Note: This printer is physically, exactly the same to the Epson Stylus R250
The R240 is one of the “trapdoor” type of printer so really this guide is just a reinforcement of other guides like the R300, R220, etc.. That said the printer design is subtly different enough that locating the waste tube is a bit trickier for the uninitiated.
This guide though will give you everything you need to get it up and working.
Resetting the waste ink counter
The R240 and R250 are not supported by the SSC utility or the Epson IPR.
There are AdjProg utilities that will reset this printer but searching is required to locate a copy. For speed, use of the WICReset utility is recommended however.
Please remember that Feedback and/or comments on this guide are welcome.
