holder into the cavity.
Lowering pad (Close up): Lowering pad (Close up)
Maneuver as required to allow pad holder into position: Maneuver as required to allow pad holder into position

Taking care not to crimp or catch the tubing, some adjustment may be required to get the pad holder into position and finish reinstalling it.
Pad holder replaced: Pad holder replaced
Completed installation: Completed installation

Once reinstalled the pad holder should act as a fail safe in case any of the connectors were incorrectly installed and pop off.
Full installation complete: Full installation complete

After initial installation, keep an eye on the waste ink generated and reaching the Printer Potty tank.

If no waste has appeared in the tank after more than 3 printhead cleaning routines, check the installation has not been compromised (eg: compressed tubing, popped connectors, etc…)

Otherwise you’re good to go.

Happy Printing!
