Printer Potty installation guide for the Epson Stylus Photo PX730WD using the Duo-X waste ink kit.

Note: The Duo-X Printer Potty kit is an updated version of the Solo-X and takes care of a secondary waste ink tube that acts as an overflow.

Installation Process

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

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.

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.

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!
